Dongkai is a professional leader China Positive displacement piston pump. A positive displacement piston pump is a particular kind of positive displacement pump in which the piston reciprocates with the high-pressure seal. Liquids can be moved and gases can be compressed using positive displacement piston pumps. They can operate over a wide range of pressures. High pressure operation can be achieved without a strong effect on flow rate. Positive displacement piston pumps can also deal with viscous media and media containing solid particles. This pump type functions through a piston cup, oscillation mechanism where down-strokes cause pressure differentials, filling of pump chambers, where up-stroke forces the pump fluid out for use. Positive displacement piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems.

Dongkai is a leading China Ammonia dispensing pump manufacturers. Ammonia dispensing pump, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. They set the standard for safety, reliability and efficiency, especially when it comes to pumping supercritical fluids.

Dongkai quality Safety Relief Valve for Back Pressure help to relieve excess pressure on the pump system or maintain pressure at a setted point. Safely relief valve is installed on the outlet pipeline of metering pump. When the system pressure becomes abnormal, safety relief valve protects metering pump from any damages. Back pressure valve shall be installed at the outlet of metering pump in order to reduce siphon and excess feeding, and ensure the metering accuracy of metering pump is not affected. When dosing point is lower than the outlet of metering. Each Valve is diaphragm type with 2-port design, which can be used both as safety relief and back pressure valve

China hot selling Stainless Steel Air-Operated Diaphragm Pump Manufacturers and Suppliers.Our range of highly-polished, Stainless steel Air Operated diaphragm pump (304 or 316L) have been specifically developed for applications that demand the highest standards of hygiene and contamination control in a clean and sterile environment.

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.
