High Pressure Water Pump
Description
Quality 12V/24V water pumps capable of generating high pressures. Ideal for a range of pumping applications such as spraying, misting, reverse osmosis and much more.
High-Pressure DC Water Pumps 100 PSI, 160 PSI or 200 PSI Options
High quality reliable low voltage water pumps capable of generating high pressures. Available in a range of flow rates and pressure ratings these pumps have a multitude of uses and applications across many industries.
These pumps are supplied with an integrated pressure switch in the pump's discharge. The pressure switch is adjustable and allows the user to vary what pressure the pump will shut off at. This feature is great for those using the pump for example in a pressure washer application when the spray guns trigger is released, the pump automatically shuts off saving power and also protecting the pump.
These diaphragm style pumps are corrosion resistant and are also excellent at self-priming up to 2.7m vertically. Easy to use and install with a range of fittings supplied with the pump. The pump is lightweight and easily portable to job sites or can be permanently installed in your vehicle, motor home, trailer or boat.
Popular in a range of industries and applications including water transfer, pressure spraying, on-board boats and ships for water filtering and treating including reverse osmosis and desalination. Agricultural and farming applications for stock water in remote locations as well as commercial misting and cooling uses.
Pressure Pump Size Selection
When choosing a pump, bigger is not always better. These diaphragm pumps run a fixed motor speed and can be considered to be constant flow pumps (positive displacement). This means the pump will flow at very close to the referenced flow rate assuming the voltage to the motor is kept constant.
As an example, when making your selection, if you want a pump to spray weeds with poison, a common order we see is the SPHP200L, as people think they need the 200 psi pressure. This model pump flows about 10L/min, is which a fairly high flow rate when spraying poison. If you're using the pump with a small hose and spray lance, the pump could be working hard to force this flow rate though the nozzle. As a result, the pump may reach 200 psi pressure at the outlet which will cause the pressure switch to activate and turn the pump off. This pressure quickly reduces as the fluid passes the nozzle, so the pump reactivates. The operation cycles in quick succession and presents as a pulsing pump operation. What is actually happening is the pressure switch is constantly working to make and break the circuit. The switch will get hot and eventually burn itself out. A better choice may have been the SPHP160 or SPHP100 with flow rates closer to 5L/min.
The point is to understand any restrictions you have in your service such as a spray nozzle and match the pump to the system as much as practical and this will help the equipment to last.
