Pumping station Wilo-Jet HWJ with a hydraulic accu
Application
Self-priming stations Wilo-Jet HWJ used for automatic water supply at home and cottages from a shallow reservoir if the water is at a depth of no more than 8 m.
Wilo-Jet HWJ automatic pumping stations are units with a pump, designed to supply water and maintain the required pressure in the system.
The pumping station includes a self-priming pump capable of supplying water from the depth, as well as a relay pressure and pressure tank.
- Water supply systems.
- Watering.
- Irrigation and irrigation.
- Water supply from wells and deeply located reservoirs.

Device and principle of operation
Automatic pumping station (fig.) consists of a surface centrifugal self-priming electric pump, accumulator, pressure switch, pressure gauge and connecting fittings. The electric pump consists of the pumping part and the electric motor, which are mounted on the adapter flange.
- The pumping part is a cast iron or stainless steel casing, an impeller made of brass and built-in ejector.
- Electric motor - asynchronous, closed type with external ventilation. Installed on the electric motor terminal box, which contains the capacitor and terminal blocks for connecting the electric motor to power cable.
- The hydraulic accumulator is designed to store water under pressure. Consists of a reservoir with a replaceable membrane made of food-grade rubber and has a pneumatic valve for air injection.
- The pressure switch serves to automatically turn on and off the pump, depending on the water pressure in system.
- The pressure gauge is designed for visual control of the pressure in the system.
Installation and commissioning of pumping stations
Before installing the electric pump (automatic pumping station), it is necessary to choose the correct installation location. It is recommended to install the electric pump either indoors or outdoors on a horizontal platform, in well ventilated and protected from bad weather.
