The support plate can be made by drawing.

The RWP KIT allows quick maintenance and minimal plant shutdowns thanks to the internal cartridge that can be quickly replaced.

Generously sized silicon carbide supports (SSiC) guarantee high wear and temperature resistance.

The elastic compensation provided for them ensures the correct operation even under the toughest conditions (very high and very low temperatures, transients, etc.), compensating for the different thermal expansion of the materials involved. Also available is the tungsten carbide version on Special Carbon, with the ability to ride dry.

As with axial support, the thrust pad is also available in different versions to meet the most diverse needs:

  • Silicon carbide.
  • Tungsten carbide.

The pump bodies are obtained by fusing on the ground, while the impellers are obtained by wax casting in CF8M.

This process enables high-quality components with high precision and reproducibility of the profiles, while maintaining very small overlays, in favor of the simplicity of machining made with CN machines, all to give the highest quality product while keeping prices competitive.

Additional available materials:

  • Hastelloy® C276
  • Incoloy® 825
  • Duplex
  • Other materials on request.

Closed-type impeller, balanced both statically and dynamically.

The axial thrusts are balanced by the counter-pallet rear.

Non-slip parts are painted with epoxy base and acrylic finish, both water-based, for maximum resistance under toughest conditions, with full respect for the environment.

The high-performance, single-piece welded body with the ellipsoidal profile bottom shape is designed to prevent dangerous concentrations of tensions in the material.

Available in two versions: Standard AISI 316 and Hastelloy® C 276, special alloys also employ titanium alloys.

Powerful synchronous magnetic joints, assembled without the use of adhesives or resins, are designed and dimensioned by our Technical Office, adapting to the specific requirements of these pumps.

The particular construction of the internal magnet, made using rare earth magnetic elements, allows the best isolation of the magnet body from the support, while ensuring an elastic mounting of the latter and guaranteeing its best operation even in the presence of significant variations in temperature.

The materials are designed to work at temperatures up to 350° C without cooling.

Transmission power over 500kW.

The static seal is made of flat gaskets, available in different materials, so as to satisfy the most diverse needs:

  • Asbestos free (standard)
  • PTFE
  • Graffiti armed
  • GYLON®
