The characteristics


Pump head can be divided into hydraulic diaphragm, piston, piston (see P15-18) special conditions; 
Safety - motor adopts vertical installation, no leakage;
- hydraulic diaphragm pump USES the built-in relief valve and fill valve, automatic exhaust, fill oil, superior performance and reliable;
- one-piece "ode" worm gear pair of variable-speed drive mechanism, low noise, high efficiency;
The one-piece sleeve - using a patent adjustable eccentric driving mechanism, simple and reliable, stroke can be adjusted 0-100%;
Adopts high precision check valve at the inlet and outlet of the group, effectively ensure the measuring accuracy and liquidity;
- high performance piston and special packing, diaphragm, sealing components, long service life and sealing performance is superior;
- oil-immersed lubrication, ensure the long-term reliable transmission mechanism is used;
- can the same medium and reduce the pulse;Can also transport different medium, can be independent of each pump head flow adjustment, as a proportion of the pump to use;
- the amount range: 10 ~ 100%, the measuring accuracy: + / - 0.5%;
/ flow control mode is diversiform, can be manual, electric, pneumatic, inverter control.

Range of application


 Widely used in petroleum, chemical, natural gas, food, papermaking, atomic energy technology, power plants, plastic, medicine, environmental protection, textiles and mining and other scientific research and production department.Apply to have strong corrosion, volatile, easy to crystallization, inflammable, explosive, toxic, stench, than the big, medium viscosity, radioactive or other precious metals, etc.
