Overview of Davey's Garden System Water Pump
Here’s to a miniature water pump type designed to hydrate small buddings, flowery shrubs, plants of thin stems and the abundant yet easily grown carpet grasses. The Garden System by Davey promotes a pressurisation that’s meant to be as innately gentle as possible, and this is built so your surrounding greeneries would be treated very delicately that a water splash wouldn’t pierce like a cut. Flip open a switch to get this electropump in use, permanently attach it to a power supply, or turn off routinely to place this centrifugal pump aside, the Garden Watering System remains easily installed to operate without additional setting required.
For versatile means, an automated sprinkler can be fitted to enable time-based plant showering, or make a trickle irrigation to slow but steadily drip hydration onto seedlings and shoots. A tube can also be attached onto Davey’s Garden System water pump to begin hosing down traditionally, yet whichever of the method you’re using for your own lawn, any one of the type is more than merrier to get the drenching job done. To top it off, a rainwater harvesting tank may further be fixed in to utilise the natural resource of downpouring found, this is applied as a water supply substitute rather than relying solely on SYABAS, Penang Water Supply Corporation, or other state-level ration providers, making all the more greener in conscience with this water pump use.
Various different models are also available with this electropump category, and this comes with both manual and automatic in operation. Each of the versions will be in stainless steel housing, and an integral metallic introduction to resist against rust, as Davey’s Garden System centrifugal pump is out in the open and basked under seasonal moisture while running dampening needs. And among Davey’s staff, partnered distributorships, as well as retailers, this Garden System is further known as the Domestic Garden Pump Range internally, and can be classified as one of the Home Pressure System.

Method of Identification For Davey's Garden System Water Pump
For orderly categorisation, Davey’s Garden System water pump is found uniquely identifable with a systematic encoding namesake. This purpose is used to recognise a centrifugal pump no matter the time and development found, and this leads to finding the available spare parts, if any, in case your very own Davey’s Garden System needs a future overhaul. This is important because each water pump has its own range of replacement components available, which may not fit another when problem arises. The method of identification for the Garden System water pump begins with:
- A shortened pump naming, where ‘SJ’ stands to represent Garden System in jet adaptation.
- Followed by two digits behind the alphabet, and this imitates the nominal flow rate in Litre per minute (LPM) at British English Piping.
- A dash comes after, and is succeeded with another two numerical digits displaying the overall cut-in pressure in bar that will be 10 times in value.
- A ‘PC’ at the water pump’s rear showcasing Pressure Controller as an identifier.
Based on the image found here, the product code (SKU) is SJ60-08PC, foretelling that this is one of Davey’s Garden System water pump that produces 60 litre per minute as its nominal flow rate, while having a cut-in pressure of 80 and again, an integrated pressure controller as part of the pump’s element.
Pump Accreditations
The gradual gathering of world-recognisable accreditations, as well as regional-based certifications have been received under Davey’s Garden System water pump. This principle is acted upon under the resulting interest of expanding our very own centrifugal pump’s recognition, where regulatory approval emphasizes more consumer trust across the different cultural landscape.
In addition, the credentials obtained for Davey’s Garden System water pump can also be a pre-requisite to the market-entry requirements of different continental exporting, and this is because of the different legislations in unique places that deems the compliance a necessity. Other benefits holding the various seals of endorsement for this electropump includes:
- Quality Factor: With geographical administrations on acceptable benchmark quality, renewal auditing and occasional sudden inspection combined with community feedbacks and industrial update, Davey’s Garden System water pump becomes an icon on-par with globalisation.
- Lightening Risk: Whether newer technologies become introduced or even the implementation of latest materials in a water pump, uncertain risks may come to rise and this is due to the exposure of temperature and atmospheric conditions across time. With that in mind, thorough testing and investigations by governing organisations help manufacturers like Davey to apprehend the risk before it becomes an eventual health and consumable hazard.
- Unique Value Proposition: As more world-famous accreditations become awarded to all versions of Davey’s Garden System centrifugal pump, this would offer a stance of quality and safety commitment which partnered vendors and users prefer.
- Reputation: Having a catalogue of certs that is worldly in reputation helps to enhance Davey’s brand, just as our water pumps are seen to be compliant across the various territories.
