Description

These are extremely high quality and long lasting mechanical pressure switches that can turn your pump on and off in remote areas without the need for power or complex controls circuits. Suited to outback conditions, these switches are simple, reliable and accurate and perfect for a range of pumping applications.

Pump Mechanical Pressure Switch
  • Suitable for remote installations without power
  • IP66 rated with UV stabilised casing to last in the Australia outback
  • Wetted components made from 316 Stainless Steel and Teflon which suits most fluids including those with high salinity 
  • Fully adjustable between 1-15 bar (15-215 psi)
  • Suitable for loads up to 15 amps / 240v AC
  • 2 yrs warranty

A mechanical pressure switch is ideal for turning your remote solar or 240v pump on and off at pressure set points. It works without the need for power making it extremely versatile and reliable. 

A common application would see a down-hole solar bore water pump or similar, discharging water directly up a hill to a stock feed tank. The tank is a long way from the pump and there is no cabling or communication between these locations. When the sun is shining, the pump wants to run and pump water. However, when the stock feed tank fills, what turns the pump off? 

Incorporating a mechanical pressure switch in the above design is perfect as it allows the pump to be turned on and off as the tank fills. Simply fit a float valve to the tank inlet, when the tank fills the valve will close. The closure of the tank fill pipe puts back-pressure on the pipeline, increasing the pressure at the pumps outlet. 

The mechanical pressure switch can be installed at grade next to the power supply of the pump. When the pressure rises, it actives the pressure switch and cuts power to the pumps motor. 

The user has the ability to not only set and adjust the pressure at which this switch activates, you can also adjust the differential pressure at which the switch de-activates. 

This type of installation saves having to run a signal cable between the tank and the pump and offers a mechanical solution which is extremely reliable and low complexity.

The build quality in these pressure switches is exceptional and they are proven to perform well with little attention required in remote areas.
