Booster Pump Control - Double Chamber (BPC)

Features

- Suitable for most pumping applications including suction lift and low differential head
- Prevents pump starting and stopping surges
- Built-in non-slam mechanical check reduces surges on loss of power
- Separate opening and closing speed controls


The 106-BPC and 206-BPC booster pump control valves are installed in-line, directly downstream of the pump discharge.


The pump control valve is normally closed and on pump start-up, a pilot solenoid is energized to open the valve, at a rate governed by the opening speed control. When shut-down is required the pilot solenoid on the valve is de-energized to commence closing. The pump is kept running while the valve slowly closes. When the valve is almost fully closed and flow is virtually zero, a stem mounted cam triggers the limit switch to stop the pump.
In the event of a power failure, the built-in mechanical drop check closes immediately when the flow stops, independently of the valve position. Surges are minimized by closing the valve before reverse flow occurs.
