Feature
1、With a pressure switch it will be automatically cut off when the pressure of water outlet is big enough. And runs again when the pressure is going down 2、The mounting feet are rubber instead of rigid plastic, which provides fairly good vibration isolation 3、Built-in pressure switch, it automatically turns on and off as you turn your tap or nozzle on and off 4、Water inlet and outlet interface connect with silicone PE or PU pipe 5、This type of product can be applied to occasions, which have demand for energy conservation and frequent switching, such as machine washing, feeding water to a solar energy system, and remote automatic controlling system of conveying water and suspending water supply, etc.

Description:
This high quality DC micro diaphragm pump with a pressure switch will be automatically cut off when the pressure of water outlet is big enough. And runs again when the pressure is going down. It is not a good idea let this pump runs dry for too long. This type of product can be applied to occasions, which have demand for energy conservation and frequent switching, such as machine washing, feeding water to a solar energy system, and remote automatic controlling system of conveying water and suspending water supply, etc.

Features:

1. With a pressure
switch it will be automatically cut off when the pressure of water outlet
is big enough. And runs again when the pressure is going down.

2. The mounting feet are rubber instead of rigid plastic, which provides fairly good vibration isolation.

3. Built-in pressure switch, it automatically turns on and off as you turn your tap or nozzle on and off.

4. Water inlet and outlet interface connect with silicone PE or PU pipe.

5. This type of product can be applied to occasions, which have demand for energy conservation and frequent switching, such as machine washing, feeding water to a solar energy system, and remote automatic controlling system of conveying water and suspending water supply, etc.

Application: Widely used in general industrial equipment, chemical equipment, agriculture (lawn and garden), vehicle modification, vehicle cleaning, water purification and water treatment equipment and other industries.

Instructions:
1. The direction with a small arrow on the water pump is the water outlet.
2. The wires are not divided into positive and negative poles.
3. The pump can be placed in any direction.

Package Included:

1 x Self Priming Pump

Note:

1. Do not soak in water.
2. The pressure adjustment screw cannot be adjusted at will. The pressure has been adjusted before leaving the factory. The stop pressure can be finely adjusted (the middle screw of the black plastic cover on the top of the pump, clockwise to increase the stop pressure, counterclockwise to reduce the stop pressure)
3. Impurities cannot be pumped in, otherwise the pump will easily be blocked and the pressure will drop to no water.
4. The shorter the inlet pipe, the better, the longest should not exceed 1.5 meters, and the outlet pipe can be as long as possible (within Yangcheng range). Use a tube with an inner diameter of 8mm and an outer diameter of about 12mm
5. Do not pump strong acid and strong alkaline liquids.

Common faults and troubleshooting:
1. When the pump is not operating, check whether the two wires behind the motor are loose.
2. When the diaphragm pump is not used for a long time, the pump head will have no suction. Just drop a few drops of water into the pump port and run for a few minutes, and it can be used normally when the sound changes.
