The pumps 200-HQV are used for pumping both clean and turbid water without big solids in severe conditions. They are suitable for irrigation, water pumping off on water construction works, from water reservoirs, pumping off during floods, in various water pumping stations and works, etc. Maximum temperature of pumped liquid is up to 60 °C. As these pumps are intended for relatively big capacities it is necessary not to exceed NPSH during their operation. An Exceeding of NPSH causes lower capacity of the pump or its breakdown due to cavitation effect. We recommend to use hand wing pump for flooding the pump and suction line or vacuum pump driven with electric motor in the case of longer or bigger diameter suction line.
