Crude oil pipeline mountainous terrain

In remote areas, there may not be power available, or, terrain may be so steep that all the pressure rise has to be made in 1 station. Each pump must make the entire head. Pumps are often run in parallel. Hundreds of Sulzer multistage pump performances meet such high pressure requirements.

Crude oil pipeline offshore to onshore

All the pressure rise must be made in the crude shipping pumps on the platform. Salt spray is corrosive and platform movement during storms can affect reliability. Specially packaged Sulzer multistage pumps are used to move crude oil from offshore platforms to onshore storage or pipeline systems.

Water injection pump

Sulzer offers both topside (Platform or FPSO based) and Sulzer / FMC subsea water injection pumps to boost output from maturing subsea oil fields.
