LDP Long Distance Pump

LDP Long Distance Pump
Central Vacuum Pumps

High efficiency, claw style positive displacement pumps provide the highest level of vacuum power available for conveying plastic material.  The LDP employs an advanced claw-shaped lobe design that cuts through and pressurizes air in a quiet, nearly maintenance free package.  The direct drive pump delivers stronger conveying performance at longer distances and higher elevations for challenging resin transfer applications.

  • Extend conveying system range
  • Increase conveying system performance
  • Simple alternative to pressure systems
  • Broader adjustment of air-to-material ratios
  • Ready to install
