  • Sturdy design with casted discharge head and motor support
  • Available in AISI 304 (Z6) or AISI 316 (ZN6)
  • Delivery up to: 78 m3/h
  • Head up to: 700 m
  • Max immersion depth: 350 m
The Z6-ZN6 Series: Submersible Borehole pumps for 6" wells.


Z8-ZR8 Series (8" Wells):

Built entirely from stainless steel, the Z8-ZR8 Series is designed for deep wells, mining, municipal, and industrial water supply applications. The ZR8 version features Duplex stainless steel for enhanced corrosion resistance. A dynamic wear ring minimises hydraulic losses, preventing blockages during standby periods.

  • High efficiency design including dynamic wear rings that reduces hydraulic losses
  • Available fully in stainless steel AISI 304 or Duplex
  • Delivery: up to 180 m3/h
  • Head: up to 550 m
  • Max immersion depth: 350 m
The Z8/ZR8 Series: Submersible Borehole pump for 8" wells.


Z10, Z12 Series (10" and 12" Wells):

The Z-ZR10-Z-ZR12 Series is a high-efficiency, multistage vertical centrifugal pump optimized for large-scale applications, including municipal water distribution, firefighting, and agricultural irrigation. The advanced shaft alignment minimizes vibration for long-term reliability.

  • Wear ring design that reduce recirculation
  • Available fully in stainless steel AISI 304 or Duplex
  • Delivery: up to 520 m3/h
  • Head: up to 545 m
The Z Series Submersible Borehole pumps for 10" and 12" wells.


Goulds GIS / GISO Series:

ISO End Suction Centrifugal Pumps – flexible, efficient and highly versatile.

Designed with state-of-the-art Computer-Aided Design (CAD) and Computational Fluid Dynamics (CFD), the Goulds ISO Series pumps meet ISO 2858 standards, offering superior performance across various applications. These pumps are ideal for handling non-combustible, low-viscosity liquids free of solids, abrasives, and fibres.
