The iSpring PMP5 is a perfect option for anyone looking for only a replacement pump without the other components. It’s basically only the pump and a highly reliable one for that matter.
The PMP5 is a top-quality booster pump from iSpring that’s more than capable of increasing your RO system input pressure which in turn will increase water production and purity.
It has the capacity to raise the psi levels of the input water pressure going into an RO system from as low as 30 psi up to a maximum of 110 psi. It works well with 50 GPD to 100 GPD RO systems which cover most of the residential and under-counter/sink RO systems.
As for the installation, this one is pretty straightforward. The ports will accept any ¼” tubing. However, it’s a very basic pump, so you will need to purchase additional parts like the DC power adapter and the power socket for connecting the pump to the power adapter.
The pressure switch is also not included, so you might also need it in case you are installing the pump for the first time. It will generally work with all the other components of your existing pump in case you are installing it as a replacement pump.
