Find a huge selection of Positive Displacement Metering Pump from China at Dongkai. Positive Displacement Metering Pump's operating principle: Reciprocation of plunger drives hydraulic oil, and hydraulic oil drives the diaphragm to reciprocate, so as to suck in and discharge the medium.

Find a huge selection of Hydraulic piston pump from China at Dongkai. A Hydraulic piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. Hydraulic piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without a strong effect on flow rate. Hydraulic piston pumps can also deal with viscous media and media containing solid particles. This kind of pump works by means of a piston cup, oscillation mechanism, and filling of pump chambers through downstrokes that create pressure differentials and upstrokes that force the pump fluid out for use. Hydraulic piston pumps are frequently utilized in water delivery or irrigation systems and in situations where a high, steady pressure is required.

Stainless steel Electric diaphragm pumps combine the advantages of air-operated double diaphragm pumps with an energy efficient electric drive to reduce energy consumption, operating costs and pulsation. The centre section of these pumps use an electric drive instead of compressed air. The centre section is filled with pressurised air and is mechanically moved by the motor pushing and pulling the diaphragm from left to right. This back-and-forth motion, forces material out of one chamber and into the outlet manifold, whilst filling the opposite fluid chamber via the inlet manifold. The smooth changeover allows for reduced pulsation at the outlet.
