LDP Long Distance Pump

LDP Pump

Extended Range, Deep Vacuum Conveying Power

High efficiency, claw style Long Distance 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

Deep vacuum can provide conveying performance to 1000 feet {304 meters}.

Increase conveying system performance

Replace your pump with a LDP to solve conveying problems without redesigning your conveying or vacuum tubing network.

Broader adjustment of air-to-material ratios

Increased vacuum conveying power at the material pick-up point provides trouble-free resin flow without line plugging or surging.


LDP Pumps must be used in conjunction with a Conveying System Dust Collector installed on the vacuum line prior to the LDP inlet. LDP pumps are equipped with:

  • Voltage matched, magnetic pump starter with 24 VDC starter coil
  • Mechanical vacuum relief valve
  • Vacuum idle mode valve with filter (requires 90 to 120 psi {6.2 to 8.2 bar} compressed air)
  • 12 square foot pump protection cartridge filter in no-tools access housing
  • Vacuum gauge
  • Internal cooling fan


  • 3-phase disconnect switch (Use of a 3-phase disconnect switch near the pump installation is recommended.)
  • Aftercooler on dust collector
  • Pump stacking stand
