About Aquatec Booster Pumps
Aquatec’s original product, and still the “global standard” in booster pump technology, providing reliable inlet pressure for efficient membrane utilization. These pumps are capable of continuous duty and are effective for recirculation based applications as well. They are ideally suited to work with hydro-pneumatic storage systems but are compatible with most hydraulic shut-off valves also. This type of Aquatec Pump is commonly used with one or more of our flow control components including: pressure switches (PSW Series), tank level controllers (TLC Series) or electronic shut-off valves (ESO Series).
Typical Applications for Aquatec Booster Pumps
-
Water Treatment/RO
-
Carbonation Systems
-
Misting Systems
-
Alternative Energy/Solar
-
Medical Labwater
-
Laser Cooling Systems
-
Fuel Cells
Technical Specifications for Aquatec RO Booster Pumps
-
POWER: Safe operation with low energy (24 watts), low voltage (12-24V) motors. Can be used with compatible transformers (100VAC, 120VAC, 230VAC), to be ordered separately.
-
ENVELOPE DIMENSIONS: Approximately 3”x 4”x 7”, 6 lbs.
-
MOUNTING: Our patented “flex-mount” baseplate significantly dampens vibration and reduces noise. Other steel mounting baseplates and “universal” baseplates are available at no additional cost. Pump performance may be affected by location and positioning.
-
CONTROL OPTIONS: Internal Bypass (20-200 psi)
-
FITTINGS: Available options include built-in 3/8”, 1/4”, or 5/16” John Guest half cartridges
Aquatec Booster Pump FAQ
Q. The CDP continuous duty pump, runs continuously
A. See IMI 156, Automatic Shut Off Valve’s effect on the PSW’s shut off ability
Q. The pump that delivers water from the holding tank to the refrigerator is noisy
A. The pressure switch controlled demand delivery pump is probably delivering more water than the icemaker can accept (usually about 1/4 gpm at 35 psi), and is momentarily reaching its shutoff pressure. Use a lower flow pump, and add an accumulator between the pump and refrigerator if necessary. Open the “high voltage drinking water delivery pumps” selection chart, section A, for recommended choices.
Q. What effect does feed pressure have on the tank/faucet pressures?
A. None. The flow of water to the membrane will increase, but 80 psi pump discharge pressure will not change due to the preset by pass pressure.
Q. What effect does higher by-pass pressures have on tank/faucet pressures?
A. Since the pressure entering the membrane has increased, so will the pressure exiting the membrane, at the expense of flow, however.
Q. What is the membrane rating based on?
A. Based on 95% rejection of TDS levels at 600 ppm and 60 psi membrane feed pressure, in a 70 degree F ambient environment.
Q. The boost pump output pressure is only 60psi?
A. Assuming you have not adjusted the by pass setting, you may be using a membrane with a permeate production higher than the pump can supply. Either switch to a higher flow pump, or go to a lower rated membrane.
Q. Are low feed pressure shut off switches (LPS) available?
A. The LPS comes with the appropriate wire harness, but a tee with a 1/8” NPT female center port is not provided.
