The Wilo Multivert MVIE 9502/1 (3~380/400/460 V, EPDM, ) is a three phase high-pressure multistage centrifugal pump with a 15kW motor. The Wilo Multivert MVIE range are a range of vertical multistage pumps. They are based on the Wilo Multivert MVI range, but have the added advantage of an integrated variable speed pump inverter. This allows the pump to alter its speed to meet the pressure demand. In most applications this leads to substantial energy savings. A pump with an integrated inverter allows installers to save time on site as the inverter is already wired to the pump on delivery.
