Produced water injection pumps
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 are designed to suit your specific requirements. Packages start with basic controls for integration into existing systems. However, our projetcs frequently include full remote control with system health and performance monitoring, and data acquisition and logging capabilities. Through our in-house electrical & instrumentation team, we are able to provide a control system to suit your very specific requirements.
The Pump
At the heart of our produced water injection pumps and packages 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.
The design of a produced water pump unit for an unmanned platform is detailed in this case study.
