Rotary Power Metering Pumps

Rotary Power (RHL Hydraulics) metering pumps represent one of the best values in the industry. They are the product of more than 20 years of development and experience in polyurethane foam processing.

These axial piston pumps are accurate, reliable and efficient, yet cost significantly less than comparable pumps offered by other manufacturers.

Rotary Power metering pumps are designed for high inlet pressures and have been used successfully with all types of polyols and isocyanates (TDI, MDI); polyol blowing agent blends; polyether and polyester resins; and methylene chloride.

Features:

  • Fixed or variable displacement, from 2 to 62 cc/rev.
  • Pressure-balanced controls for ease of operation and accurate metering.
  • Adjust flow with handwheel or variable frequency drive.
  • Low fluid temperature throughout the pump.
  • Twin PTFE seals on a ceramic bush allow inlet pressures up to 20 bar (290 psi).
  • Outlet pressures up to 250 bar (3600 psi ); 210 bar with TDI.
  • No-leakage return line; pump is drained internally.
  • All major components treated to minimize corrosion.
  • Cartridge shaft seals for fast, easy replacement.
  • Leakage indicators between shaft seals and at control.
  • Lubrication ports included.
  • Magnetic drive couplings available.
