Bredel hose pumps (10-50)
Bredel hose pumps have no valves or seals to leak, clog or replace and provide flow rates to 17,520 L/h and pressures to 16 bar.
They can pump viscous and abrasive slurries, pastes and sludge, with up to 80 % solids in suspension.
Unlike other pump types, the highly abrasive nature of grit-filled sludge or lime slurry in the environmental market, does not affect peristaltic hose pump life.
Bredel hose pumps eliminate ancillary equipment such as dry run protection, seal water flush systems and in-line check valves. They are also reversible to flush lines.
Features and benefits
- Dry running and self-priming
- Suction capability up to 9.5 mWC (354 inWC)
- No seals, ball-checks, diaphragms, glands, immersed rotors, stators or pistons to leak, clog, corrode or replace
- Handles abrasive slurries, corrosive acids, gaseous liquids
- No slippage, allowing true positive displacement for accurate, repeatable metering
- No ancillary equipment, check valves, sealing water flush systems or run-dry protection required
- Fully reversible to blow out suction and drain lines safely
