Flowserve Loop Reactor Circulating Pumps – API 610

Horizontal circulation pumps designed for polymer loop reactor service in petrochemical plants.

These pumps are typically used in polypropylene and polyethylene production units, where high circulation flow is required inside the reactor loop.

The pumps have already completed the major machining and fabrication phases and can be finalized according to the purchaser’s requirements.

Condition

Major manufacturing activities have already been completed, including the production and machining of the main cast components of the pumps. Both raw castings and machined cast parts are available and stored in controlled conditions.

The pumps are at an advanced manufacturing stage, allowing the final configuration and finishing details to be defined according to the purchaser’s specific technical requirements.

Final assembly and completion of the pumps can be carried out within approximately 16 weeks from order, depending on the final configuration requested by the purchaser.

This represents a significant reduction compared to the typical manufacturing lead time of approximately 18 months for new pumps of this type.
