Hydraulic actuated diaphragm pumps, also known as hydraulically operated diaphragm pumps, are a type of positive displacement pump that uses hydraulic pressure to drive the reciprocating motion of a diaphragm. These pumps are commonly used in various industries for their ability to handle aggressive, corrosive, and high-viscosity fluids.
The operating principle of hydraulic actuated diaphragm pumps involves the use of a hydraulic system to actuate the diaphragm. The hydraulic system consists of a hydraulic fluid, usually oil, which is pressurized by an external power source such as an air-operated pump or an electric motor-driven pump. The pressurized hydraulic fluid is then directed to a hydraulic chamber, which contains a diaphragm. The hydraulic pressure forces the diaphragm to flex back and forth, creating suction and discharge cycles.
