Work Principle

The plunger directly contacts with fluids, and the volume of the working chamber changes cyclically with reciprocation of the plunger, thus realizing fluid suction and discharge.

Features

● High performance plunger, special imported packing and sealing components with a long service life and excellent sealing performance;

● Inlet and outlet high-precision check valves can effectively guarantee metering accuracy and fluidity;

● A simple structure, convenient maintenance and high cost effectiveness;

● Integrated worm gear, used as a variable speed transmission mechanism, features low noise and high efficiency;

● Adoption of a patented integrated sleeve adjustable eccentric transmission mechanism, simple and reliable, and stroke can be steplessly adjusted in the range of 0%-100%, the metering accuracy is ±0.5% (10%-100% adjustment range);

● Oil-immersion lubrication ensures reliable use of the transmission mechanism for a long term;

● Capacity control modes are diversified, including manual, electrical, pneumatic and frequency conversion adjustment;

● An electric actuator is supplied to realize automatic remote control;

● Two pump heads or multiple heads (12 at most) can be connected in parallel; a pump with two or more heads can be used to transport a same fluid to reduce pulses or transport different fluids as a proportioning pump;

● Due to absence of a safety relief device, it is suggested to install a safety valve on the outlet pipeline of a pump.
