CPM146 Single Stage End-Suction 0.55kW | AQS Liquid Transfer

The Vega CPM Single-Stage Centrifugal Pump

The Vega CPM Single-Stage Centrifugal Pump is an ideal pressure boosting centrifugal pump for the transfer of clean liquids. The 0.55kW can deliver a flow up to 100L/min and pressure up to 2.6Bar. The single phase (220V) units 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.

Product Standard:

IEC 60034-1 IEC 335-1 IEC 34-1 ISO 2548

Motor:

Single-phase power supply with capacitor permanently activated. Fitted thermal overload. Insulation class: B Protection: IP44 Speed of rotation: 2850rpm Continuous duty: S1

Troubleshooting QB and CPM Booster Pumps

When all fixtures are shut off, the pump does not turn off

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.

The reset button on the flow controller has to be pressed to switch the pump on every time the pump switches off. The tank has adequate water.

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.

The pump only switches on when there is almost no pressure in the fixture.

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)

The pump indicates “failure” and does not turn on when a fixture is opened

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.

The pump continuously cycles on and off, with a few seconds or minutes delay in between each cycle.

Check for leaks in the plumbing between the pump and the fixtures.

When the pump starts or runs, the circuit breaker trips

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.

The pump was quiet when it was first installed, but it then began to produce a loud noise

Examine the motor for any signs of water that can damage the bearings.

When the pump should start, it makes a humming noise and vibrates slightly, but the fan doesn’t turn and the pressure in the fixtures is low

Ensure that the motor turns freely by hand after the power is switched off.

The flow controller’s “On” light is illuminated. The pump doesn’t turn on

Examine the electrical cable, electrical connections and protection equipment between the power supply and flow controller.

No lights are illuminated on the flow controller. The pump doesn’t turn on.

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.
