400GPD Domestic RO Pump | 400GPD Domestic RO Pump
Advanced booster pump and power supply, which is produced for 400 GPD RO systems. This pump is designed to function with most standard unpumped RO systems. Supplied with 1/4″ push-fit pipe fittings.
As you may be aware, that RO water filter output is dependant upon good water pressure and water temperature. Here in the UK, the tap water temperature is quite stable, but the mains water pressure can vary from a low 20 to a high 80 psi (1.5 – 5.5 bar). Most RO systems do require 50 psi to operate well. If you have an RO system and the output is extremely low, you may need a booster pump.
Booster pumps will dramatically improve the amount of water produced by your RO water filter. As a rule of thumb, if you can provide the right pressure and volume of water for your system, you should be able to achieve approximately 50 to 60% of the rated membrane output.
Membranes are tested at 23 ºC, and for each ºC below this temperature, you lose around 4% output. Many sellers on the internet state one of their pumps will ensure you get the stated output from the membrane, although they do not consider the real-world technicalities of the product. We would rather provide you with the information that we know to be accurate.

This pump is not designed for 24/7 continuous operation, meaning it should be rested for 15 to 30 minutes every 4 hours
Notice: Please ensure that you select the correct capacity pump for your reverse osmosis system, for example, a 100gpd pump for a 100gpd unit.
If the incorrect pump is selected, you may experience water quality and production issues with your reverse osmosis system.
Pump care:
Do not run a pump for more than 4 hours continuously.
This is to stop the pump from overheating and becoming damaged.
To achieve this, we would suggest installing some form of the timer, so that after 4 hours of operation the pump has a 15-30 minute break. This will enable the pump to cool down.
The warranty for the pump would be null and void if no timer is used. If there is an issue with the pump we would ask for evidence of a timer being used to allow the item to be covered by the warranty
Do not allow the pump to run dry (without an active water source) as this will damage the pump.
The only time that we would suggest running the pump without an active water supply is if you have a low-pressure switch wired into the pump, as this will automatically switch the pump off when the incoming water flow is turned off.
The warranty for the pump would be null and void if used in an application of running dry without a low-pressure switch- We will ask for evidence of the use of a low-pressure switch to receive a warranty replacement of the pump
We suggest that the pumps are permanently mounted. This is to stop any potential for the pump to vibrate and become damaged
We will ask for evidence of how the pump is mounted for the item to be covered by its warranty.
