There are hundreds of different water pump models on the market, and it can be daunting.

Here we are going to talk you through how to choose the right water pump for your needs.

Firstly, you must determine your need, why you need a water pump.

Water pumps are a useful tool for a variety of residential, light commercial and agricultural tasks. A water pump can be used for:

  • Draining water (flooding, or overflow).
  • Draining and filling a swimming pool, pond, or outdoor spa.
  • Agricultural irrigation.
  • Distributing fertilisers and pesticides.
  • Construction purposes.

Next question is, how do you choose the type of water pump?

A good tip, is that all water pumps are measured in discharge capacity (GPM), vertical suction lift, and maximum head lift.

GPM Discharge Capacity is the rate of speed that water flows from the source to the discharge point, measured in gallons per minute. It provides the power to move water quickly.

Vertical Suction Lift is the vertical distance from the water source to the pump. This is important for draining a basement or deep pond.

Maximum Head Lift is the total height from the source of the water to the destination or drainage point. This provides the power to move water over a distance.

If you have any questions about this, our staff at Sunshine Coast Mowers in Mooloolaba or Caloundra can assist.

Lastly, what types of pumps are available.

Engine driven

These are pumps driven by a combustion engine, either petrol or diesel. The two primary benefits are their portability and their ability to run independently of electricity supply.

Electric powered

These come in a variety of sizes and designs to suit different purposes. These pumps can handle long running times and are often stationary units not intended for moving, such as providing a house or building with water pressure.


Jet pumps are designed to draw water from deep sources. They are typically used to draw water from bores, wells or sources much lower than the required destination. Many jet pumps are electrically driven, but engine driven models are available too.


These pumps utilise a different mechanism than centrifugal pumps. They are designed to pump thick contents such as sewage, mud, or high solid containing water.


Stationary pumps are often large and used for industrial or agricultural purposes. These are available as electric or diesel engine powered units. They are designed to move large quantities of water over long periods of time.
