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.

Q. Can a permeate pump and a boost pump be used together on an R.O. system?
A. Yes. See IMI 147, paragraph F, of RO troubleshooting guide.

Q. Received permeate pump without installation instructions
A. See IMI 106, Permeate Pump Installation Instructions

Q. How can a Permeate Pump be retrofitted into an existing system?
A. See IMI 119, 120, 121, or 122 for retrofitting instructions.

Q. How can the Permeate Pump be used with an RO manifold system?
A. See IMI 123, 124, or 139 (Culligan system) for retrofitting instructions.

Q. What maximum production membrane can be used with the ERP 1000? ERP 500?
A. ERP 1000 will handle permeate production of 100 gallons per day. The quieter model ERP 500 is capable of handling 50 GPD membranes.

Q. My holding tank will not develop enough pressure to supply remote locations
A. A Permeate Pump allows more water to be forced into the air bladder holding tank, thereby creating higher pressures, providing an automatic shut off valve (ASV) has not stopped the flow of feed water. See IMI 106 for description..

Q. My permeate pump is not working, because I cannot hear it clicking?
A. First, determine it is not working by removing the tube connection to the holding tank. If permeate is not being ejected from the permeate out port, then check to see if permeate water is being produced by removing the tube connection from the membrane. Finally, remove the brine connection to see if brine water is being supplied to the pump.

Q. Is there an Automatic Shut-off valve for use with the Permeate Pump?
A. Yes. The ASV 2000 was designed to allow more water to be stored in the pressurized holding tank before the feed water valve closes.

Q. Is an Automatic Shut-off Valve required?
A. We recommend using a high volume shut off valve with our Permeate Pumps to avoid “TDS creep” during startup each time a small quantity of water is produced.
