Process technology for subsea applications
Highly innovative onshore technologies are increasingly being used underwater. Hammelmann process pumps carry on this pioneering trend and have already proven themselves many times when used underwater. The reliable functionality is based on specially selected, certified materials. The pumps are powered by an electric motor. Thanks to their hermetically sealed intermediate chamber, Hammelmann process pumps offer a clean technology.
Built for high-pressure injection at 10,000 ft.
Pressure encapsulated
Oil filled, fully pressure compensated
Variable displacement pump
Heavy duty API 675 design
Safe start against full well pressure
Long life material and design selection
Subsea Injection Pump – HAMPRO® 70 V
The pump and drive components are fully encased and compensated to suction pressure, for their environmental protection, and they share a common lubricating oil system. Hammelmann’s patented sealing system ensures limited and predictable maintenance and unmatched operational reliability. Most all fluids can be pumped by the
HAMPRO® 70 V up to exceedingly thick 2000 centipoise viscosity. Materials were specifically selected for long life submerged service which makes this pump ideal for recovery for future re-use.

Technical details
Variable displacement
The Hammelmann HAMPRO® 70 V Subsea is configured with a variable displacement feature
- Remotely change its flow rate from zero to full flow via servo-motor
- Complete and remote control over fluid flow
- Real time adjustment of the pump while enabling zero or low flow start-up to support extremely high inlet pressure, and limit start-up current in-rush
- Fixed displacement design available when variable
- displacement is not required
Versatile pressure and flow
Hammelmann pump pressure capacity and flow rate are determined by the plunger diameter, sleeve, and head selected. There are many versions available listed in the pressure and flow table to select from. The larger plunger diameter will deliver larger flow rates and typically lower pressures, however, with the Hammelmann variable (V) style pumps the flow rate can be adjusted from maximum flow to zero flow independent of the plunger diameter.
Specific subsea use
- Protects the pump from pressure differences and external impact
- Allows sharing of lubricating oil throughout the housing and components, eliminating additional sealing, minimizing potential failure points and guaranteeing corrosion protection
- Components are isolated from saltwater allowing use of standard subsea designs that meet TRL Level 7
