Reciprocating Pump
P1100

The P1100 model is an oil lubricated cylinder filling pump that has a vertically positioned floating plunger designed for extended life. Its large piston diameter and long pump stroke allow for substantially decreased operating speeds and significantly improved smooth operation. The newly designed adjustment free packing is state of the art, promoting seal longevity and long term leak free operation.

Features & Benefits

  • Vertically positioned floating piston means longer life
  • Simple cold end design assembly, easy maintenance
  • Large piston diameter and longer pump stroke mean slower speeds and smooth operation
  • Pump packing is easily adjusted through a large access port, which allows for extended packing life
  • Splash oil lubricated drive provides extended pump life and minimizes maintenance requirements

Applications

  •  Carbon dioxide cylinder filling
  •  Nitrous oxide cylinder filling

Liquids Pumped

  • Carbon Dioxide
  • Nitrous Oxide
