Watson-Marlow Bredel APEX pumps

APEX pumps from Bredel are designed to suit all dosing, metering and transfer applications from 2.8 to 1200 L/h across a broad range of applications for processing plants.

With cast aluminium housing providing good heat dissipation, robust direct-coupled technology and precision machined hose elements, the pumps provide low maintenance, operation and inventory costs, extending uptime and process continuity.

While the product provides optimum performance for low flow transfer applications, should process requirements change, easy upgrades are achievable without having to buy a new pump. This is because the model is three pumps in one, with a single pump body adjustable for three hose sizes (10, 15 and 20 mm) when production volumes rise.

The pumps are claimed to offer the best performance on the market for pressures up to 8 bar, along with reliable and stable flow up 1200 L/h (with 20 mm diameter hose), making them suitable for ongoing, precise dosing. This is boosted by long-lasting hoses that also support repeatable accuracy when dosing additives, while continuous pump speeds up to 100 rpm provide a wider capacity range in comparison with alternative hose pumps.

The performance of the pumps means they are suited to applications ranging from lime dosing and slurry transfer, through to handling food and beverage products. Unlike other pump types, hose pumps have no expensive wearing components such as seals, valves, membranes, stators, rotors or glands. Subsequently, they are suitable for handling ‘difficult’ fluids - abrasive, corrosive, viscous, shear-sensitive, crystallising or even fluids presenting a combination of these properties.
