As the name implies, a diaphragm type metering pump with special design and processing of flexible diaphragm displaces the piston, under the action of the driving mechanism to reciprocate, suck - discharge process. As the diaphragm isolation function in structure, truly realize the measurement of fluid lubrication mechanism and drive between the isolation. High tech structure design and adoption of new materials have greatly improved the service life of the diaphragm, and composite materials excellent corrosion resistance, diaphragm type metering pump has become fluid in the application and measurement of main pump. The diaphragm type metering pump family member, liquid force driven diaphragm pump adopts the hydraulic oil evenly driven diaphragm, to overcome the mechanical direct drive pump diaphragm stress over-concentration of the shortcomings, to enhance the diaphragm life and maximum working pressure. In order to overcome the single diaphragm meter pump may arise due to damage caused by the failure of the diaphragm, the diaphragm metering pump with diaphragm rupture damage sensor, realizes the automatic interlock protection with double diaphragm pump head; structure measure to further improve its safety, suitable for the safety protection of particularly sensitive applications.
As a kind of diaphragm metering pump, electromagnetic drive type metering pump with an electromagnet produces a pulsating driving force, obviates the motor and the transmission mechanism, which makes the system compact, small range and low pressure metering pump branch.
Now, precise metering pump technology is already very mature, the fluid metering delivery capacity maximum, working pressure up to 500bar, work covering all areas of industrial production requirements.
