Reciprocating Pump
3-GUPD

The 3-GUPD pump assembly utilizes a rugged split crank case drive design that is force fed pressurized lube oil for maximum reliability and longevity. The drive end is made from heavy duty cast ductile iron and is equipped with an external digital tachometer port, robust ductile iron connecting rods, alloy steel crankshaft, and crosshead pistons that are hard anodized for wear and corrosion resistance. The drive is coupled to a selection of 3 sizes of heavy duty high pressure cold ends that are designed for maximum strength and durability while optimizing mass distribution to achieve rapid cool down.

Features & Benefits

  • Rugged, heavy duty construction allows for high reliability in oil well service operations
  • Main shaft is pressure lubricated minimizing wear and tear on bearings/ crosshead piston while keeping all components cool
  • Interchangeable with SG cold ends expanding capabilities. All cold ends have minimal material for quick cooldown and minimal wear and tear at start-up
  • Multiple cold end sizes and drive end strokes allow for wide range of flows and pressures providing flexibility to end users and applications

Applications

  • Oil Well
  • High Pressure Systems
  • Mobile Pumping
  • N2 Purging

Liquids Pumped

  • Ethylene
  • Methane (LNG)
  • Nitrogen
