Design Range

Size Range: From 76.2 mm (3.00") to 254 mm (10.00") stroke, with 12.7 mm (0.50") to 254 mm (10.00") diameter plungers, with power ratings of 45 kW to 2560 kW.

Features & Benefits
  • Sectionalised liquid ends suitable for heavy duty oil & gas applications
  • Monoblock liquid ends more suitable for general industrial services
  • Self-aligning plungers ensure proper concentricity within stuffing boxes
  • Many valve styles to suit all liquid types from clean liquids to hard slurries
  • Stuffing boxes individually fastened to liquid cylinder for ease of maintenance
  • Independent crosshead extension rods for easy access to crankcase oil seals for fast and easy maintenance
  • Totally enclosed power frame is dust and oil tight eliminating atmospheric contamination
  • Cylindrical crossheads and guides maximize the load bearing area and reduce wear, keeping replacement costs to a minimum
  • Various bearing lubrication systems from splash to full pressure

Standard Design
Sectionalised liquid end with multi-cylinder and separate manifolds, clean liquid valves, and splash bearing lubrication

Monoblock Design
Single piece multi-cylinder and manifold combination liquid end with clean liquid valves and splash bearing lubrication

Variable Speed Design
Full pressure or motorised gravity lubrication to cope with lower speeds

High Suction Pressure Design
Special crosshead pin bearings and lubrication system to cope with non-unloading of that bearing

High Liquid Temperature Design
Individual cylinders and special manifold fastening arrangement to cope with thermal expansion effects on plunger centre distance

Slurry Design
Special liquid end arrangement for constant velocity flow, stuffing box flushing, and slurry valves to cope with solids in the liquid

Extreme Pressure Design
Valve-in-Line arrangement to eliminate intersecting bores in the high pressure areas of the liquid end
