Have proved particularly successful in handling fluids that are abrasive, corrosive, have a high viscosity, are shear-sensitive or have a tendency to crystallise in any environment
Watson-Marlow Bredel, a manufacturer of peristaltic pumps, offers the SPX 10 and SPX 15 hose pumps specified for environmental applications.
Designed to fit 10mm and 15mm hoses respectively, the SPX 10 and SPX 15 hose pumps improved durability, reduce maintenance, and have a 30% smaller footprint than previous pumps.
At the heart of the Watson-Marlow Bredel SPX patented direct-coupled design is a strong, twin-bearing hub integrated into the pumphead.
The rotor is supported by its own bearings, whereas with close-coupled pumps the forces have to be absorbed by the gearbox bearings.
In addition, the coupling and its guard are eliminated.
The direct-coupled design results automatically in perfect alignment of the pumphead and drive, says the company. The greased-for-life pump bearings are incorporated into the cast-iron SPX pumphead, significantly reducing maintenance and set-up times.
Also, uniquely, an innovative leak proof zone has been created between the pumphead bearings and the gearbox bearings.
The time taken to change the hose has also been significantly reduced in the two new pumps by simpler hose clamping and flange design.
This simplifies maintenance and cuts life cycle costs.
The Watson-Marlow Bredel series of hose pumps offer reliable, rugged, transfer and metering to 350GPM and pressures of up to 230PSI.
They have proved particularly successful in handling fluids that are abrasive, corrosive, have a high viscosity, are shear-sensitive or have a tendency to crystallise in any environment.
These hose pumps have no seals, valves, diaphragms, stators, glands or other costly hardware to replace - only the hose requires changing, which is a simple task.
Users in chemical processing, food processing, brewing, pharmaceutical production, paper, mining, water, waste treatment and other industries have already discovered the benefits and simplicity of hose pumps.
