About this item

  • This pump kit includes Aquatec high flow booster pump 8852-2J03-B424 with heavy duty steel base plate with damper, PSW-340 pressure switch, 110V Transformer, 4 reducer fitting 3/8" to 1/4", detail instructions
  • This pump is designed to increase the water supply pressure to a RO water system. Increase input pressure from 30-40 psi to 60-80 psi depending on the capacity of your RO system. This pump is good for under 200 GPD (gallons per day) RO systems
  • This kit is good for 1/4" OD tubing or 3/8" OD tubing since we include 3/8" to 1/4" reducer fittings for pump and for pressure switch
  • Automatic ON/OFF operation. The pressure switch would sense the pressure in the output line, so when the output line is shut off or the storage tank is full or reaches 40-50 psi, the pump would shut off, and then when you start using water and tank pressure drops, then the pump turns back ON to replenish the tank.
  • This kit DOES NOT come with the optional (ESO) Electric-Shut-Off solenoid valve, so it would rely on your existing mechanical auto-shut-off valve in your RO system to turn off the water supply when the tank is full. For most systems this kit will work fine. But if your existing shut off valve is interfering with the pump then you need to get a ESO solenoid valve with Aquatec plug, 24VAC


Note: All pumps are wet-tested by the manufacturer so there are water inside the pump head, and temporary rubber plugs are used at inlet and outlet to prevent water from coming out or dust from going in.

My property runs on well water and our pressures are somewhat low. Running the hydro logic stealth ro 150 from a faucet with the house pressures didn’t allow the ro system to reach optimal pressure. Installing the booster pump absolutely worked and allowed me to dial the pressure needed and help my flow rate greatly. Filling my reservoir doesn’t take hours now. Happy this worked.

Pressure switch was not working at all in first sample. I’m the second sample the pressure switch needed to be adjusted to meet the proper 20- 40 psi on/off range. Pressure switch can be raised (clockwise) using a tiny Allen wrench or the small bit set from harbor freight. On line documents for the pressure switch list the incorrect hex size.

This pump raise the pressure from 35 or 40 to over 100 , make RODI water at the rate the system of 150 a day was intended for. Would recommend 💯 % , buy it

It’s a little noisy. Easy to install and produces much greater flow volume to the point of use. Fast recovery time. I installed a 25 gallon product water tank and set the tank air charge to 15psig. The cut out is 45 psig, cut in is cut out less differential of 20 psig.It works quite well.

I purchased this booster pump on January 10, 2024. The item was packaged well and shipping was quick. Installation is quick and easy, but you can find lots of free online tutorials if needed.I had purchased a RODI filter system to fill my new 100 gallon saltwater tank. I connected it to my backyard water hose and, to my surprise, the water just dripped out of the RODI line, but was running fast from the waste water line.It took over a week to fill my 100 gallon fish tank, with the RODI unit from the backyard water faucet. I tried from an indoor sink faucet, but that produced no water at all. I would estimate the ratio between RODI and waste water from my water hose is about 1:4. I ended up with 100 gallons in my fish tank, and at least 400 gallons of waste water. That much waste water is just not acceptable.After some research I found this little booster pump.I went from a 1:4 ratio to about 1:2. I use the waste water for my pet’s water bowls to avoid as much water going down the drain, and it’s healthier for them than our sink water. Others have mentioned using it to water their plants.My only con is that it hasn’t even hit one year and the motor has gone out. I initially thought it was the power cord thinking maybe it got wet and burned out, so I bought a replacement power cord. I can hear a faint buzzing from the motor but it is not “boosting” the water. My guess is the motor burned out.Although my item stopped working just short of a year, I am purchasing this same item to replace it. Here’s why: This booster saved me a lot of time, and probably a small fortune, in just 11 months. Less waste water and a lower water bill makes this booster one of the smartest purchases I’ve made since starting my saltwater tank. If you own a fish tank you know that you are always making water, and a lot of times you have to make a lot of water in a pinch! I’m just trying to not go broke in the process.I recommend this booster pump to anyone looking for a way to save time and money in this very expensive hobby. Happy reefing!

Installed for a month now. While you can hear it running, it's not intrusive. Really helps with daily volume, should have installed sooner.

Installed pump before stage 1, pressure switch after stage 5, took like 30 mins to pressure up to 40psi, easily adjust it higher. It's not as loud as I thought it would be based on reviews. It's similar to my 45-50 dB dishwasher when it runs the drain pump.It's on 4 rubber feet. Have it sitting horizontally next to the 5 stage filters in an older cabinet. It could easily be quieter with a higher quality cabinet.

Easy to install and worked great, completely resolving all of our low water pressure issues. However, after only 11 months of service, the pump died.
