• Max. pressure: 110 bar / 1595 psi
• Nominal diameter: 25 – 400 mm / 1-16 in

Mechanical / hydraulic

• Materials: S5, S6, S8, C6, A8, D1, D2 and special materials
• Flanges: Available for all common pipelines, meeting all standards up to PN100 / ASME Class 600.
• Mechanical seals: To ISO 24109 / API 682 in cartridge design.
• Design features:
  • Selection of a balancing system for specific duty points reduces axial forces and extends bearing life.
  • Double volute (DN 80 and above) reduces radial force and prevents shaft deflection, reducing load on bearings and mechanical seal.
  • Maximum permissible shaft diameter to API 610 minimizes shaft deflection and vibrations.
  • A choice of more than 70 hydraulic systems enables optimum pump selection to API for higher efficiencies.
  • Heavy-duty 40° angular contact thrust bearings exceeding API requirements.
  • Oil bath or oil mist lubrication.
  • Steel bearing bracket with integrated cooling fins and optional fan impeller protect the unit from overheating when fluid and ambient temperatures are high, eliminating the need for a cooling water circuit.
