HMD Kontro GSA/GSI General Service Pump

General Service Pump – GSA/GSI

Engineered ASME / ISO pumps for more challenging pump applications

A versatile range of general service sealless pumps designed to cover a wide duty and application base with maximum interchangeability. The range includes the GSA designed to ASME B73.3 standards and the GSI designed to ISO 2858 / 15783 standards providing an easy upgrade path for existing installations.

The GSA/GSI is offered with a range of engineered options including secondary systems, heating / cooling jackets, filtration and various materials of construction to meet the needs of the most challenging pumping applications.

Key Design Features:

Sealless Design: For total product containment, essential for hazardous, aggressive or valuable liquids
No Seals: Minimises maintenance and all of the associated costs and eliminates potential leak paths
Maximum Flow & Head Coverage: Providing optimum hydraulic performance for a range of pump duties.
Various Materials of Construction Available: 316 Stainless Steel as standard with Alloy 20, Alloy C276, Duplex Stainless Steel and other materials available on request to provide optimum levels of corrosion resistance.
Engineered Options Available: Providing suitability for a range of pumping applications, including jackets, filtration, extended temperature designs and secondary control / containment.
