For many people, the technicalities associated with pumps can be confusing and a little daunting to start with. So we hope that some of the following information will help to de-mystify pumps.
The first step in trying to get your head around these pumps is to try and understand some of the lingo. It’s important to know a bit about the following terms when selecting a pump.
External Pressure Pump – A pump that sits externally from the water tank
Submersible Pressure Pump / Sump Pump – Pump is mounted inside the tank below the water line.
Inlet – Entry point of water into the pump
Outlet – Exit point of water from the pump
Power – The pumps required electrical power to operate in Watts (w). Lower Watts equals lower power consumption and lower power costs.
Float Switch – Used mainly on submersible pumps to prevent damage from running dry. A small float used to turn off pump when water level reaches minimum. Also turns on pump when water level is high enough to safely operate the pump.
Pump Controller – Used mainly on external pumps to automate the pumps operation and protect from running dry. Pump will turn on when you open a tap and off when you close a tap. Also turns pump off when your tank is empty to prevent damage. Some controllers also vary the pumps power depending on the water supply requirements to improve the pumps efficiency. Some controllers can also switch between tank and mains water supply which is important when tank water is used to flush toilets or fill washing machines.
Hydraulic Head Height – The measurement of water pressure expressed as a Height above the pump outlet in meters (m)
Max Hydraulic Head Height – The maximum height a pump can hold water above the pump outlet with zero flow in meters (m)
Useable Hydraulic Head Height – The height at which a pump can supply a useful flow rate of water above its outlet in metres (m). 15LPM is a standard garden tap.
Maximum Flow Rate – The amount of water the pump can supply in a given time in Litres per minute (lpm).
Suction Head – The maximum Height in metres a pump can lift water into its inlet in meters (m).
Friction Loss – Available head is affected by friction loss in pipes after the pumps outlet. Long pipe run lengths, small diameter pipes and tight turns reduce head heights and flow rates of water from your pump. Use pipe diameters equal to pump outlets or larger for best results.
