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.

How Reverse Osmosis Booster Pumps Work
The purpose of the reverse osmosis booster pump is to increase water pressure going into the RO unit.

Reverse osmosis is a pressure-driven process. Small residential RO units will theoretically operate on very low pressure--down to 35 psi, according to some membrane makers--but the reality is, you won't get a lot of water and the product water quality will be compromised if the unit runs below 45 psi. Low inlet pressure makes the unit produce more reject water, produce less drinking water, fill the storage tank more slowly, and produce lower quality water.

RO units run well on typical city water pressure of 60 psi, but they run even better with a small pump to boost the pressure to 80 psi or higher.

The picture above shows the three essential elements of the ro booster pump. The white object at left is the transformer. It plugs into a standard wall outlet and converts to the voltage (most commonly 24 volts) required by the pump. The large object is the pump itself. The third device is the pressure switch. It monitors the water pressure in the RO unit's storage tank and turns the pump off and on in response to storage tank pressure. The most common shutoff pressure for undersink home RO units is 40 psi.

Do You Need a Booster Pump?
Most city water reverse osmosis users have enough city water pressure to run their RO unit nicely and they do not need a booster pump. For example, if your city water pressure is 60 psi or more, there is little to be gained by adding a booster pump. If your pressure is 50 psi or less, however, a pressure boost pump will give your RO unit more zip. You'll have more water, at a higher pressure, in the storage tank, and the tank will fill faster. The increased pressure will also improve the economy of the unit (it will run less reject water to drain) as well as the quality of the water. RO units thrive on pressure.
