  • Summary
  • Applications

    Systems requiring low to medium flow - high head such as domestic water pressure boosting, fire safety (‘jockey’ pumps), boiler feed water, cooling tower make-up water

  • Description

    Armstrong 4700 Vertical Multistage (QVMS) Pumps are high-efficiency, space-saving solutions engineered for applications requiring high pressure, reliability, and energy optimization. Featuring precision-engineered stainless steel hydraulics, advanced mechanical seals, and inverter-ready motors, these pumps deliver exceptional performance across a wide range of flow and head conditions. They offer quiet operation, low maintenance, and long service life, best suited for installations where performance, durability, and compact footprint are essential.
