SCHROEDAHL: Pump Protection
/ Oil & Gas Applications
Oil & Gas Applications
Crude oil pumps, extraction and transport
LNG, LPG, naphta, ammonia pumps (pumps for fluid gas, fluid gas fuel, benzene, fluid ammonia)
Pumps for liquid process material
Booster- or auxiliary-pumps
Seawater-Injection pumps
Fire fighting pumps
Advantages:
More economical to purchase, commission and service, due to less wear
High economical operation due to modulating control of the bypass flow
Strictly mechanical, flow operated, power independent operation
Only one valve without additional components – less susceptible to breakdowns and high wear
Non-return valve and bypass connection are already integrated in the valve
Low maintenance
