Brand: Durco
Description:

With pump ends conforming to ISO 2858 and ISO 5199 design criteria, the Durco Mark 3 ISO Close Coupled Chemical Process Pump provides a compact, space-saving solution for demanding industrial applications. This overhung centrifugal pump combines the proven hydraulic performance of the Mark 3 ISO with a close-coupled motor arrangement, eliminating the need for pump-to-motor alignment and separate baseplate installations.

Engineered for the safe transfer of corrosive, toxic, or aggressive fluids, this pump is ideal for chemical processing, wastewater treatment, and industrial utilities where reliability and footprint matter. The close-coupled design also reduces installation cost and simplifies maintenance without sacrificing performance or standardization.

The pump is fully compliant with ISO standards and offers Flowserve’s trusted durability for continuous-duty applications in harsh operating environments.

Close Coupling eliminates influence of the baseplate and foundation on alignment.

External Impeller Adjustment Mechanism uses micrometer on coupling so measurements are not needed.

Heavy-duty Casing with integral foot and multi-ribbed discharge flange offers superior resistance to pipe loads.

Reverse Vane Impeller offers repeatable pump performance throughout the life of the pump.

SealSentry Seal Chamber extends seal life and provides advanced self-flushing capability.

Back Pullout Design allows removal of rotating element without removing the casing or the piping.
