Aquatec Non-Electric Reverse Osmosis Permeate Pump | ERP-500

Aquatec ERP-500 Permeate Pump Retrofit Kit

This increased pressure allows the RO membrane to perform as if within an atmospheric tank system.

Use of a Permeate Pump improves membrane life, system performance, and provides other important benefits as detailed below. With an easy to use "retrofit kit" (snap-on mounting bracket & 10-ft. of tubing), the Permeate Pump can be incorporated into almost any existing RO system. Proper installation requires horizontal mounting (i.e. with both outlet ports in the highest position) to allow any trapped air to be purged automatically.

Features

• No electricity required, powered only by hydraulic energy normally lost to drain.
• Improves water quality by insuring membrane efficiency.
• Improves membrane life, prevents "TDS creep".
• Decreases product tank "fill time" by up to 65%.
• Reduces drain wastewater by up to 80%.
• Increases product tank pressure (up to 95% of feed pressure).
• For all membranes rated up to 50 GDP.
• Effective for inlet water pressures as low as 30 PSI.
• Compact size for easy installation.

Aquatec's original Permeate Pump (ERP1000) is a simple, yet revolutionary, device. Powered only by the hydraulic energy of brine water usually lost to the drain (i.e. no electricity required), the Permeate Pump forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure. These pumps dramatically improve the efficiency of R.O. water production, reducing wastewater by up to 80%. In other words, if your current system requires 10 gallons of tap water to produce a gallon of pure water (10:1), adding a Permeate Pump should reduce this ratio below 3:1. Permeate Pumps can also bring storage tanks up to line pressure and then shut the system down when these tanks reach capacity, eliminating the need for a hydraulic shut-off valve. Other benefits include higher delivery pressures, faster R.O. water production, superior water quality, and extended filter/membrane life. Our newest Permeate Pump (ERP 500) is specifically designed for residential applications (less than 50 GPD) where overall system noise is a key concern. The ERP 500 includes a specially designed insert which helps the system operate in near silence, eliminating the occasional clicking or gurgling sounds that can otherwise occur. Both the ERP1000 and the ERP500 can easily be retrofitted to upgrade existing R.O. systems.
