Multistage Pumps efficiently achieve high pressure & flow at lower power usage with very quiet running.

This pump is suitable where there are Low Pressure Cylinders/Tapware  or Small-Medium Size Homes: 1-2 bathrooms.

Pump & Purify Multistage pumps have been constructed to a proven design, using high quality metal components, and exacting manufacturing standards.

Use Multistage Pumps in pressure systems delivering household water, irrigation, washing facilities, feeding troughs and many other applications.

We recommend that the pump and controller are plugged into a Belkin (or similar) Surge Protection device. RCD's in the power board may not provide sufficient protection from brown-outs, black-outs and power surges.

We also recommend that a pre-filter is installed inline prior to the pump suction to avoid debris being sucked into the impellers and causing damage.

Control Variations Available

• Bundled with an Italian made Watertech Press Controller for automatic on/off operation. We recommend Controllers are used in simple applications without significant ground elevations where pressure adjustment may be required. We recommend this is installed with a Belkin Surge Protector to protect the controller. You can purchase these here.  2 Year Warranty.
• Bundled with a quality reliable Chinese made Press Controller for automatic on/off operation. We recommend Controllers are used in simple applications without significant ground elevations where pressure adjustment may be required. We recommend this is installed with a Belkin Surge Protector to protect the controller. You can purchase these here.  2 Year Warranty.

• Two Bundles available with a mechanical pressure switch and pressure tank. Choose an 8L tank to avoid pump cycling from drips and leaks.  Or choose a 18L tank for quick use such as toilet flushing, hand washing preventing pump cycling.  Mechanical Pressure Switches are useful in applications which require pressure adjustment to accommodate ground elevations or other specific site requirements. Pressure Switches must be used in conjunction with a Pressure Tank.
