Features
E/One's WH483/WR483 grinder pump station consists of three Extreme series grinder pumps inside an open wetwell tank. The grinder pumps, motor controls and level-sensing are integrated into a compact unit, easily removable for service.
- The WH483 is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
- The WR483 is the “radio frequency identification” (RFID), or “wireless,” model that uses wireless technology to communicate between the level controls and the motor controls.
The tank is made of tough, corrosion-resistant polyethylene. Designed specifically for low pressure sewer applications, the optimum tank capacity of 486 gallons provides ample storage. A single WH483/WR483 can accommodate flows of up to 5000 gallons per day.
Stations are available in several heights to accommodate various burial depth requirements. See drawings for more information. E/One requires the installation of its stainless steel UNI-LATERAL to prevent backflow from the sewer system from entering the grinder pump station.
