Stainless steel rotor for Gianneschi MVI20

Maintain the hydraulic performance of your Gianneschi MVI 20 pump.

The impeller (or rotor) is the central component that generates pressure within your pump. For the MVI 20 series, Gianneschi designed this stainless steel impeller to offer significantly greater durability than standard models. It is the essential replacement part to restore your equipment's original performance after extended use.

Key features of this original impeller:

• Stainless Steel Construction: Provides complete protection against rust and premature erosion, even in the presence of sediment or when used with seawater.
• Perfect Fit: As an original manufacturer's part, it installs without any modifications to the shaft of your MVI 20 pump.
• Performance and Quiet Operation: The dynamic balancing of the impeller reduces vibrations, protecting the mechanical seal and minimizing operating noise in bilges or technical rooms.
• Energy efficiency: The smooth stainless steel finish optimizes water flow, allowing the motor to work less hard for the same flow rate.

When should you replace it?

An impeller should be replaced if you notice a drop in water pressure, if the pump takes longer to prime, or during a general overhaul following accidental blockage of the pump by a foreign object.

Lyvio Team Tip: For professional repairs, we suggest checking the condition of the mechanical seal when disassembling the impeller.
