Transfer abrasive and corrosive sludge and slurry efficiently and easily with the Multotec range of industrial sludge pumps.
Our sludge transfer pumps are ideal in a wide range of heavy and medium-duty applications, from slurry transfer (cyclone, spirals and filter feed, mill discharge) to tailings disposal, mine dewatering, effluent discharge and more.
Across industries – from mineral processing and mining to construction, wastewater treatment and more – operators are choosing Multotec’s superior quality sludge pumps to meet their needs efficiently, reliably and cost-effectively.
Mining customers around the world use our superior range of solids handling centrifugal pumps. The range is made up of horizontal, vertical and submersible sludge pumps used across all service classes.
When looking for a sludge pump for sale, Multotec will work with you in specifying the type, design and capacity of your pump according to slurry weight, concentration, abrasivity and throughput requirements.
The use of Multotec sludge pumps isn’t limited to a specific sector, but used across a vast range of industries, such as:
Mines and mineral processing plants are harsh environments, with large amounts of aggressive and abrasive slurry that must be transported to various applications for further processing or for discharge.
Multotec’s sludge pumps for mineral processing and mining are designed to withstand the heavy duty demands of these industries.
In the construction industry, ground water must be removed and both sludge and wastewater need to be diverted for treatment and reuse or discharge. Multotec’s sludge pump design and flow rates cater to the many pumping requirements of this industry.
Most paper mills have their own wastewater treatment plants and, as sludge is a by-product of the paper manufacturing process. Multotec sludge pumps are ideal in removing this slurry.
Sludge, generally associated with industries like steel processing, mining, power generation, mineral processing, cement, etc., is heavy and can contain corrosive, abrasive or volatile content. Because sludge behaves much the same as thick and viscous fluids, a powerful pump that processes and moves waste fluids with high solid content is necessary.
Sludge is divided into two distinct categories – settling and non-settling. In settling sludge, coarse particles form which can lead to an unstable mixture. Because of the flow and power required with pumping, it is essential to select the appropriate pump. Non-settling sludge consists of fine particles with low-wearing properties. However, it is also important to select the most appropriate pump for this category.
Multotec will work with you in specifying the type, design and capacity of your pump according to sludge weight, concentration, abrasive characteristics and throughput requirements.
There are many and varied sludge pump types. In selecting one, it is necessary that the sludge to be pumped be classified. Sludge and slurry classification is more than just its measuring solids concentration. In addition to the concentration of solids, classification criteria include measuring solids’ particle size, shape and weight. This information is used to determine slurry and sludge abrasion severity and, subsequently, classify the sludge as class 1, class 2, class 3 or class 4.
There are ongoing changes in slurry pump design and construction in order to accommodate the various sludge types. The numeric sludge classification method assists plant managers when selecting the pump for a specific application. In determining the most appropriate slurry pump to meet all requirements, engineers, plant managers and pump operators must consider pump capacity, head, solids handling capacity, efficiency, power and speed.
Multotec’s pump technicians and engineers are experts in their field and use their years of experience along with the latest software to ensure you get the correct pump for your classified sludge.
The impeller’s peripheral speed is a main feature, and classification component, of sludge pumps. Due to the high abrasion of solids, is important that the speed is according to the correct classification type (class 1, 2, 3 or 4), which will aid in the pump achieving its desired service life.
The terms sludge and slurry are often interchanged, although there is a difference between the two.
They are differentiated by their texture and components. Both are by-products of industrial, wastewater treatment or refining processes, and both are defined as wet mixture of solid and liquid components. The primary difference is that sludge is thick and soft while slurry is thin and sloppy.
Each can contain biosolids or other debris, mud, oils and non-hazardous water, and both can be packaged in drums, stored in holding tanks or intermediate bulk containers.
However, as the products are different and contain different contaminants, they should be dealt with slightly differently
If there are contaminants in either of these products, they should be removed in either a dewatering or a filtration process. The filter cakes resulting from this process may be contaminated or have biosolids containing organic matter. The composition of filter cakes determines whether they can be reused or disposed of. Either way, the remaining water must be treated again in a process optimised for recycling and reuse.
Multotec’s range of 6 various sludge pumps means we have the ideal pump for all of your slurry and sludge applications.
