Waste Water and Sewage Treatment

The simple, glandless, "straight through" construction without valves, vanes or impellers, has clear advantages in handling viscous sludges liable to contain rag type or other solids which cause blockages, while the ability to impart minimal shear, combined with the high levels of volumetric accuracy when handling additives such as polyelectrolyte, is important in terms of both efficient flocculation and additive consumption.

In the first stage, SP50 pumps run for approximately five minutes each hour and draw off sludge from the primary tank containing between 2% and 5% solids, and discharge to the top of a holding tank. Water is removed separately and goes for further treatment. An SPX50 pump running for twenty minutes in every hour, transfers the primary sludge from the holding tank to picket fence thickeners where it is constantly stirred. The sludge, by this time containing 8%, solids, is pumped from the thickening tank to a heated digester tank by an SPX80 pump, the slow speed avoiding thermal shock as cold matter meets warm

Reduced operating costs can be achieved by the installation of Watson-Marlow Bredel pumps in the feeding of primary or thickened sludge to digesters or filter presses, and in primary tank auto-desludging. To complete primary auto-desludging, following digester treatment, the sludge goes to secondary storage tanks, where polyelectrolytes are dosed by low-pressure peristaltic pumps prior to dewatering.

Bredel Hoses

Bredel`s innovative hose design and unique ground construction has created the benchmark in hose performance and life. The unique design ensures that compression forces are evenly applied, and the enormous restitutional ability of the hose creates powerful suction handling and accurate metering capabilities.

Bredel High Pressure Hose Pumps for Peristaltic Pumping

Bredel engineering created an entirely new type of pump - the high-pressure hose pump. Its patented technology achieved what was believed to be impossible: the unbeatable simplicity, reliability and low maintenance needs of peristaltic pumping brought to high-flow, high-pressure duties.

Today, 75,000 Bredel pumps are at work around the world at flow rates up to 350 gpm and pressures up to 230 psi. Hose pumps are the future, and they work. Tens of thousands of pump users know there isn`t a more rugged and reliable solution to pumping problems than a Bredel.

Bredel SPX - The Future of Hose Pumping

The unique direct-coupled design of the Bredel SPX provides all the performance, reliability and ease of maintenance benefits of bareshaft (long-coupled) designs with the compact advantages of close-coupled pumps in sizes ranging from 10mm to 100mm.

Superb engineering design from the world leaders in hose pumping has achieved the rare feat of cutting cost of ownership at the same time making use and maintenance easier than ever before. It is the future of hose pumping engineered by the people who invented hose pumping.

Unlike close-coupling, Bredel`s patented direct-coupled design permits the drive to be removed and replaced without the need to dismantle the pump head.

PetroProof Hose Pumps for Hydrocarbons, Petrochemicals and Oil Based Products

Petrochemicals, hydrocarbons, and oil based products were all beyond the reach of peristaltic pumps due to incompatibility with the rubber hose As the world leader in hose pump technology, the research and development team at Watson-Marlow Bredel is constantly investigating and testing a wide range of rubber and thermoplastic hose materials to broaden our range of applications. We`ve identified a revolutionary new TPE (thermoplastic elastomer) that matches oil resistance with the dynamic properties needed for long life in a hose pump. Designed around this material, the PetroProof pump was born and is the first peristaltic hose pump in the world capable of handling hydrocarbon liquids in continuous duty applications.

Applications

  • Toluene as solvents in the production of a myriad of materials such as gaskets or like material, aerosol spray paints, wall paints, lacquers, paint strippers, adhesives, printing ink, spot removers, cosmetics, perfumes, and antifreeze. 
  • Paints, lacquers and adhesives are commonly pumped in many markets including printing, pulp & paper, packaging, construction, manufacturing and automotive - all markets that need low flow metering! 
  • The ability to handle oil, polymers, fats, fuel oils and cleaning chemicals means this pump is perfect for applications in industrial wastewater as well. 
  • High-precision machined hose elements

At the heart of all Bredel pumps is a remarkable composite reinforced hose. The hose is constructed from high-quality compounded rubbers reinforced with four (two in the case of the SP10 and SP15 hoses) individual layers of braided nylon, and finished by high-precision machining. Because rubber is incompressible, nothing is more important to hose pumping that acurate control of the hose dimensions to ensure that the occlusion of the hose is exactly right:

- Over-occlusion of the hose stresses both pump and hose, reduces hose life, and places unplanned loads on the pump bearings.
- Under-occlusion results in loss of pump efficiency and damaging back-flow, which also reduces hose life.

