DPV Heavy Duty brochure

Summary

Product identification

• Heavy Duty DPV multi-stage centrifugal pumps
• Designed for demanding operating conditions and extreme industrial applications, including boiler feed and RO.
• Model Range: VCF 10/15 B (with 2/4/6 to follow later).

Operating limits

• Pressure class: PN16/25 (optionally PN40)
• Medium temperature: -20°C - 140°C

Mechanical / hydraulic

• Key Features for Demanding Conditions:
  • Low NPSH-r version: Equipped with a Low NPSH impeller in the first stage for greatly improved NPSH properties to mitigate cavitation.
  • Tough TUC/TUC bearings: Standard in a reinforced construction to withstand vibrations, axial forces, and reduced lubrication.
  • Cartridge mechanical seal: Standard, available in various material versions depending on the medium.
• Design addresses major causes of pump failure:
  • Air in the medium (e.g., due to cavitation)
  • Imbalance and vibrations (e.g., 'running off the graph', cavitation)
  • Short dry running
  • Thermo shock
  • Extreme axial forces (e.g., upthrust, sudden operation outside the graph)
• Additional Options:
  • Electrolytically polished and passivated hydraulic package
  • Acceptance and test certificates (including 2.1; 2.2; 3.1 and LR, BV, ABS, DNV GL 3.2)
  • Seals with various certifications

Electrical

• ATEX EEXe II T3/EEXd IIC T4 versions available.
• Various voltage versions available.
