Durco was founded in 1912. Durco is recognized as an innovative flow-control brand whose comprehensive portfolio of pump and valve products are all designed to handle the most difficult and demanding applications.
Flowserve Durco Guardian sealless pump technology offers superior, leak-free performance in the most demanding services. Compliant with ASME (ANSI) B73.1-2001 dimensional standards, the Guardian magnetic drive pump is designed for simplicity and reliability in even the toughest emission-free services.
The all new Durco Mark 3 Group 4 pump offers increased capacity with proven Durco performance and reliability along with ASME B73.1 design features. Offering flow rates to 3861 m3/h (17 000 US gpm) — well beyond ASME size limits — the Durco Mark 3 Group 4 is ideal for high-flow, high-head applications in the chemical processing and general industries.
The Durco Mark 3 ISO chemical process pump provides unmatched performance and reliability, conforms to ISO 2858 and ISO 5199 design criteria and incorporates advanced design features. The ruggedly designed Durco Mark 3 ISO offers significant operational and maintenance enhancing benefits that help users to minimize the total cost of pump ownership.
Durco Mark 3 chemical process pumps provide outstanding hydraulic performance, unrivaled reliability and low total cost of ownership. Conforming to ASME (ANSI) B73.1, Durco Mark 3 pumps incorporate many proven reliability- and performance-enhancing features. They are available in a wide range of configurations, including mechanically sealed, dynamically sealed, sealless magnetically driven, low-flow, self-priming and recessed impeller. It provides flexibility and breadth of pumping solutions in countless applications throughout the worldwide infrastructure markets.
The PolyChem GRP pump is a single-stage, end suction, centrifugal pump designed to ASME B73.1 standards. This product is constructed in Glass Reinforced Phenolic (GRP), which offers a cost-effective means of corrosion resistance as a more expensive high-alloy metal pump at a fraction of the cost. The PolyChem GRP pump has proved to be a cost-saving, long-term solution in acidic, chloride-rich and salt water applications.
The PolyChem S-Series chemical process pump features a fluoropolymer-lined, conventionally sealed design and meets ASME B73.1 dimensional standards. The PFA-lined wet end provides superior corrosion resistance and temperature allowance. Incorporating the proven Mark 3 power end, the PolyChem S-Series pump is engineered to maximize performance and reliability.
