Feature

* No dynamic seal, no leakage and easy maintenance
* The working pressure can be up to 80 MPa; the measurement accuracy can be up to +/- 1%; the capacity range of the simplex pump: 0.2L/H - 12000L/H
* The control of the capacity flow is by adjusting of the length of the stroke and the frequency conversion; meanwhile, the remote automatic control can be available when there is the stroke controller or the frequency changer installed.
* The working temperature of the medium should neither exceed 200ºC nor below -30ºC; otherwise it wil influence the life of the diaphragm
* The new three-valve structure and the application of limit oil compensating mechanism not only ensure the fullness of hydraulic oil in the hydraulic working chamber but also avoid filling oil excessively and prevent hydraulic shock so that make the both sides of the diaphragm have balanced force and increase the working life of the diaphragm to more than 8000H.

Application 

It can be applied in a wide range from the general water of normal temperature to some liquid which are strong corrosive, volatile, vrystalized, combustible, and explosive, extremely toxic, foul-smelling, moderately viscous, radioactive and other valuable liquid. Meanwhile, it can also transfer some suspending liquid. In order to prevent the accidents caused by the mix of the media and hydraulic oil, or in terms of some liquid which are combustible, explosive, toxic and valuable, the double diaphragm hydraulic metering pumps with the alarm functions for the repture of diaphragms can be applied.