SGS certificate: Two aspects of Davey’s Garden System water pump has been analysed by Société Générale de Surveillance. On one hand, the electrical study to detect any failure of insulated wiring that can cause electrocution has been tested within laboratories, and on the other, the impact of electropump’s materials onto its water pressure output to be deemed safe in real-world practice has been trialed (where irrigating use of vegetable and one’s front yard nature compartment is observed). Both of these evaluation came into clearance to show that Davey’s Garden System water pump is given the green card for end consumer use.
European Standards: The technical committee in Europe where the Garden System water pump is seen to adhere towards the mandated product constitution, utilisation wellbeing, operational efficiency, and also environmentalism in build. These four factors has been considered in combination to gain leeway into the West which Davey’s pump can be distributed, retailed, and then obtained.
Part of the key acquisition of European Standards is the item acknowledgement of interoperatability, otherwise defined as an integrative water pump merchandise that meshes well with other forms of water system inventions found in the available European countries. This is crucial as to maintain an ease of trading and to lessen the errors behind communication. A fine example would be fitting a pressure tank of another manufacturer onto Davey’s Garden System water pump, and both of these producers hold a similar stamping that is known as ‘CE‘, also defined as European Conformity.
International Electrotechnical Commission (IEC): The main and global organisation spearheading anything electrical, semiconductor-based, and relatable technologies of both paper publishing, as well as development which all of Davey’s electropumps do comply. It must be followed through as electric-type of water pumps (which includes our Garden System) will always remain in the electrotechnology ecosystem due to its TEFC motor commissioning.
Standards Australia: An independent, non-profit entity in the homelands of Davey Water Products covering all issues and maturity of every products and servicing standards found. This have since become a crucial referencing point in the Australian courts of law and also by their government when it comes to ensuring security, flawless quality and operation labelling of water pumps, which Davey is more than happy to follow through. And despite having this booster pump solely used to nourish a beautiful garden design, it is important for us to attain the Standards Australia identification for domestic support reasons. Moreover, gaining it permits Davey to sell locally.
- AS4020:2005: This sub-clause is attained to denote that any form of water contact running through the Garden System pump will always remain safe and does not pose any peril towards the human health. Moreover, microscopic studies were conducted onto the hydration source that was run through reveals that no detrimental changes was discovered, which leads to having the AS4020:2005 being given. The examination actualises all the different parts assembled onto to Davey’s Garden System, which comprise of the suction inlet, discharge outlet, other pipe fittings, coatings, seals, and even the pressure tank or digital controller as an accessorised attachment to have no effect at all, and is also recognised for its approval of drinking water standard among merchandises related to hydration.
Standards New Zealand: An official governmental division of the Ministry of Business, Innovation, and Employment (MBIE) that details technical guidelines for all centrifugal pumps to heed. With industry-specific protocols in-place, it is important to pay attention as Davey features the many pump variety for different situational use. From borewell pump, to slurry removal, deep-sea oil extraction, and even flood management, each scenarios would feature many specific requirements needed. But more importantly, having the Standards New Zealand would permit market access as demanded to increase capital share of the pump and mechanical engineering industry.
ISO 9001: A quality management system that is widely adopted by factories and recognised across most customs that pertains a controlled processing approach, and when it comes to Davey Malaysia, the production of Garden System water pump also happily respect. The ISO 9001 allows for further improvement through efficiency and effectiveness that can be obtained with continuous steps of refinement so higher quality produce of electropumps can be achieved.
ISO 14001: One of the biggest boon profiling Davey Malaysia is our cooperation with the authorities to promote a greener and a sustainable future, and this represents the subdivision of ISO as 14001 being carried out. With meticulous planning in Davey’s manufacturing of the Garden System water pump, discarded resources are carefully thought if it could be reused, reduced, and/or recycled. Staff training are instilled further to monitor wastage being disposed, while just enough raw material is supplied to create the Garden System electropump to reduce unnecessary excess. The total coalition of all eco-friendly steps drew Davey and all of our water pump to be energy-efficient – whether by our assembly line’s output or upon running a tap.
Linear And Soft Pressure Output With TEFC Motor
A light liquid pressurisation is the offering yield from Davey’s Garden System water pump. This is as soft as pressured moisture can be, as the drench considered for blooming flora becomes generated by a small-sized, totally-enclosed fan-cooling engine (or TEFC motor). Moreover, just as it’s solely for basic watering down, the Garden System centrifugal pump will have a linear volume throughout its performance.
Low maintenance: This is a priority as no other settings are needed to be configured – other than simply having the pump’s plug to be wired into the socket for a kickstart and immediate implementation.
