Peristaltic pumps from Watson Marlow Fluid Technology Group are increasingly favoured for concrete washout applications, due to their low maintenance requirements, and safe, non-contacting pumping method.
Without mechanical seals or valves to leak or corrode, Qdos and Bredel pumps completely contain the pumped fluid, preventing operator contact with chemicals, or spillage of untreated sludge, says the company.
Importantly, peristaltic pumps do not require skilled personnel for maintenance. A simple Qdos ReNu pumphead or Bredel hose change takes only minutes and can be performed on site.
Their low cost maintenance adds to the list of reasons that growing numbers of plant contractors are turning to WMFTG pumps for chemical dosing and sludge transfer duties in the final stages of pH adjustment and treatment of concrete wash water.
Clean, pH-adjusted and sediment-free water can then be re-used on site, for tanker and conveyor washout, providing further cost savings.
Construction waste such as concrete washout is under scrutiny from environment agencies around the world, largely due to its heavy-metal content, notably chrome.
Watson-Marlow’s latest Qdos chemical metering pumps and Bredel hose pumps are highly proven in tough applications such as construction sites, aggregate and concrete production plants.
