Product Description
· Adoption of automatic oil supply and internal safety protection technology based on mutual interaction of diaphragm-limit valve-compensation valve-internal safety valve. The accuracy of a limit valve reaches ±0.002mm, the surface hardness reaches 60~ 70HRC and the roughness reaches 0.4μm; the pump can be reused for 80 million times within a temperature range of -80ºC~160ºC;
· Through multi-directional rolling and surface quenching treatment, evenness of PTFE macro-molecule composite diaphragm reaches 99.92%, cold flow is reduced during operation and compressive strength is enhanced;
· Internal safety valve and compensation valve realizing automatic air discharge and oil replenishment have outstanding and reliable performance;
· Inlet and outlet high-precision check valves can effectively guarantee metering accuracy and fluidity;
· 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;
· When transporting hazardous fluids toxic, flammable, explosive or strongly corrosive, double diaphragms or multiple diaphragms can be used;
· The diaphragm rupture alarm device prevents fluids from contact with hydraulic oil in case of diaphragm rupture, thus avoiding happening of any accident;
· Capacity control modes are diversified, including manual, electrical, pneumatic and frequency conversion adjustment;
· Installation of an electric actuator ensures realization of 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;
· With a wide application range, it can safely transport all kinds of fluids.
