Check the listing for details. AQUATEC 8800 water pressure booster pump Euro220V transformer CDP 8852-2J03-B424. Condition: New. Listed at 129.95 USD. Aquatec Pressure Boost pump CDP 8800 series (High flow) 3/8" and 1/4" fittings 220V/50HZ transformer Including: pump + transformer 220-230V/50Hz + both 3/8" and 1/4" fittings Aquatec model # 8852-2J03-B424 Filter Direct part # HF-88-220V (pump + transformer+ fittings) Condition: brand NEW Made in USA This water booster pump is to boost the input water pressure. It is usually used to increase the input water pressure for Reverse Osmosis systems. (boost pressure to 60 to 80 psi) This pump is suitable for RO systems that is 100GPD to 200GPD * This listing is for the pump+ transformer 220-230V/50hz European plug + 3/8" and 1/4" fittings. We have another listing that has 110-120V/60Hz US plug pump +transformer. We also have another listing that has pump, transformer, solenoid valve and pressure switch, or just the pump without transformer. Benefits of using Booster pump for Reverse osmosis systems · For RO systems, an increase in input pressure means an increase in water production and water purity · RO systems will run more efficient, and have less drain water. Since it uses pressure switch and solenoid valve to turn on/off the water input, it can turn-on and turn-off more accurately than the mechanical auto-shut-off valve. · If you use large water container or open water tank, you can use float switch or level switch to control the operation of the pump as well. · The transformer included in the package is strictly for plugging into European 220-230V/50HZ electrical outlet.. Specifications: Booster Pump: Boost pressure If input water pressure is about 30 to 50 psi, the pump will boost pressure to about 60to 80 psi for RO systems Water open flow 2.6 liter per minute or 0.69 gallons per minute Electrical: 24VAC, 0.70Amp to 1.65amp Connection Inlet and outlet, 3/8" quick connect fitting, also includes two reducer 3/8 to 1/4" fittings Motor Permanent Magnet, 24VAC, enclosed PUMP Diaphragm pump, 3 chamber, self-priming 7 feet prime.
