· Bredel 65 pumps replace troublesome progressive cavity (PC) pumps
· Reduction in maintenance allows return on investment in just 12 months.
· NR Endurance hoses provide impressive lifetime handling abrasive sludge
Celje is the third largest city in Slovenia and sits at the junction of the Savinja, Hudinja, Ložnica, and Voglajna rivers in the lower Savinja Valley.
Serving a population of 85,000 people, the city’s waste water treatment plant (WWTP) used two progressive cavity (PC) pumps to feed a centrifuge with settled sludge.
The abrasive nature of the sludge meant that the PC pumps suffered stator and rotor wear, leading to a drop in flow rates, as well as the need for regular maintenance downtime. Maintenance often took several hours to complete and required expensive spare parts.
To reduce costs in the Celje WWTP sludge handling duty, Watson-Marlow Fluid Technology Group recommended two Bredel 65 peristaltic hose pumps, fitted with abrasive-resistant NR Endurance hoses, as replacements for the troublesome PC pumps.
Bredel hose pumps have no seals, diaphragms, glands, immersed rotors, stators or pistons to leak, clog or wear. And, unlike other pump types, viscous, grit-filled sludge does not affect their performance. The hose is the pump; a single component change is usually the only maintenance required, with time to change a hose measured in minutes rather than hours.
Bredel’s NR Endurance hoses are providing an impressive lifetime of between 10 and 12 months, significantly reducing the need for maintenance downtime, enabling the waste water treatment plant to achieve a return on investment in just 12 months.

About us
Watson-Marlow Fluid Technology Group (WMFTG) peristaltic tube and hose pumps meet requirements including: value for money; low cost of ownership; reliability and ease of maintenance to the food and beverage, chemical, pharmaceutical, mining and many other industries.
We demonstrate how pumps deliver significant process efficiencies over the lifetime of the equipment. Whether performing flavouring addition in food processing, chemical metering in water treatment or mineral recovery, we have a solution which can cut pump downtime and reduce costs through higher accuracy metering and transfer. WMFTG has dedicated application engineers available to help customers make the right pump and tubing choice from a range providing microlitres per minute to 80 cubic metres per hour flow rates.
The only part of the pump to come into contact with the product is the tube or hose. This means there are no seals or valves that can wear or fail. Replacing the tube or hose can be performed quickly and safely. Peristaltic pump benefits include:
Total fluid containment with no seals No ancillaries Handle viscous and abrasive slurries and sludge Self-priming capability Dry running without damage to the pump In addition to their range of positive displacement pumps, Watson-Marlow Fluid Technology Group has added PTFE-lined chemical and industrial hoses to their range. Aflex hoses are reinforced to withstand the most severe conditions and use.
