First, pneumatic, no spark, especially applicable to explosion-proof;
Second, medium flow can through the compressed air inlet valve to make infinitely adjustment;
Third, self-lubricating, low gas consumption, mobile install and use;
Fourth, medium outlet pulse-free, no impact exercise, feed fluid uniformity;
Fifth, the diaphragm uses corrosion resistant material, can transmit various corrosive medium.
This pump has left and right two groups of diaphragms, aim to separate the left and right surgetank with the medium convey cavity. When the valve core of the reversing valve in the right place, compressed air into the left surgetank, meanwhile, the compressen air of the right surgetank will be outlet. Along with the increasing of left surgetank pressure, left diaphragm will extrusion towards left, to make increasing the pressure of the transmission cavity, the medium of the inner cavity through the single valve and convey upwards, then outlet by the exit, right transmission cavity single valve turn off.
Then the back valve corn of the renersing valve move to left, start the next transmit process, move in circles, therefore reach the working purpose of transmitting medium.
First, diaphragm is a fragile article, when the pump continues working eight months, we advice changing it in time, lest the diaphragm broken, then caused the transmit medium into air cavity and damage the pump body.
Second, this pump reversing valves has auxiliary start-up devices (start seal), when the pump initial start hard or stopping work, you should first turn off the inlet regulator, then use finger pressing start up pin, open the inlet valve can recover normal working condition.
Third, when the pump working properly, you still need to check the filter of the end of the medium pipage wheather blockage, if necessary you should clean it.
Under the pump body, there are four fixed feet holes, whose diameter is 8mm, aperture is 135 *, 95mm, these are used to fix the pump body in the right place.
