R Hot water circulation centrifugal pump end suction cantilever

Robust end-suction, cantilever centrifugal pump engineered for circulating hot water and other clean liquids without solids. Designed for industrial hot-water circulation duties in metallurgy, power, plastics, rubber, textile, chemical, wood and paper processes and central heating systems.

Key features

• Construction: single-stage single-suction or two-stage single-suction cantilever centrifugal design with horizontally axial inlet and vertically upward outlet.
• Temperature and pressure capability (dependent on flow-component material):
  • Ductile iron: service temperature ≤ 150 °C, working pressure ≤ 2 MPa
  • Cast steel: service temperature ≤ 207 °C, working pressure ≤ 4 MPa
  • Cast stainless steel: corrosion-resistant, service temperature ≤ 250 °C, working pressure ≤ 5 MPa
• Mechanical aspects: impeller statically balanced and secured to shaft with nut and sleeve; pump shaft supported by a suspension frame using one pair of radial thrust ball bearings plus one single-row radial ball bearing (or single-row radial cylindrical roller bearing).
• Sealing options: floating sealing ring or high-temperature/high-pressure mechanical seal. Axial thrust is carried by a single-row radial thrust ball bearing; some impellers include back vanes to help balance axial thrust.
• Cooling: floating ring seals and suspension-frame components include cooling chambers; recommended external cooling water flow 0.3–0.6 m3/h.
• Drive and rotation: direct motor drive via elastic coupling; pump rotates clockwise as viewed from the transmission end.

What this pump delivers for B2B purchasers

• High-temperature capability up to 250 °C when specified in corrosion-resistant materials.
• Multiple material options to match temperature, pressure and corrosion requirements.
• Serviceable design with accessible bearings, seals and replaceable components for lower lifecycle cost.
• Configurable sealing and bearing arrangements to suit site cooling and reliability requirements.

Ordering and selection notes

• Specify required material for wet-end components (ductile iron, cast steel or cast stainless steel) to meet your temperature/pressure and corrosion needs.
• Indicate seal preference (floating ring or mechanical seal) and whether back-vaned impellers are required for axial thrust balance.
• Provide operating temperature, pressure, fluid properties and duty point (flow/head) so the appropriate model and stage arrangement can be selected.

Typical industries and uses

• Hot-water circulation loops and industrial heating systems
• Process circulation in metallurgy, power plants, chemical and textile industries
• Circulation for rubber, plastics, wood and paper processing lines

This pump is a purpose-built solution for industrial hot-water circulation where durability, high-temperature operation and configurable materials/sealing are required.
