Best Reverse Osmosis Booster Pumps

Having a reverse osmosis system in your home helps ensure that the water you’re drinking is free from chemicals and other contaminants. But in order to make the most out of it, you need strong water pressure going into the system. This is where booster pumps come to play. 

In this article, I’ll share with you the best reverse osmosis booster pumps available today. They were chosen based on how fast they can pump, how well they’re made, and how convenient they are to use.

The Best Reverse Osmosis Booster Pumps

Best for 100 GPD RO Systems

For systems that only produce a modest amount of permeate water up to 100 GPD, you need a pump that’s just the right size. The Aquatec 6800 booster pump is a solid piece of equipment that’s built with high-quality construction and world-class technology. 

It’s super quiet and is just the right price. It comes with an AC to DC transformer and a pressure switch to automatically control pump operation. 

Best for 200 GPD RO Systems

If you have a more demanding system that produces up to 200 GPD of permeate water, then you need a pump that can keep up. The Aquatec 8800 booster pump packs all the important features and accessories of the 6800 but with extra power so you can fill your tank faster. 

It’s not exactly as quiet as the 6800 but it’s manageable if you use proper installation techniques. With its output though, for such a small pump, it’s really hard to complain. 

Best for refrigerators and ice makers

A demand/delivery pump is installed after the reverse osmosis unit. It’s meant to move water from the storage tank to where it’s needed like a faucet or an ice maker. This Aquatec pump delivers 60 psi of water to where it’s needed for up to 0.7 gpm. 

No longer do you have to wait forever to fill up water for your needs with a reliable pump like this. It’s very easy to install and can last for a very long time if used with care.

Best for Aquariums

Like every living being, fish and corals thrive in healthy environments. This means no chlorine or other chemicals and just the right amount of nutrients. Using reverse osmosis systems allows you to have high purity water that you can control depending on your aquarium’s needs. 

The Aquatic Life Smart Buddie booster pump was made exactly for that. It boosts the pressure of the incoming water significantly to improve system efficiency producing less wastewater and more clean water for your needs.

Buyer’s Guide

Features 

A fully-featured pump that has reliable automatic control is one that you can count on every time. The switch, the motor, and the pump itself must have features that let everything run smoothly and without issues.

Build Quality 

Good quality RO booster pumps are made of high-quality materials and construction. It must not have any obvious design flaws that would break the pump after a few months of use. Since the water will be used for drinking, it also has to be made of corrosion-resistant material that’s durable enough to last for years to come.

Price

The whole pump assembly should be reasonably priced for its usage. It doesn’t make sense to have a very expensive pump if it’s not for industrial or medical purposes. 

Why do I need an RO Booster pump? 

Typical water pressure in homes is around 40 psi. When someone opens a tap, that might decrease significantly. It might be okay for most uses but it’s not exactly ideal for a reverse osmosis filter system. 

The system relies on pressure to push the water through the membrane. Without enough of this push, the output of the system will suffer. The amount of waste water will increase while the permeate will decrease. 

What is an RO Booster pump?

A reverse osmosis booster pump increases the pressure of the water being supplied to the whole system to increase both output and efficiency. It’s installed right before the filters to allow water to pass through the RO system effectively with enough pressure left to charge the air chamber of a storage tank. 

How does it work?

A booster pump has a motor that causes a reciprocating motion of a diaphragm. This movement sucks a fixed amount of water in one stroke and sends it to the outlet in another. The discharged water is pressurized by that action and can now easily pass through the filters where the impurities are removed. 

What is the difference between a booster and a permeate pump?

A booster pump is typically installed at the inlet of the system to improve the amount of permeate produced compared to the amount rejected. The permeate pump, on another hand, is installed at the outlet of the filters. Its purpose is to push the permeate water to the tap or a storage tank using the pressure energy left in the reject water that would otherwise have been wasted.

Conclusion

Getting a pump for your RO system is a great way to make the most out of it. Saving you a bit more water and producing you even more. 

They’re not all the same though, you have to find one that fits your system the best.
