Hercules™ Horizontal Pumping System

Modular skid-mounted surface pump for high-efficiency fluid transfer

The Hercules™ horizontal pumping system (HPS) is an efficient alternative to positive-displacement, split-case, and other surface pumping systems, offering longer run life and lower maintenance costs.

The multi-stage centrifugal pump is mounted on a modular skid, powered by a two-pole motor, and protected by a robust thrust chamber. The system design is based on our proven electric submersible pump (ESP) systems deployed in thousands of downhole applications.

Flexible operating configurations

  • 800 BPD to 70,000 BPD (23 USgpm to 2,000 USgpm)
  • Power units from 20 hp to 3,000 hp (15kW to 2,500kW)
  • Diesel, natural gas engine, steam or gas turbine
  • Discharge pressure up to 7,100 psi (48953 kPa)

Reliable, low maintenance pumps

  • Hoist mounting points for heavy-duty skid to simplify installation
  • Maintenance-free balanced spacer coupling reduces vibration
  • Quick mechanical seal replacement without breaking pump or piping connections
  • Back pullout thrust chamber for quick seal or thrust chamber change out
  • Single mechanical seal assembly, exposed only to intake pressure
  • Mixed-flow stage pump design for reduced abrasive wear, optimal efficiency and head per stage
  • Modular design, adaptable for changing application conditions
  • Minimal noise and vibration and pulse-free flow
  • Health, safety, and environment (HSE) friendly
