Plunger Metering Pump
The plunger is in direct contact with the medium, and the volume of the working chamber is periodically changed by the reciprocating motion of the plunger, thereby achieving the suction and discharge of the medium.


◆High-performance plunger and special packing and sealing components, long service life and superior sealing performance;

◆Advance and export adopt high-precision check valve group to ensure metering accuracy and circulation;

◆Simple structure, convenient maintenance and high cost performance.

◆Integrated "Oude" worm gear auxiliary transmission mechanism, low noise and high efficiency;

◆Using a patented integral sleeve adjustable eccentric transmission mechanism, it is simple and reliable, the stroke can be 0-100% stepless adjustment; the measurement accuracy is ±0.5%.

◆ Oil-immersed lubrication to ensure long-term reliable use of the transmission mechanism;

◆ Various flow adjustment methods, manual, electric, pneumatic, frequency conversion;

◆With electric stroke adjustment mechanism, it can realize remote automatic control;

◆It can be double or multi-headed in parallel, up to 12 heads; multiple pumps can be used to deliver the same medium to reduce the pulse; or a variety of media can be transported for use as a proportional pump.

◆Without safety relief device, it is recommended to install a safety valve on the outlet line of the pump.

Material selection

The pump head can be 304, 316, 316L, 904, Hastelloy C, polymer, etc.

Application range

Widely used in petrochemical, natural gas, oil and gas fields, plastic foam, electricity, metallurgical cleaning and other fields. Especially in the process of conveying various liquid media such as high viscosity, high pressure and high temperature, it is particularly popular.

◆ Single pump head flow range: ≤12100L/h;

◆Up to: 228MPa
