Flowserve expands capabilities of ISO standard chemical pumps

Flowserve announced the launch of its expanded range of Durco Mark 3™ ISO chemical process pumps. The Durco Mark 3 ISO pump range is fully compliant with ISO 2858 (dimensional) and ISO 5199 (design) criteria.  With flows to 1400 m³/h /6160 US gpm, heads to 220 m /720 ft and operating temperatures from -80 C to 400 C (-112 F to 752 F), the Durco Mark 3 ISO pump is available in 45 sizes, plus many designs, configurations and material combinations.

The new pump offers increased reliability through its heavy-duty casing, large radial and thrust bearings and SealSentryTM seal chamber. A range of impeller options is available. The Durco signature “reverse vane” impeller can offer significant benefits, including ease of maintenance and repeatable pump performance throughout the life of the pump.

Cost-effective maintenance can be achieved via its back pullout design, two-piece bearing housing, micrometer-style impeller adjustment mechanism and high degree of parts interchangeability.

Each Durco Mark 3 ISO pump is supplied with the new IPS Beacon™ condition monitoring unit. Mounted on the bearing housing, this battery-powered device provides a clear visual indication if temperature or vibration levels exceed pre-set limits.
