Calder high pressure pump units have been used for water injection and waterflooding operations for many years. Whether for maintaining or increasing well pressure, voidage replacement, or oil displacement, our water injection packages offer a reliable, effective solution. These pump packages deliver fixed or variable flows at a range of pressures to meet the most challenging field conditions. We design and manufacture for both hazardous and non-hazardous, and onshore and offshore locations.

These machines can be diesel engine or electric motor driven and there are a variety of mounting options. The controls can be designed to suit your specific requirements from the basic and simple to full remote control with system health and performance monitoring, and data acquisition and logging capabilities.

At the heart of our units is the ever-reliable Hammelmann reciprocating plunger pump which features a space-saving vertical design, and a high pressure labyrinth seal for long-term reliability.

  • Simple controls to fully integrated, unmanned control systems.
  • Pump flow rate controls allow fixed or variable flow rates using variable frequency or hydraulic drives.

Pump unit control system configurations featuring the following options:

  • Single or multiple pump unit control systems.
  • Operation from a remote location.
  • Local control systems which can be skid mounted.
  • Full integration and interface with client control systems.
  • Use of latest communication protocols.
  • Comprehensive instrumentation with health/status monitoring functions.
  • Full data acquisition and logging capabilities.
