EL/Pump MV44 G, 230v M, 50hz, 0.55 kw – code: 01GMV342G – Gianneschi Pumps and Blowers
EL Pump/MV44 G 230V Gianneschi Pump – self-priming single-screw pump for wastewater and viscous fluids
The EL/MV44 G 230V Gianneschi Pumps and Blowers is a self-priming single-screw pump of the MVG series, designed for applications such as emptying black and grey water tanks, handling viscous fluids, and pumping liquids with small suspended solids.
The volumetric helical screw construction allows smooth fluid handling even in the presence of dirty or thick liquids, a feature useful in nautical environments, onboard systems, and technical service applications. The offered version is powered by 230V single-phase 50 Hz with a nominal power of 0.55 kW.
Features and construction details
Self-priming single-screw technology
The MVG series uses a stainless steel helical rotor operating inside a floating NBR double helix stator. This configuration is designed for transferring viscous fluids, wastewater, and liquids with small suspended solids.
Although self-priming, the manufacturer specifies that at the first start-up it is necessary to fill the pump body with liquid to lubricate the stator and allow proper priming.
Main materials
The pump uses materials commonly employed in nautical and plant engineering applications:
- Pump body in bronze
- Screw rotor in AISI 316 stainless steel
- Motor shaft in AISI 316 stainless steel
- Cardan joint in AISI 316 stainless steel
- Stator in BUNAN NBR
- Mechanical seal GRAF-ALLOX-NBR
This construction configuration is oriented towards mechanical robustness and compatibility with continuous technical uses.
