Siltbuster Ltd, a nationwide specialist in the supply of water treatment solutions for the construction, municipal and industrial sectors, reports that a number of recent tough applications have seen its preferred Bredel hose pumps tested to the full

Pumping kieselguhr and transferring crude oil are among the extreme tasks that Siltbuster has recently encountered, highlighting that there really is virtually no limit for these robust and reliable hose pumps.

Since the launch of the original Siltbuster unit in May 2003, this forward-thinking company has become the UK’s leading authority on water treatment, wet waste and the prevention of waterborne pollution from construction and industrial sites.

Among the 40-employee company’s solutions is a range of equipment for silt management and the prevention, control and treatment of water contamination.

“We’ve been using Bredel pumps in our solutions for a number of years and have amassed quite a number,” explains Project Engineer Alex Spyropoulos.

“Sludge transfer on DAF (dissolved air flotation) units is a good example of an application where we have extensive numbers of Bredel pumps in action. Here, we use Bredel 25, 40 and 50 heavy duty hose pumps to help manage sludge production. Bredel pumps produce much higher pressure on the discharge side, which also makes them favourable over electric diaphragm pumps in applications where there is a steep gradient or deep tank. The fact that they are self-priming offers additional process benefits over some alternative pump technologies.”

Pushed to the limit
Mr Spyropoulos can also recall a couple of recent applications where the product being pumped tested Bredel”s hose pump technology to its limits.

“One of the applications I have witnessed involved a switch from a progressive cavity pump to Bredel hose pump at a brewery which had keiselguhr (diatomaceous earth) amongst other difficult media in the sludge. It proved to be highly abrasive on the PC pump but the Bredel managed very well.  This, in addition to the fact the Bredel units are able to handle a considerable volume of sludge means we consider this technology to be ‘tough’ and fit for purpose.”

Elsewhere, Mr Spyropoulos recounts an application at a refinery, where Bredel 50 pumps were deployed to pump crude oil.

“Pumping crude oil is a very aggressive application so we used Bredel CSM hose elements to ensure chemical compatibility and good hose life,” he says.

In applications such as these, the selection of hose elements is critical to ensure pump performance and durability. Bredel CSM composite reinforced hoses are constructed from high quality compounded rubbers reinforced with four individual layers of braided nylon, and finished by high precision machining.

Watson-Marlow Fluid Technology Solutions

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.
