Cast Iron Hydraulic Ends 6″ to 10″

Heavy-duty cast iron hydraulic ends for agricultural and industrial applications.

JOVAL Cast Iron Hydraulic Ends (6″ to 10″) are multistage centrifugal hydraulic ends built for high performance and mechanical strength. With flow rates up to 400 m³/h and head up to 398 m, they are designed for deep borehole water extraction, large-area irrigation and demanding industrial processes. Built with GG25 cast iron bodies and impellers and AISI 304 stainless steel internal components, ensuring durability in urban, rural and fire-fighting applications.

Applications

  • Clean water abstraction from deep boreholes, wells, dams and lakes.
  • Urban and rural water supply.
  • Large-scale agricultural irrigation.
  • Fire-fighting systems.
  • Industrial processes and pressurization systems.

  • Never run the pump dry. Not even for a short trial run.
  • A cooling jacket must be installed if the well diameter is considerably larger than the pump.
  • Check rotation direction on three-phase motors.
  • Mandatory installation with metallic piping.
  • Install a non-return valve on the delivery pipe.
  • Mandatory protection: Overload, Short-circuit and Dry running.
