SPX50 hose pumps from Watson-Marlow Bredel have been found suitable by an Australian pool builder for pumping pebblecrete in pool finishing works.
Pool Concepts constructs durable steel-reinforced concrete swimming pools catering primarily for the top end of the residential market as well as commercial pools and water features.
As part of an equipment upgrade drive to upscale their capabilities, the company decided to replace their ‘pebble pump’ used to pump pebblecrete and specialised pool renders on pool interiors.
Pebblecrete has a high ratio of cement to natural pebbles up to 3mm in diameter in addition to abrasive white quartz sand. The company needed a solid, reliable hose pump to pump this abrasive mix with each pool requiring on an average, 1.5 tonnes of pebblecrete pumped through a 40mm rubber hose over distances of up to 60m to a spray nozzle at the end of the hose for spraying onto the pool walls and floor.
Shane Elliott, one of the two directors of Pool Concepts explained that the company was previously using a Condor mortar pump modified to suit their needs, but the pump sleeves were lasting as little as six to eight weeks and were very difficult to obtain.
Following considerable research, the company decided to invest in a Bredel SPX50 hose pump that would be connected to their mixing hoppers.
Key features of Bredel SPX50 hose pumps:
- Abrasion resistant reinforced hoses are machined to very tight tolerances, ensuring no slip
- Allows small hard solids to be easily pumped
- Run dry protection with no shaft seals
- Direct-coupled design delivers a small footprint
- Powered by hydraulics from the truck’s PTO (power take-off unit) for quieter and more efficient operation
- Compact, truck mounted pump allows room for enough pebble and cement to complete two pool interiors
