Dispensing Water Pump Open Flow 3 L/M Built-in Pressure Switch 0.45MPa (65psi) off

E-CHEN Delivery/Transfer water pump RV Series

E-CHEN delivery pumps (also known as demand pumps, dispensing pumps and transfer pumps) are designed for intermittent duty, though most models can be run continuously for hours at a time. Delivery pumps are most commonly used either to pressurize water from an atmospheric tank, to deliver purified water to a specific point of use, or simply to increase water pressure when required.

These diaphragm pumps are controlled by a pressure switch. When required, an integrated bypass can be incorporated to help regulate pressure levels. Customized voltage to 110-240 VAC or 12V or 36V also available upon request.

Working Theory
1. Diaphragm pump rely on, diaphragm leaf back and forth, then change volume to suction and output liquid. So it called Diaphragm Pump.
2. Motor consist of rotor, pump body, finished front cover and finished rear end cover.
3. Pump Head are assembled with driving head, pump cover, diaphragm leaf, piston, finished valve carrier, bypass spring and top bead.
4. Pump head and motor make a whole pump. Rotor in Motor driven back and forth, and drive eccentric gear moving.
5. Eccentric gear drives diaphragm leaf, and compress air to get energy. Energy transfer to pressure, and get effect of booster water pressure.
6. Pumps divide into Booster series and Self suction series. Working time should be less than 6 hours per day.

Installation Instructions
1. In case of water leakage, pump head should be downwards or flat wise when install.
2. A filter, not less than 100um, should be install before pump, incase particle dust go into pump and effect its function.
3. Pump already have passed many functional testing, please don’t open it by yourselves.
4. This pump cannot be used for oil, chemical liquid or corrosive gas condition.
5. If don’t comply with above rules and lead to products damage, we will not offer free warranty. Users should not tear up the seal.
6. Warranty is 12 months from delivery month.



Direction for Use
1. Price quote don't include freight, extra tax, connector, wire connector, power adapter. 6PCS per small carton, 12 PCS per big carton. Warranty one year.
2. Self suction pump is also booster pump, can work with zero PSI source water, suction height 2 meters.
3. For connect type, 50GPD and 75GPD have option of 1/4” quick and 3/8” screw, and 100GPD to 800GPD have option of 3/8” quick and 3/8” screw.
4. 1/4” quick fitting pump should use pullover. Pullover should be put inside first, then put elbow connector. Or elbow connector hard to pull out.
5. 3/8” screw pump should connect with 3/8”screw-1/4”quick or 3/8”screw to 3/8”quick elbow connectors.
6. All pumps should work under DC24V, should connect with power adapter. Please don’t connect with 220V AC directly.
7. Rated current of adapter should not less than pump’s max current. Or adapter will be burn out.
