Submersible Borehole Pumps for 10″ & 12″ Wells GZ 10-12

Overview Specifications Solutions Documentation & Tools


Product Features
  • High efficiciency design in wide performance area
  • Wear ring design that reduce recirculation
  • Avaialble fully in stainless steel AISI 304 or Duplex
  • Delivery: up to 520 m³/h
  • Head: up to 545 m

The GZ10 - GZ12 Series is a multistage vertical centrifugal pump designed for use in 10” and 12” wells. The range is designed to give high efficiency throughout its performance area and almost every duty point between 120 m3/h  and 460 m³/h has an efficiency higher than 80%. The shaft alignment of the pump is specifically designed to reduce vibration issues throughout the lifetime of the pump.  The wear ring on the GZ10/GZR10 pump also keeps recirculation losses to a minimum, ensuring high levels of efficiency in applications such as supply of surge tanks and reservoirs, fire fighting and agricultural flood irrigation.

GZ10-GZ12: AISI 304

All GZ10 - GZ12 pumps can be coupled to NEMA standard motors.
