Bredel hose pumps eliminate the all too familiar problem of pumping ceramic slip in the ceramics industry. Slip consistency must be maintained at correct levels for production efficiency and product quality but the abrasive nature of the ceramic slip can be quite a challenge for most pump types. Unlike conventional pumps, the SPX hose pump handles abrasive, corrosive or viscous fluids without damage to the working parts of the pump. Peristaltic hose pumps are virtually maintenance free with no expensive impellers, liners or mechanical seals to replace, no check valves to clog and no rotors and stators to wear out. The SPX hose pump can run dry in complete safety and has rugged 24/7 continuous duty dependability. Fast easy maintenance eliminates costly downtime. Source: Watson-Marlow
