RPHd

Summary

Product identification

The RPHbd is a double-suction, two-stage, heavy-duty BB2 process pump designed to API 610 / ISO 13709 standards.

Operating limits

• Max. flow rate:
  • 50 Hz: 1900 m³/h / 8365 US gpm
  • 60 Hz: 1700 m³/h / 7485 US gpm
• Max. head:
  • 50 Hz: 550 m / 1804 ft
  • 60 Hz: 540 m / 1772 ft
• Max. temperature: -80 °C to +450 °C / -112 °F to 842 °F
• Max. pressure: Up to 100 bar / 1450 psi
• Nominal diameter: 80-250 mm / 3-10 in

Mechanical / hydraulic

• Robust design for longer service life, in heavy-duty design to API 610.
• Optimised pressure boundary and hydraulic system with reinforced optimised shaft.
• Features numerous flange designs and a large choice of materials.
• Materials include S5, S6, S8, C6, A8, D1, D2, and special materials.
• Coolable/heatable seal housing.
• Various bearing lubrication variants, including:
  • Heavy-duty paired 40° angular contact ball bearings.
  • Standard version with oil ring lubrication and labyrinth seals.
  • Version with hydrodynamic bearings for higher energy density.
• Includes balancing line and double volute.
• Integrated cooling fins and optional fan impeller ensure optimum cooling of the bearing brackets, eliminating the need for a separate cooling circuit.
• Ease of service features:
  • Easy to monitor and service due to top-top flange arrangement.
  • Straightforward servicing due to mechanical seals to API 682 (cartridge design).
  • Replaceable casing and impeller wear rings.
  • Modular design system reduces spare parts stock.
• Offers better efficiencies and NPSH values than OH2 pumps, with very low NPSH values due to the double-suction impeller.

Applications

• Refineries
• Petrochemical and chemical industries
• Onshore and offshore processes
