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.

Low Price Chemical Dosing Systems made in China. A chemical dosing system is a facility for automated injection of reagents into a wastewater network for the control of septicity and odour emissions. These systems are typically used at pump stations, sewer manholes, and rising mains. However, they can be installed any place where odour containment is required.

Dongkai is a leading China Bladder-Operated Vibration Absorber manufacturers, suppliers and exporter. The Bladder-Operated Vibration Absorber could be considered as the most traditional and widespread dampener, since it offers a great performance and is manufactured in a very wide range of sizes and building materials. Competitive in price, it is also easy to install. It is specially indicated for clean liquids without suspended solids and of low viscosity. It is manually adjustable and usually installed together with back pressure valves to guarantee the correct pressurisation of the air chamber in relation to the working pressure of the pump, being this assembly very common in diaphragm or piston metering pumps.
