Slurry pumps for high viscous material

Slurry pumps for high viscous material

Slurry pumps belong to the category of volumetric pumps or positive displacement pumps, based on hydrostatic. In turn, these volumetric pumps can be classified into reciprocating piston pumps, such as piston pumps, and rotary or rotary pumps, such as peristaltic pumps, vane or gear pumps or lobe pumps. Lobe pumps stand out for their reliability and low maintenance cost, with numerous applications. This type of pumps represent an excellent choice when we need to transport highly viscous fluids, such as oils or sludge, with optimum performance.

Transport of high viscosity fluids
Viscosity can be defined as the resistance of a fluid to the deformations produced by shear or tensile stresses. With high temperatures, the internal friction decreases, while at low temperatures, the fluid will be more viscous. If when acting on the fluid, the cutting or traction forces cause a movement at a constant speed, we are talking about Newtonian fluids. Water is the best example of this kind of fluid, but also gasoline, wine and some oils can behave in this way under normal pressure and temperature conditions.

Knowing the specific viscosity and shear resistance of each fluid is decisive when choosing the industrial pump with which we are going to work. If you are thinking about renewing your business with a new pump, it is always advisable to consult a specialized sludge pump manufacturer, who can help you to choose the most appropriate solution for your sector and type of activity, from big industrial lobe pumps to small slurry pumps.

Industrial slurry pumps
Slurry pumps, as you can find in the Boyser company, designed for industrial use are capable of working with flow rates from 10 to 120 cubic meters / hour, for working pressures of up to 10 bar and fluids of up to 100,000 cPs of viscosity. In addition to being self-priming and reversible, these pumps offer a high resistance to abrasion, with easily replaceable wear plates.
Among the main applications of industrial slurry pumps are the treatment of wastewater, sludge, sludge, marine spills or contaminated water. It is also widely used in the food industry, as they are ideal for the transport of products such as wine, oils and molasses, glucose or tomato concentrate. Rotary lobe pumps are also a good choice if you need to work with detergents, inks, paints, glues or glycerines.

Sanitary lobe pumps
These industrial pumps are built to offer optimum performance with high viscosity fluids. All parts of the pump in contact with the fluid are made of stainless steel, to improve its resistance. In addition, they have sanitary connections standardized worldwide. Regarding its technical specifications, these lobe pumps are suitable for working pressures of up to 12 bar, with flow rates from 500 to 40,000 liters / hour.

For what type of fluids are sanitary lobe pumps indicated? These rotary pumps are a perfect solution for transporting cosmetics, shampoos, gels, toothpaste, detergents or glycerin. The food industry is another of the typical sectors for the use of sanitary lobe pumps. This sector is subject to very strict hygienic controls, which require a totally aseptic treatment of the product. Lobe pumps are recommended for the transport of wine, dairy products, juices, jams and syrups, oils, chocolate, liqueurs and all kinds of creams.
