The Orange Pumps PressMatic and MassControl switches are easy to install, reliable and functional. When the pressure drops to the “cut in” pressure the switch automatically turns the pump on. The switch turns the pump off when the fl ow stops. Pressure fluctuations are reduced as the pump does not cycle on and off during demand.

Details

The Orange Pumps PressMatic and MassControl switches are easy to install, reliable and functional. When the pressure drops to the “cut in” pressure the switch automatically turns the pump on. The switch turns the pump off when the fl ow stops. Pressure fluctuations are reduced as the pump does not cycle on and off during demand.

The switch protects the pump from “Loss of prime” when there is no water from the supply. When there is no fl ow and no pressure the pump is turned off protecting internal components from heat damage

As there is only a small amount of water draw off from the inbuilt diaphragm a dripping tap or leaking pipe can cause the switch to turn the pump on. A gate valve can be installed on the discharge port of the switch to isolate it from pressure drops and to check if there is a leak. A pressure tank can be installed down fl ow from the switch to increase the water draw off.

A replacement electrical board is available for the PM10, PM15 & PM20 models. It is easy to install with just three screws connecting it to the body of the switch, the plumbing does not need to be touched and plug and play electrical wires are attached. Model is PM-CB.

The PressMatic and MassControl switches are not recommended on power generators or in areas of poor power supply. Electrical surge protection can be installed for protection against power fluctuations.

High Volume Bypass installation

For applications where large a volume of water is required the MassControl can be installed on a separate, connecting delivery pipe. The main delivery pipe can supply the volume with no restrictions from the switch, while the MassControl can be installed on a smaller separate delivery pipe to monitor the pressure and fl ow. A check valve should be installed on the suction line to prevent back fl ow through the bypass pipe.

Note: PressMatic is compliant with Australian safety standards as tested by SGS 1/080941
