Operating Principle

DP series diaphragm pump is a special form of positive displacement pump. The circular motion of the motor is used to make the diaphragm inside the water pump reciprocate through a mechanical device, thereby compressing and stretching the air in the pump cavity. Under the action of the one-way valve, a positive pressure is formed at the drain port; a vacuum is formed at the pumping port , Resulting in a pressure difference with the outside air pressure. Under the action of the pressure difference, the water is pressed into the water inlet and then discharged from the drain. Under the action of the kinetic energy transmitted by the machine, the water is continuously sucked and discharged to form a relatively stable flow.

Characteristics

Easy to install
DP series diaphragm pump has the advantages of small size, beautiful appearance, compact structure, low noise and high pressure. It is an ideal equipment for civil and commercial use.

Excellent performance
DP series diaphragm pumps can choose different materials (GFRPP/GFRPA), which can safely transport various liquids. Built-in pressure switch, no oil seal, excellent sealing performance, fast and stable self-priming, absolutely no need to add water by hand.

Life extension
DP series diaphragm pumps allow dry operation. The pump cavity is separated from the motor, and the liquid will not penetrate into the motor and cause failure when used for a long time, thus greatly extending the service life of the pump.

Complete specifications
There are more than 20 types of DP series diaphragm pumps. In addition to the standard, there are oil-resistant and corrosion-resistant types. The product models are rich and diverse, with maximum flexibility in selection.

Applications

DP series diaphragm pumps are suitable for liquid transportation such as reverse osmosis water purification systems, spray devices, industrial equipment, automobile washing, sanitation facilities, and medical equipment.
