PERFORMANCE DIAGRAM

BOXER 251 Diaphragm Transfer Pump

This figure shows the dependence of the head and pump capacity on the pressure and air flow of the compressor. The higher the compressed air pressure, the greater the head and the higher the performance curve, in turn, the speed of pumping liquid is regulated by changing the air flow rate.

For example, at a pressure of 7 bar, the optimal operating mode will be pumping 200 l / min with a head of 35 meters, the air consumption will be 2400 nL / min.
