Main Structure of MPD Diaphragm pump
MPD Diaphragm pump applied three different structures of pumps
a.Hydraulic plunger pump
The main function is to transfer the horsepower of the electric motor through plungers to drive diaphragms.
And diaphragms are then used to push the fluid (water or cutting fluid) to achieve a power-saving effect.
The working medium of the plungers is hydraulic oil, it lubricate metal parts keep plungers functional.
The temperature generated by these processes will be sent out of the body by the built-in circulation pump.
The hydraulic oil will be filtered and cooling and then send back to theplunger pump chamber.
This design allows the pump temperature to be controlled at a slightly higher than room temperature.
It is not only protects the pump but also extends its service life.
b. Diaphragm pump
This part is the main structure of the MPD pump, which is using the movement of the diaphragm to push the fluid and transmit it to the circuit of system.
The main mechanism of this part are diaphragms and control valves. During the rapid opening and closing of valves, the liquid is sucked in and push
out of the pump for circulation. The diaphragm structure design has almost no friction during operation, and only very little or no heat is generated. This is the most important for the central coolant system.
The extra radiator system that was originally required can be eliminated or relatively reduced after using the MPD pump.
c. Build-in Circulation pump
Patented build-in circulation pump, which reduce the of oil temperature of the plungers and extends service life of diaphragms.
It is the ultimate choice for high-pressure central coolant system for metal working machines and otherequipments too!
