The QB Peripheral Vane Pump is an effective, reliable, and energy-efficient unit. It has a flow rate of up to 35 liters per minute and is available in a combo that includes a flow control switch and lead out cable. When the pressure drops, this switch automatically starts the pump, then turns it off when there is no flow. This product is issued with a Letter Of Authority.

Troubleshooting QB and CPM Booster Pumps
- Retest after closing the valve that is directly attached to the pump’s outlet side.
- Verify the piping between the pump and the fixtures for leakage.
Adjust the screw at the top of the flow controller so that the cut-in pressure (the pressure at which the pump switches on) is lower than the cut-out pressure (the pressure at which the pump switches off). Turn this screw counter-clockwise, toward the minus sign.
Adjust the screw at the top of the flow controller so that the cut-in pressure (the pressure at which the pump switches on) is higher than before. It is recommended to leave at least a Thar difference between the cut-in pressure and the cut-out pressure (this is the pressure at
which the pump switches off)
Examine the water supply tank to see if it is or was empty. Remove the air from the pump casing and push the flow controller’s “reset” button.
Check for leaks in the plumbing between the pump and the fixtures.
- Confirm that the circuit breaker rating is correct according to the pump size
- Look for any traces of water that could cause a short circuit in the motor.
- Check all electrical connections for short circuits and exposed wires.
Examine the motor for any signs of water that can damage the bearings.
Ensure that the motor turns freely by hand after the power is switched off.
Examine the electrical cable, electrical connections and protection equipment between the power supply and flow controller.
- Examine the electrical cable, electrical connections and protection equipment between the power supply and flow controller.
- Ensure that other electrical equipment turns on when plugged into the same outlet as the pump.