Lesser Voltaic Consumption: The Garden System is built perpetually for simple greenhouse hosing, hence, the TEFC motor fitted-in is not only small but also galvanically efficient by using less electricity.
Tried & Proven: This is a timeless water pump technology that has been applied, used, and re-used throughout the centuries since the inception of centrifugal force and power supply. And because of this, Davey is against going against the trend to spin the wheels and reinvent a proven electropump invention.
Economical: As rugged as it can be to resist daily impact and also debris, other fittings remained as simplified as Davey can have to ensure reasonably priced lawn-based water pump.
In terms of noise level, a moderate amount of decibels (dB) will be produced upon the execution of the Garden System water pump. All power requirement for all variants of this centrifugal pump is as below:
| Product Code (SKU) | kW (P1 / P2) |
|---|---|
| SJ35-04PC | 0.53 kW / 0.37 kW |
| SJ60-08PC | 1.16 kW / 0.9 kW |
| SJ35-04 | 0.53 kW / 0.37 kW |
| SJ60-08 | 1.16 kW / 0.9 kW |
Inlet Sizing With British Standard Piping Comformity
Two varied suction inlet sizes of Davey’s Garden System water pump can be obtained:
- 1 inch (25.4mm) for the SJ35-04 and its pressure controller variant
- 1.25 inch (31.75mm) for the SJ35-08 and its pressure regulator iteration.
The stated diameters are a uniform practice that’s being used all throughout the water systems of Malaysian housing, although a pipe connector can be attached to make any flexible installment as needed to smoothly run the pump. With an inch being customary in British standard piping to draw an intake of water, a normal flow rate is accomplished under the smaller Garden System electric pump version, whereas the larger SJ60-08 variety draws in higher water reserve to make a faster and higher volumetric flow rate ideal to spurt a spray.
Upon delivery, Davey’s Garden System water pump comes with a plastic cap that is sealed onto the inlet itself. This is conducted as to prevent unnecessary debris, mud or any other transporting waste from entering and damaging the electropump.
Clean Water Only: Only filtered hydration source by Malaysian water providers can be ran into Davey’s Garden System centrifugal pump, because of its innate build-up that runs solely on clean liquids for garden and vegetable farming.
One-Direction Flow: A suction is formed as the inner impeller help to draw in water, and this flowing drench goes unidirectional only to be pressurised and flown in the discharge outlet. By achieving this stature, a potential self-priming state is realised and is further important for any water pump to prevent unnecessary cavitation and potential water hammer from forming. A net positive suction head (NPSHr) can also be described for this phenomena during this period.
304 Stainless Steel: Stronger alloy in 304 grade has been used to house Davey’s Garden System water pump. The numerical classification indicates a greater and varying mixture of chromium, carbon, nickel, nitrogen, and manganese composition, and this implicates a greater length to resist against over time rust – by the default soddening as water flows within the pump, and outwardly to fend against moisture and unnecessary dust. Besides that, this material quality is equally added for the electropump’s impact fortitude.
Volute Shell And Inner Components
Where the inlet port is built from is actually part of an elongated cylinder storing and holding every single internal components in orderly placement, and this is known as the volute casing of a water pump.
Internally, the cylinder shaping is essential for its spiral-like chamber that interchanges lower velocity into higher pressure slow and steadily, which is definite once the hydration gush enters and runs through the system of Davey’s Garden System water pump. This observation is scientifically proved and is now defined as the Bernoulli’s Principle, which is a key concept in fluid dynamics to describe how pressurisation is secured.
Directed Wetting: Much like the intake of h2o from the inlet, the volute casing is efficiently streamlined to be responsible for a continuous directional flow throughout the cycle of a water pump processing, and this shell is purposely developed to navigate hydration to prevent stammering that can damage core parts, creating cavitation and also water hammer.
Steady Water Dispersion: The sleek internal build of the volute casing is designed so to smoothly distribute hydration across the water pump’s housing, maintaining a balance of tiptop performance during the run. Another benefit out of this dispersion is the assistance to achieve a self-priming status.
Airplane-Grade Stainless Steel: 304 graded metallic alloy is also the material enclosure for Davey’s Garden System water pump, offering a rust-free agenda equivalent to airplane-bracket specification.
Venturi Effect
One small piece just after the suction inlet of this electric pump holds a small and tight plastic tubing known as the venturi. This is placed just before any dampening gets into the impeller, and its introduction imitates the ‘venturi effect‘ in fluid dynamics, creating higher pressure and velocity, but lower volumetric flow rate as a result of the overall surface area being tighter (as shown in the smaller tube’s breadth from the initial suck-in).
