Reliable, high efficiency performance with highly engineered API pumps for critical upstream and downstream services.
Highly reliable with a long life, Marelli multi-stage pumps are capable of reaching massive flow rates and pressures. They are ruggedly designed to run continuously for years with rugged rotor designs and low vibration balanced rotor designs. They are efficiently designed to save energy and meet exacting API 610 and ISO 13709 standard requirements for overhung, between-bearings and vertically-suspended centrifugal pumps.
Process engineers utilize Marelli heavy duty pumps for refining, petrochemical, offshore, floating production storage and offloading (FPSO) operations, floating liquified natural gas (FLNG) facilities, chemical and general industries requiring high-pressure and flow. These pumps were originally manufactured under the Marelli Bombas brand in Spain. The install base of Marelli pumps is over 10,000 units, many running for decades.
Large engineered water pumps for refining cooling towers, raw water intake, water transfer, irrigation and large osmosis plants are also designed and manufactured in the Illescas, Spain facility.
With flows as high as 66,000 gpm (15,000 m³/hr) Marelli has a pump that will fit your application.
