Submersible Pumps
We have a comprehensive
range of submersibles
to suit all applications.
Whether it is for a low flow bore or a high volume irrigation project we can provide a quality system to suit your needs and budget. As stockists of Lorentz, Waterboy, TuHorse and Icon solar pumps we can offer a range of solutions and give you a choice of brands that are all a backed by a 2-year warranty. We also supply and service Grundfos, Sun Mill, Franklin and Sun Pumps.
Our submersibles can be setup to go into a dam, bore or even a tank if required. We provide all components required to set up your pump correctly including dam floats, downhole components for bores, probes, float switches and all other accessories.
A submersible pump is a pump that is designed to be fully submerged in the fluid that it is pumping.
Our submersibles pumps are made up of of two key components, the motor and the pump end. The pump end is bolted on to the motor which spins the shaft or rotor of the pump end.
In solar pumping there are two main types of pump ends. These are helical rotor and centrifugal. Both pumps have their advantages but helical rotor pumps generally require less power to push higher heads than centrifugal pumps, but are not really designed for flows over 5,000LPH.
Helical pumps are comprised of a rotor and rubber stator and are commonly referred to as "worm drive" pumps. Centrifugal pumps are made up of multiple stages and the size and quantity of the stages will determine flow and maximum head.
There are two types of motors available for solar pumping and they both have some advantages and disadvantages.
These are DC brushless which requires a controller on the surface to operate and DC/AC motors where the controllers are encapsulated under the motor.
The main brands we use are DC brushless due to the high efficiency and our preference to have a controller on the surface. Having the controller mounted at the array gives our clients more flexibility with pump control and the ability to add multiple inputs to control the pump including pressure sensors, water meters and low-level probes. Lorentz controllers also allow data logging so you can monitor your pumps performance. The main disadvantage of DC brushless systems is that they can't run directly off a generator or AC connection. If this is required a separate AC/DC inverter needs to be purchased. Our motors are both water and oil-cooled depending on the brand.
AC/DC motors are still highly efficient and can usually be adapted to plug straight into a power source without the need of a controller. A controller can be added to the system where probes or switches need to be added to the system to help operate the pump. With the controls/inverter in the motor the system will sense whether there is an AC or DC power source so can be easily changed over as required.
