MVI Vertical Booster Pumps

Wilo MVI Booster Pumps


Technical Characteristics:
  • Stainless steel in-line pump
  • Standard three-phase motor of V18/V1 construction
  • Temperature of pumped medium ranges from 15°C to +120°С
  • Max. process pressure is 16 and 25 bar;
  • Steel quality: 1.4301 or 1.4404
  • Oval counter-flanges (from Rp 1 to Rp 1 1/2) are also supplied for PN16 construction


Wilo Multivert MVI refers to a vertical centrifugal booster pump characterized by moderate suction and in-line construction. Impeller and the driving wheel, as well as the rest of the pump parts are made of chromium-nickel steel. The pump construction contains a sliding mechanical seal that is not dependent on rotation direction. The motor and pump shafts are connected by a fore spherical coupling. The antifriction bearing installed on the lantern, fully compensates the axial hydraulic power.

The pumps are equipped with a standard three-phase or single-phase motor (max. 1.5 kW) of V1 or V18 construction.Three-phase motors should be protected, while single-phase motors are equipped with built-in protection and a capacitor. All plastic parts are approved by KTW / WRC. PN 16 construction  features oval flange, and GG-mating flange. PN 25 construction  circular flange.
