More about Triark Pumps

Caster pumps

Caster Pump (WARRENDER, LTD.) specializes in technically advanced, hermetically sealed pumping systems. Caster seal-less mag-drive pumps are available in 18 designs with over 250 basic models. Caster is devoted to the production of seal-less magnetically coupled pumps. These Caster seal-less mag-drive pumps are built to withstand the most severe process conditions.

The latest WARRENDER sealless magnetic (mag-drive) pump designs of 20 different series (over 250 basic models) replace earlier Caster Pumps Division configurations (e.g., MCA, MCH, MC-SP, MTA, MT, MT-SP, MPA, MP). These designs include the WMCA alloy centrifugal ISO-2858, API-685, ANSI-B73.1, WMTA alloy regenerative turbine, WMRA alloy rotary vane, WMCP thermoplastic centrifugal, WMTP thermoplastic regenerative turbine, and WMRP thermoplastic rotary vane. WARRENDER, LTD allows for an easy transition from earlier Caster Pump designs to our new seal-less magnetic pump designs.

We have recently sold these pumps into the Chemical, Food, Waste Water, Solvents, Adhesives, Paints and Pharmaceutical industries.

We regularly sell pumps at up to 50% off list price.

All of our pumps are genuine manufacturer products, available from stock for all popular brands.

We also sell spares for all models at very competitive prices. We are often asked for the source of our spares. We only buy manufacturer spares from impeccable sources and offer them at enviable prices. We export to our local European offices for redistribution so delivery is never a problem.
