Internal return shell diaphragm pump

The name of this electric sprayer water pump is the inner return shelled diaphragm small pump, which is characterized by:

1. Good heat dissipation performance of the shell

The pump head is made of high-quality engineering plastics, acid and corrosion resistant,

Not easy to wear, small deformation, more durable.

2. The intelligent single screw water pump is a single core power with strong pressure

Adopt pure copper coil, longer life, ensure the water pump

Stable and efficient operation

3. Internal reflux device with shell diaphragm small pump

内回流有壳隔膜小泵是当水泵压力过高，水在水泵里面

循环减轻水泵压力，从而保护水泵，更加经济实惠。

1. Factory direct sales of internal return shell diaphragm pump

2. The inner-return shell-diaphragm small pump is entirely a pure copper motor produced by its own fully automatic production, which provides more stable power for the pump!

3. A manufacturer that produces tens of millions of pumps a year, this is the reason why there are various types of motors and various pumps for you to choose from

1. The sprayer water pump is divided into internal return water pump/return water pump/intelligent water pump, the difference between the three

Answer: There is a reflux device on the top of the reflux type. After reaching a certain pressure, the pressure can be relieved by means of reflux without suffocating the tube. The internal return does not have this function.

The intelligent pump has a pressure switch on the top. When the handle of the sprayer is closed, the pump will stop working. It has the function of turning off the gun and saving electricity and energy.

2. The sprayer pump does not produce water? Has the water in the pump been used by someone else?

A: Take off the two caps of the sprayer water pump first, and each water pump will be tested before delivery to check whether it is qualified or not, and the water pump will be better preserved.

3. How to wire this sprayer water pump?

A: This electric sprayer water pump is an intelligent single screw water pump connected with the same color line. Power requirements: generally 5a adapter, battery 8ah can be.
