Centrifugal pump MVX series

waterwith asynchronous motorstationary

Product overview
Vertical centrifugal multistage pumps of the MVX series are designed for pumping clean liquids without abrasives or suspended solids. Suitable for non-explosive fluids that are not aggressive to pump materials. Low-noise vertical construction with AISI 304 wetted parts.

Operating limits

• Liquid temperature: up to 35 °C for domestic use (CEI EN 60335-2-41) or up to 120 °C for other uses
• Ambient temperature: not higher than 40 °C
• Maximum working pressure: 25 bar
• Flow rate: up to ≈ 84 m³/h
• Heads: up to ≈ 320 m

Technical features

• Motor bracket: cast iron G20 with anti-corrosive coating
• Pump body: cast iron G20 with anti-corrosive coating
