Air Double Diaphragm Pump is a common industrial pump that delivers liquid through pneumatic. The characteristic of this pump is that an elastic diaphragm is set inside the pump body to separate the inlet and outlet, and the diaphragm is periodically vibrated by the action of compressed air to promote the flow of liquid.   Important parts: 1.Pump body: usually made of Plastic, Aluminum alloy, SS304&SS316, TEFLON,PVDF, it has corrosion resistance and pressure resistance, and can withstand the transportation of different media.   2. Diaphragm: Located inside the pump body, it is made of elastic material( Teflon, Santoprene, Hytrel, Viton) and can be completely isolated from the liquid to prevent leakage and contamination.   3. Inlet and outlet valves: Located on both sides of the pump body, the flow direction and speed of the liquid are adjusted by controlling the opening and closing of the valves.   4. Driving device: usually a pneumatic piston, which generates v...

Pneumatic diaphragm pump is a common fluid transportation equipment, widely used in chemical, pharmaceutical, food and other industries.

Electric diaphragm pumps and pneumatic diaphragm pumps are two common industrial pumps. The following are the differences between them in terms of energy drive, operating principle and applications:   1. Energy drive and operating principle: Electric diaphragm pump：It is a diaphragm pump that uses electrical energy to drive the pump. It is mainly composed of a series of components such as motor, reducer, clutch, diaphragm pump, and sensor. The electrically driven reducer is a primary component that reduces the speed of the electric motor to a speed that can drive the diaphragm pump. Electric diaphragm pumps are powered by an electric motor, converting energy into mechanical motion to drive the diaphragm to work. Its working principle is based on the reciprocating piston principle, and is connected to the diaphragm through a motor-driven connecting rod to realize the suction and discharge of liquid.   Pneumatic diaphragm pump：It is a pump that use compresse...

Air pipes and suction pipes are indispensable accessories for pneumatic diaphragm pumps. How are they installed? What should you pay attention to? This article will introduce them to you.   1. Installation of Air pipe The diameter of the suction pipe of the diaphragm air pump should not be smaller than the diameter of the pump inlet. It is necessary to use an unbent suction pipe at the inlet side so that a high vacuum state can occur. The diameter of the outlet pipe should be at least equal to the outlet diameter, or slightly larger to reduce resistance and losses. All pipes and joints must be sealed, otherwise the self-priming capacity of the pump will be reduced.   Pneumatic diaphragm pump device: If the details of the device are ignored, it may lead to unsafe pumping effects and affect the service life of the pump.   Purpose: The orientation of the double diaphragm pump must be convenient for use and facilitate daily inspection and debugging by maintenance p...

The role of air operated diaphragm pump has been greatly appreciated by people in the industry. Because the pneumatic diaphragm pump plays an important role in the transportation of dangerous and corrosive media, how should it be used correctly to increase the service life of the pneumatic diaphragm pump? What are the methods of use?   1. Installation and startup: ​ Place the air membrane pump as close to the product as possible, so that the suction pipeline is short and the number of configured parts is reduced. Do not reduce the pipeline diameter. In order to extend the life of the diaphragm, keep the pump as close as possible to the liquid being pumped. When the inlet pressure exceeds 10 feet (3 meters) of liquid column, a pressure relief adjustment device needs to be installed to extend the life of the diaphragm. If hard piping is installed, use a short length of flexible connection between the pump and the pipe. Flexible connection can reduce vib...