In- House Hose Pump Manufacturing

Bredel is the only hose pump manufacturer to machine its own hoses, and no other manufacturer can match Bredel`s experience of configuring pump and hose to precisely meet the flow, pressure and temperature characteristics of any application.
  
Nothing but the hose or tube touches the fluid, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. The complete closure of the hose which is squeezed between a shoe and the track gives the pump its positive displacement action, preventing backflow and eliminating the need for check-valves when the pump is not running.

  • There is no contamination of the pump or fluid 
  • Ideal for slurries, viscous, shear-sensitive and aggressive fluids 
  • Easy to install, simple to operate, inexpensive to maintain 
  • Pump design prevents backflow and syphoning without valves 
  • Wide range of tubing includes industrial, food-grade and medical

Tubing and Hoses for Accurate Metering and Dispensing

Watson-Marlow Bredel pumps use either hoses which are reinforced against high pressure, or tubing which is unreinforced for lower pressure duties. For accurate metering or dispensing and for long life, both must be be made with tightly controlled formulations and dimensions. Only Watson-Marlow tubing and Bredel hoses are made for use in Watson-Marlow Bredel pumps.

Bredel Hoses Provide Powerful Suction Handling and Accurate Metering

Bredel`s innovative hose design and construction has created the benchmark in hose performance and life. The unique design ensures that compression forces are evenly applied, and the enormous restitutional ability of the hose creates powerful suction handling and accurate metering capabilities.

Watson-Marlow Tubing for Peristaltic Pump Configuration

Available in seven different materials and twenty-two different sizes, from 0.13mm to 40mm, the range of Watson-Marlow tubing enables customers to configure their peristaltic pumps for specific applications.

Watson-Marlow is unique in being the only peristaltic pump manufacturer to have its own silicone tubing plant, giving users the benefits of a short supply chain and total quality. Tubing is available in seven different materials and 22 different sizes, from 0.13mm to 40mm. The range of Watson-Marlow tubing enables customers to configure their peristaltic pumps for specific applications
 
The tubing is as important as the pump

  • Its restitution creates suction lift 
  • Its strength resists pressure 
  • Its flex resistance determines pumping life 
  • Its bore decides the flow rate 
  • Its wall thickness controls pumping efficiency

Ordinary tubing is not designed for peristaltic pumping, and only Watson-Marlow precision pump tubing will give the best results in a Watson-Marlow pump. The results of using any other tubing are unpredictable, and may jeopardise your process.
 
How to choose the right tubing material
  
The best way to select a tube is to first decide which materials are chemically suitable, and then choose the one which best meets the physical demands of the application. For maximum tube life, use a large bore tube at low speed. For maximum flow rate use the largest tube at maximum speed. For maximum accuracy, use a small bore tube at maximum speed.

Suction lift depends on the tube restituting fully before the advance of the next roller. If it does not, the flow rate will be reduced. For maximum suction lift or pressure, use the smallest practicable bore size of tubing and run the pump at the slowest possible speed. Always make an immersion test before choosing a tube material for critical applications. Immerse a short length of the tubing (always available from Watson-Marlow Bredel or its distributors) in a closed container of the fluid for 48 hours, and then examine it for signs of attack, swelling, embrittlement or other deterioration.

Pumpsil Platinum-Cured Silicone Tubing with Unique LaserTraceability

Successful peristaltic pumping depends utterly on the quality of the tubing. That`s why Watson-Marlow has invested in its own class-J clean room and computer-controlled extruders to produce the world`s finest pharmaceutical-quality platinum-cured silicone tubing with:

  • Complete USP Class VI, FDA and NSF validation pack 
  • Polished dies produce ultra-smooth surfaces 
  • Laser and ultrasonic tolerance control for precision performance
