EVP-GFF serie Pressure Pump are designed for very high inlet pressure, high pumping speed, low power consumption. These series can run up while the inlet pressure is enhanced 1000pa, working while the inlet pressure is enhanced 400pa, continue working 5 min while the inlet pressure at 2000pa , 2 min while the inlet pressure at 3000pa,the max inlet pressure support is 6000pa.
