Vortex sump pump identification
Selecting the proper submersible sewage or drainage pump is simplified with Davey’s clear model identification system.
Each model name conveys specific performance and configuration information, helping installers and engineers quickly identify the right fit for any water pump system.
- Prefix “D” or “DT” – Indicates a Davey vortex drainage pump, with “DT” denoting a three-phase electric motor.
- The following numbers represent the approximate motor output in kilowatts, indicating the pump’s power and pressure capacity.
- Suffix “V” – Identifies the vortex impeller design, optimised for pumping soft solids and grey water with reduced risk of clogging.
- Suffix “A” – Denotes an automatic model equipped with a standard float switch, which activates the pump based on the water level.
- Suffix “AGMA” – Refers to compact automatic models fitted with a vertical float switch. This internal float design is ideal for narrow sumps or confined pits, where space is limited and a traditional tethered float cannot move freely.
Thus, the D75VA is a 0.75 kW single-phase vortex pump, excellent for household sump drainage or wastewater transmission. Meanwhile, the DT37V is a 3.7 kW, three-phase pump designed for industrial wastewater pits or stormwater systems that require higher capacity and pressure.
Attachments
HO7RN-F oil-resistant power cable
Safety and reliability extend to the power supply. Each pump is equipped with a 10-metre HO7RN-F oil-resistant power cable, designed to withstand exposure to moisture, oil, and chemicals commonly found in basement pits, marine sumps, and industrial wastewater systems.
In addition to preventing abrasion and fatigue during installation or maintenance, the heavy-duty rubber insulation guarantees flexibility even in cold temperatures.
The three-phase units have bare wire leads for simple connection to control panels, whereas the smaller models come with a moulded AU plug. This cable design ensures steady electrical performance in wet environments, providing the pump’s submersible motor with consistent and safe power delivery, a crucial feature for continuous water transfer, drainage, and wastewater pumping tasks.
Sand slinger lip seal
A small yet vital component of every Davey submersible pump is the sand slinger lip seal, which prevents abrasive particles from entering the motor chamber. It serves as a barrier between the impeller housing and the mechanical seals, shielding internal parts from silt, grit, and fine debris that are frequently found in storm drains or grey water systems.
This additional protection prolongs the life of the motor bearings and seals in underground installations or construction pits, guaranteeing smooth performance and thereby reducing the need for frequent maintenance. The Davey centrifugal submersible pump is a reliable option for long-term drainage and groundwater management due to its double-seal system and multi-layered protection against wear provided by the sand slinger.
Float switch (compatible for automatic control)
The Davey vortex sump pump line includes automatic water level management. The “A” suffix models have a tethered float switch that stops the pump at a safe low level and turns it on when water rises. Compact models with the suffix “AGMA” feature a vertical float switch, making them ideal for small pits with limited space. By preventing dry running, these devices lessen impeller and motor wear.
This automation ensures that the submersible drainage pump runs only when needed, conserving energy and prolonging the lifespan of stormwater pits, septic tanks, or foundation sump pumps.
Slide rail kits for easy and safe installation
Davey slide rail kits are purpose-designed to simplify the installation and removal of submersible pumps from pits, basins, or tanks. They enable maintenance teams to easily lift the pump out without unbolting the pipework or entering the pit, ensuring safer and faster servicing. Available in 50 mm, 80 mm, and 100 mm nominal bore sizes, these kits are designed to suit specific vortex sump and sewage pump models, typically those that are heavier or installed in areas where frequent cleaning or inspection is required.
Constructed in both standard and 316 stainless steel for superior corrosion resistance, the range includes the SR50, SR80, SR100, and SR150 models, with stainless steel options available as SR50SS, SR80SS, and SR100SS.

Corrosion-resistant 304 stainless steel construction
Material selection is the first step towards durability. Every vortex sump pump’s motor shell, shaft, handle, and fasteners are composed of 304 stainless steel, which provides exceptional corrosion resistance even in underground, marine, or oil-contaminated environments. This robust design ensures long service life and continued performance, even in harsh environments such as concrete pits, foundation drains, or fuel catch basins.
In addition to maintaining the structural integrity of the pump, the stainless-steel parts offer a clean, appealing surface that is impervious to wear and corrosion. Whether installed in a residential sump or a commercial wastewater system, this corrosion-resistant build ensures each electric motor pump remains reliable year after year, even under continuous submersion.
Specialised impeller design for efficient flow
The open or semi-vortex centrifugal impeller, the core of every Davey vortex sump pump, is designed to transport water and soft solids effortlessly. The vortex design, in contrast to traditional impellers, produces a whirlpool motion that keeps material suspended and avoids clogging at the impeller’s eye. Constructed from polycarbonate in the smaller pumps and cast iron in the larger models, it resists wear while maintaining consistent performance.
This design is particularly effective for grey water, drainage, or light slurry applications where fibrous matter or sediment is present. The result is a robust centrifugal water pump capable of continuous operation in basement pits, storm drains, and construction sites with minimal maintenance.
Double mechanical shaft seals in an oil bath
To ensure long motor life and protection against leakage, the medium and large-sized Davey vortex pumps feature double mechanical shaft seals (smaller models have single seals) housed within a lubricating oil bath. The pump-side seal is made from silicon carbide and ceramic, while the motor-side seal uses carbon and ceramic, providing a strong defence against wear and ingress of water or grit. The oil bath reduces friction and disperses heat, keeping the electric motor cool during prolonged operation.
This system is crucial for reliability in basement drainage, construction dewatering, and industrial waste applications where continuous operation is standard. The result is enhanced hydraulic performance, extended service intervals, and assurance that the pump can withstand demanding, high-duty environments.
