ClydeUnion Pumps hydraulic submersible pump

When it comes to offshore production, submersible well pumps can be high maintenance and can significantly impact operational costs. The ClydeUnion Pumps hydraulic submersible pump (HSP) was developed by analysing the failure modes of traditional electric submersible pumps and designing them out, creating a pump with ultrahigh reliability and long service life. This pumping solution has typically around three times the life of an electric equivalent and offers increased availability providing for substantial reductions in offshore operational expenditure.

The removal of electrical power systems greatly reduces the opportunity for equipment failure. Longevity is enhanced through the use of the power fluid supplied from the surface, which provides life support to the critical balance and bearing systems. Bearings and seals have also been eliminated, improving reliability and extending the useful working life of the pump.

The HSP operates at high speed and has a high energy density. It is therefore easier to install, and with increased robustness, reduces the risk of damage during its deployment. The single shaft design of the combined pump and turbine enables the HSP to be supplied fully assembled and tested from the manufacturing facility.

The HSP is designed in the highest grade materials to resist wear and corrosion for the full life of a well. Its flexibility of operation means that it can handle 75% continuous gas content and 100% gas slugs, reducing the occurrence and risks of damage from gas lock.
