Method of Identification
The Rainwater Harvesting System pump features a serialisation that begins from:
1) An alphabetical order named RBP, which is an abbreviation to define ‘RainBank Pro’ pump skid.
2) This is then followed the nominal flow rate of Litre Per Minute (lpm), and in this example, 90 is the capacity offered by this version of the rainwater harvesting system.
3) What is followed up after the numerical figures of the nominal flow is then met with the Vertical Multistage water pump variant. In this situation, the image example that characterises the method of identification shows that a Vertical Multistage water pump has been fitted in.
4) The last character that represents the pump build-up is an ‘A’, which refers to ‘Automatic‘ or a Backwash Flush.
Identification also supports engineering diagram, flow chart, and process documentation for building design, farm, school, commercial project, or industrial installation planning.
In Davey Malaysia’s Asian catalogue, slight configurable changes can be seen throughout the rainwater harvesting system’s identifier code. The pump skid goes as followed:
1) MLRBP, as before, represents the RainBank Pro pump with an inverter. The inverter, or variable-frequency drive (VFD), is designed to encourage energy-savings potential by enabling the intended number of impellers according to the given status of pipes in-the-use.
2) After the alphabetical order, comes two-digits of numbers that represents the nominal capacity using BEP in metre cube per hour.
3) After the dash, a small digit represents the number of stages found.
4) Lastly, M3, as found from the image as the rear end of the serialisation signifies the number of phases.
Attachment
Pressure Tank
The system includes an 18L pressure tank constructed from powder coated mild steel.
This component stabilizes hydraulic pressure during pump operation, reduces short cycling of the electric motor, and maintains consistent water delivery during demand fluctuations.
It acts as a small pressure vessel within the centrifugal pumping cycle to improve mechanical efficiency and extend system lifespan.
Torrium2 Pressure Controller
The system incorporates an automated control management system housed within a control box enclosure.
The controller manages rainwater prioritization, mains water changeover, low tank level detection, pump fault response, and power loss protection.
Indicator lights allow easy system monitoring, clearly displaying operational status and selected water source.
This integrated control system ensures seamless operation within commercial water treatment and process system installations.
Skid Mount
The RainBank PRO is factory assembled, fully tested, and mounted on a galvanized steel base plate, forming a skid-mounted package.
This skid mount configuration supports simplified installation, quick integration into site piping, and efficient connection to rainwater tank, mains supply, and distribution valve systems.

This ensures seamless changeover between filtered rainwater supply and mains water supply when tank levels are low. The solenoid valve plays a key role in maintaining uninterrupted water service in commercial buildings.
Float Level Sensor
The system includes a low-level float switch (FS750-10 with 10cm cable) to detect rainwater tank levels. This component ensures automatic switching to mains water when rainwater storage is insufficient. It supports reliable integration within a rain catchment system, water catchment system, and sustainable drainage system.
Pressure Switch
The system utilizes an independent pressure switch in combination with a float switch.
The pressure switch monitors system discharge pressure and activates or stops the pump accordingly.
