MXVF – Permanent Magnet – Variable Frequency – Vertical multistage centrifugal pumps

Vertical, in-line multistage pump with a permanent-magnet variable-frequency drive built into the motor. It holds a constant set-point pressure while matching speed to demand — ideal for energy-efficient water-supply and pressure-boosting systems. IE5-class efficiency, on-board touch-screen control, flows up to 70 m³/h and heads up to 346 m.

The METTA MXVF series brings electronic speed control directly onto the pump. A permanent-magnet motor with an integrated variable-frequency drive continuously adjusts the pump speed to follow real demand, maintaining a stable set-point pressure without an external control cabinet. The drive is operated from a smart touch screen on the motor that displays operating data — pressure, frequency and status — and provides a built-in fault/breakdown guide for fast set-up and service.

Designed water-supply and pressure-boosting systems, the MXVF replaces the start-stop cycling of fixed-speed pumps with smooth, modulated operation. This cuts energy consumption, lowers noise, and reduces the pressure surges and mechanical stress that shorten the life of conventional sets. The permanent-magnet motor reaches efficiency above an equivalent asynchronous motor, in line with the IE5 efficiency class, so the energy saved over the operating life is substantial.

The range spans thirteen flow families from 1 to 45 m³/h nominal (flows up to 70 m³/h), each offered in multiple stage builds for heads up to 346 m and powers from 0.75 to 45 kW. Hydraulic parts are available in AISI 304, AISI316 stainless steel or duplex 2205 to suit the water quality, with flanged connections. The vertical in-line layout keeps suction and discharge on the same centre-line for a compact footprint and simple pipework.

By matching pump speed to actual demand, the MXVF series reduces energy consumption and avoids the pressure surges and mechanical stress associated with fixed-speed pumps that start and stop frequently. The motor reaches efficiency levels above an equivalent asynchronous motor, in line with the IE5 efficiency class.
