EL/Pump MVI60, 230/400 V TR, 50 Hz, 1.1 kW – code: 01GMVI6003 – Gianneschi Pumps and Blowers

Volumetric single-screw self-priming pump MVI60 Gianneschi – 230/400V 3~ 50Hz

The EL/Pump MVI60 by Gianneschi Pumps and Blowers is a volumetric single-screw self-priming pump from the MVI series, designed for technical and nautical applications requiring the handling of fluids that may be viscous or contain small suspended solids.

The version identified by the product code 01GMVI6003 is powered by 230/400V three-phase 50 Hz and develops a nominal power of 1.1 kW. The pump belongs to the system category dedicated to bilge, seawater, diesel, and onboard services, with a typical construction configuration of single-screw self-priming pumps.

Features and construction details

Self-priming single-screw technology

The MVI series uses a metallic helical rotor with a worm screw that rotates inside a floating double-helix rubber stator. This volumetric configuration is designed for handling dirty, viscous fluids with small suspended solids.

According to the manufacturer's technical documentation, the pump is self-priming, but at the first start-up it is necessary to fill the pump body with liquid to lubricate the stator and facilitate priming.

Main materials

The construction uses materials typical of nautical and professional applications:

• Pump body in AISI 316 stainless steel
• 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 configuration is oriented towards compatibility with technical uses and fluids employed in plant and onboard environments.

Operational advantages

Self-priming configuration

The self-priming capability can be useful in systems where suction conditions are not constant or where the pump operates with lines subject to emptying.

Construction in AISI 316 stainless steel

The extensive use of AISI 316 stainless steel on the pump body, rotor, shaft, and cardan joint represents a typical configuration for nautical and professional technical applications.

Handling of viscous fluids and wastewater

The single-screw volumetric technology is designed for applications with dense liquids or containing small suspended solids, maintaining continuous operation in technical systems.

Usage and operational notes

Installation instructions

Before installation, it is advisable to check:

• Electrical compatibility with 230/400V three-phase 50 Hz power supply
• Proper configuration of suction and discharge lines
• Fluid compatibility with pump materials
• Available space for maintenance and accessibility

Manufacturer's recommendations

The technical documentation recommends:

• Filling the pump body at the first start-up
• Installation of a non-return valve on the suction line
• Checking the correct direction of rotation to avoid unscrewing the screw rotor

For installations with top inlet, the manufacturer indicates the availability on request of an elbow joint on the suction side.

Summary

The EL/Pump MVI60 Gianneschi is a 1.1 kW single-screw volumetric self-priming pump powered at 230/400V three-phase 50 Hz. The construction in AISI 316 stainless steel, self-priming configuration, and single-screw technology make it suitable for nautical systems and technical applications dedicated to bilge, wastewater, seawater, and viscous fluids with small suspended solids.