Glass-filled plastic-made: Plastic is the usage for the venturi tube, and this was exercised into Davey’s Garden System water pump due to two reasons:
- User-Friendly Cost: For the sake of irrigating herbs and vegetation plot, Davey’s keeping the overall costing lower by utilising thermoplastic for the venturi tube, making the Garden System water pump always affordable.
- Hydrophobic: The polymer application is considered into use as it repels water molecules from dragging and causing friction among the inner lining of the venturi tube, maintaining the velocity and pressure better with this water pump.
- Easily Replaceable: The synthetic pipe can be effortlessly replaced with anew with Davey Malaysia whenever the Garden System water pump’s venturi becomes broken. Besides that, costing remains far lower in pricing than having one in stainless steel.
Impeller And Diffuser In Garden Pump
A single phase staging body is seen in Davey’s Garden System water pump for adequate saturation. Here, the same aircraft quality alloy is chosen for the impeller rotor’s physical property to resist against direct corrosion (due to its immediate contact with flowing water). This durability is moreover preferred to withstand cavitation, which can be overall devastating to the supply of water.
Initially, liquids become accelerated before it enters the diffuser. Also known as vanes or blades, these would rotate because of the impeller’s attachment on the shaft, and then converts the flow from rotational force into kinetic energy within the water pump. All hydration slows down and is pushed outwardly before they translate to the outer walls of the volute, gaining higher pressure in the process and this is reached prior to being discharged at the outlet.
Closed Impeller Design: a sealed rotor is used to have better thermodynamics action in Davey’s Garden System water pump. This is the achievement by reducing entropy (randomised aquatic movement) while smoothening it for better execution.
Gasket
With every single parts of this booster pump in motion, the gasket remains a vital integration to lock both the volute and the TEFC motor in place. This is because h2o flows rampant and absurdly quick within that it requires a fastening between the two separate chunks, so water does not swirl and splash into the electric section of the Garden System centrifugal pump.
Vibrational-Absorbent: Another role centred to the gasket is its pivotal responsibility in absorbing vibrations as a byproduct of running the water pump. By soaking up unnecessary stress, the parts would remain closely confined and properly in-place instead of being loose over time.
Backplate And Mechanical Seal
The backplate serves as a tertiary barrier protecting Davey’s Garden System water pump’s engine from possible rinsing, and this is damaging towards the electrotechnology. As it’s the final line of shielding, this is always located just in front of the TEFC motor found, and one that’s paired with the gasket as a sealant for complete dampen-proof.
The gasket features a hole in the centre, and this is where the shaft goes through it as it’s the only link from the centrifugal pump’s engine to the impeller and diffuser ahead. As the backplate remains fixed, a structural support becomes offered to maintain every components of Davey’s Garden System water pump in alignment.
A mechanical seal will be the instrument to close the hollow circle found in the centre, which is the final point where leakage can come through in a water pump. With a rotating ring on one end being fixed to the shaft and the other section having stationery ring on the volute, fluids will not escape imminently to harm the pump’s generator.
Friction-Easing: The spinning aspect of the mechanical is set in motion whenever Davey’s Garden System water pump is in operation, and to reduce resistance, low-abrasion elements like carbon becomes chosen while maintaining its hardness. To the opposite end, the stationary seal ring is ceramic or silicon carbide for the same property reasoning that is joint by a stainless steel spring for elasticity, strength, and long-lasting action, and this keeps it to move freely inside the water pump.
Heat Transfer: Remember, to slosh down your lawn, operational work for the Garden System must be in action. Thermal expansion is inevitable as an outcome, which is why these chemical constituent is used with an awareness from Davey Malaysia’s electrical and mechanical engineers to handle searing temperatures in this electropump.
EPDM O-Ring Tightened And Washer
Stronger constitution of O-ring with the usage of ethylene propylene diene monomer, also known as EPDM, is put into the Garden System water pump. This composition is in use for its consequence in withstanding higher temperatures, which happens during the centrifugal pump’s exercise.
The O-rings are primarily tightened onto the volute cover and its shaft, and as a consequence leading to a complete part-to-part water pump’s sealing. In another finding, friction is also minimised as it behaves like a cushion between the electropump’s components.
In between the single phase impeller, a miniature flat-disc defined as the washer is suited both front and back is laid into positions, and this is used to diminish pressure evenly throughout the water pump.
