Sand, Sludge, & Slurry Pumps
Sand, Sludge, & Slurry Pumps
Sand, sludge, & slurry submersible pumps move slurry and water with solids from one location to another. Industrial Flow Solutions offers the design, installation, and service of high-quality submersible pumps. Our pumps offer superior performance and construction designed for tough environments and are commonly used in commercial, industrial, municipal, and residential applications.
Construction materials include high-chrome iron, hardened-ductile iron, cast iron, and cast aluminum. Our KZN, KB, KZE, and LWA series pumps all feature class H motor insulation, while the KHD/KHH, and SL series utilize class F motor insulation. We offer the following sand and sludge pumps series:

- KZN
- KB
- KHD/KHH
- KZE
- KZN-HYD
- LWA
- SL Solids
- P/S
- P/S MSHA
Applications of Slurry, Sludge and Sand Pumps
Our pumps easily handle abrasive slurries, acidic and caustic fluids, and heavy solids-laden liquids. We also offer Fahrenheit series pump versions of some sand, sludge, and slurry pumps that can handle fluid temperatures up to 200 degrees. Sand sludge submersible pumps are perfect for applications including:
- Beach construction and dredging
- Marine maintenance
- Paper mills
- Wastewater systems
- Mining and mineral processing
- Construction sites
- Power generation
- Metal manufacturing
- Dredging
- Construction

FAQ
1. What is Slurry?
A slurry is a mixture of insoluble solid particles suspended in a liquid, typically water. This mixture facilitates the transport of solids by allowing them to be pumped. Materials commonly found in slurries include cement, coal, animal waste, and sand. The size of the solid particles within a slurry can range from very fine to several millimeters.
2. How Large Can the Debris Be for a Sand or Sludge Pump?
Sand or sludge pumps can generally handle small debris. For example, our KZN370 model pumps can accommodate solids up to 1.5 inches.
3. What Is the Life Expectancy of a Sludge Pump?
Most sludge pumps will perform for about 10 years with proper maintenance and operation, sometimes much longer. However, factors including the pumping height and concentration of solids by weight can affect performance and the need for repairs.
4. Where Are Sand and Sludge Pumps Required?
Sand and sludge submersible pumps are required to move solid-containing water. Dredging operations, mining operations, and gravel pit emptying are common uses.
5. What is the Difference Between a Solids Handling Pump and a Slurry Pump?
Slurry Pumps are designed to handle a mixture of liquids and fine, abrasive particles, often referred to as slurry. They are built to withstand the wear and tear caused by these abrasive materials. Common applications include dredging and moving sand, sludge, and other fine solids.
Solids-Handling Pumps, on the other hand, are designed to transport liquids containing larger, often stringy or irregular solids without clogging. Many of these pumps are equipped with shredding or grinding mechanisms to break down materials like plastics, fibrous solids, and food waste before they pass through the pump. This makes them ideal for applications such as wastewater treatment, food processing plants, and commercial facilities where clogging is a major concern.
