Gianneschi # MVI-80-230/400V Screw Pump 1.5 KW 2 HP

The Gianneschi MVI-80-230/400V is a 316 Stainless Steel MVI Series Single Screw Pump and Motor unit with Buna Nitrile Stator, Stainless Steel Screw Impeller, 2 Inch BSP Inlet by 2 Inch BSP Outlet Ports, coupled to a 1.5 KW (2 Horsepower), 230/400 volts AC, 50/60 Hz, Three Phase Motor. This is a Positive Displacement volumetric pump capable of delivering continuous and exact amounts of fluids. The fluid is first sucked into the chamber, creating a vacuum and then expelled from the chamber, thus increasing the pressure inside it. A metal single-thread 316 Stainless Steel helical rotor is turned by the motor inside a Buna Nitrile rubber stator with a double-thread helical profile to push the liquid along. The pump can manage all types of fluids such as dirty, viscous and/or with suspended parts. Even though this is a self-priming pump, in order to allow the self-priming and lubricate the stator it is necessary to prime the pump and fill the pump body with liquid before starting the unit. We suggest to install a check valve or no-return valve on the suction pipe in order to prevent the pump empting. The main materials of construction are 316 Stainless Steel (Pump body), 316 Stainless Steel, and Buna-N (stator and seal). The rubber stator, universal joint, and mechanical shaft seal are the main parts that need replacing, and this pump is very easy to repair and service. Motor brushes are available for the motor. At initial startup or after a long time of no use, it is important to verify the correct direction of rotation in order to avoid the unscrewing of the rotor. F class Insulation, IP 54/55 Protection
