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. Can be widely used for garden sprinklers, shower, agricultural spray, water taps in the boat, caravan or motor home.

Warm Tips:

1. According to the water pump parameters,please select the corresponding voltage, current, flow diameter blowholes and similar tools.
2. The water pump is strictly prohibited to place into the water, the motor can not touch water; Please Installed it in a dry, ventilated location;
3. The pressure adjustment screw can be adjusted freely.If the pump pressure is high, it is easy to suppress the burst pipe before delivery pressure is adjusted.Tighten the screw down, it will be high pressure;loosen the screw will lower the pressure.High pressure and high current will affect the lifespan of the water pump.
4. Do not use hot water more than 60℃(140℉) high temperature or dirty water (Mud and sands in dirty water will make the pump clogged and ruin the pump). The motor still won't stop running even the water outlet is blocked but the reflux valve will be opened and water circulates in the pump in that situation.
5. Prohibited to use this pump without using a filter. The mesh density is better to be more than 80 mesh.
6. The diameter of the blowhole must conform to the specified value, otherwise the motor pump might be damaged .
7. It is recommended that the complete power cord should be 0.75mm² (copper wire) and 2.5m long. It should not be too long or too thin.
8. If the pump does not absorb water, please select the corresponding current (3A-12A) for the power supply. Make the inlet to draw the water or the outlet to suck the water.Check whether the inlet water is in the opposite direction, or there is any impurities in the pump. Make sure the suction Vertical distance is in Within 1-2 meters, the upper and lower diaphragms are mounted, etc.
9. This pump is a Intermittent type pump, it can not be used continuously for a long time. The specific time depends on the use of the application.

Instructions:

1. The arrow mark of the pump represents the water outlet and the other side is the water inlet.

2. connect the pump to the inlet and outlet pipes, you must ensure a compact connection between the inlet /outlet pipes and the pump. Failure to do so may result in low pressure or leakage.

3. For the Inlet filter,it is required to have greater than 80 mesh filter density (EG 1 square centimeter 80 holes).

4. Turn on the power, and the pump start running.5-10 seconds of water effluent, the air in the pump and piping will be emptied. After the water effluent is stable, temporarily turn off the power and connect the water gun (or similar tools).
