Learn more about the types of slurries, what to consider when selecting a slurry pump, and the numerous slurry pump applications across industries.

What Is Slurry?

Slurry is composed of solids suspended within a liquid. This fluid can vary in viscosity from thin to thick, with different temperatures and suspended particle sizes. Unlike pure water, transporting slurries can lead to corrosion and abrasion in pumping equipment.

There are countless substances considered slurries. Some slurries are intentional, like foods, paints, and cement, while others must be managed, like pond muck or wastewater.

Common varieties of slurries include:

• Soil slurry: A mixture of mud, clay, dirt, sand, silt, rock, and other soil particles in water, effectively moving the soil media.
• Coal slurry: A toxic byproduct of burning coal for energy production, composed of water and coal fly ash.
• Slurry oil: A byproduct generated through fluid catalytic cracking (FCC) in refineries, contributing to the international fuel oil supply.
• Pulp slurry: Utilized in paper production, derived from solvents and various wood pulps.
• Manure slurry: Composed of organic matter and animal waste, used as fertilizer in agriculture.
• Wastewater: Contaminated water that humans have used, typically referring to sewage wastewater.
• Sewage sludge: A semi-solid byproduct of sewage wastewater treatment.
• Food processing slurry: Liquefied processed foods with a solid base such as peanut butter, soups, gelatins, and condiments.

Considerations When Choosing a Slurry Pump

Given the numerous varieties of slurries, there are also many sludge pump types available. Choosing the wrong pump can lead to reduced suction effectiveness at best, and at worst, equipment damage, system downtime, and costly repairs or replacement parts. To select the right slurry pump for your application, consider five key variables:

Design

Since many slurries are corrosive and abrasive, it is crucial to choose a pump with a durable impeller or rotor. Slurries may contain particles of varying sizes and densities, so select a pump design that minimizes the risk of clogging.

The GATOR Sludge Pump features a modification with an in-line slurry valve that facilitates media pumping and handling by using discharge flow to agitate and thin the fluid. After processing, the valve closes, and the sludge removal pump transports the material to the discharge point.

Materials

The construction materials of a slurry pump directly impact its effectiveness and longevity. For abrasive slurries with a neutral pH level, Hi-Chrome is the preferred material due to its high Brinell hardness.

For abrasive slurries with an acidic pH, duplex stainless steel is recommended. This material also maintains a high Brinell level suitable for handling corrosive materials.

Deployment Technique

A slurry pump's deployment method is critical to its setup. GATOR Pump offers submersible pumps, which completely submerge in a liquid. Since these pumps are submerged, they require no priming, suction lines, or check valves.

Power & Size

The application of a slurry pump determines its power needs and size. The ideal operational speed for slurry pumps typically ranges from 900 to 1,200 RPM to optimize longevity and efficiency. Operating at slower speeds avoids excessive wear, similar to sandblasting, that occurs when RPM exceeds this range.

What Industries Use Slurry Pumps?

Slurry pumps are used in various industries:

Irrigation & Agriculture

Portable sludge pumps are ideal for agriculture, enabling the movement of large quantities of water from ditches, canals, streams, or ponds. Key applications include:

• Weed and water-grass management
• Animal waste removal
• Sediment removal during pond cleaning

Mining & Construction

Mining and construction sites require continuous flow, and pumps must withstand abrasive and corrosive media. Our pumps effectively handle these slurries in applications like:

• Storm deluge and emergency flood pumping
• Gravel and sand quarry dewatering
• Settling pond containment and water transfer

Wetland & Waterfowl Management

Reliable slurry pumps are essential for land conservation to protect wildlife habitats and wetlands. Our pumps support environmental management through:

• Flooding wildlife habitats for fishing and hunting
• Mitigating storm surge
• Dewatering for seasonal habitat preparation

Flood Control Drainage

Timely deployment of reliable flood pumps is crucial in addressing flooding in residential, business, and agricultural areas. Our slurry pumps manage:

• Wildlife and fish refuge management
• Sewage bypass and stormwater removal
• Emergency response pumping in remote areas

Sludge, Slurry, & Manure Waste Handling

When pumping manure or slurries, compliance with regulations is essential. Our pumps meet the necessary standards for various environments:

• Transfer pumping for sewage plants
• Manure lagoon management
• Handling landfill leachate

Oil Fields, Refining, & Energy

Slurries are prevalent in the petroleum industry, some of which are highly abrasive and thick. Our pumps can maintain consistent flow in applications such as:

• Drill mud handling
• Oilfield water and mud injection
• Refinery fire suppression

Top 8 Considerations for Selecting a Slurry Pump

Top 8 Slurry Pump Considerations

This list outlines eight considerations for choosing a slurry pump best suited for your application. Selecting a pump for a slurry application is more challenging than for thinner fluids. Mistakes in the selection process can hinder performance or make the pump ineffective for moving higher viscosity, abrasive, solid-laden fluids, rendering it useless.

1. Know the Material or Fluid Being Pumped
   • Fluid viscosity, usually measured in centipoise (CPS).
   • Fluid density, typically measured as specific gravity (Sg).
   • The pH level, measuring hydrogen-ion concentration.
   • Static and operating temperature of the fluid.
2. Pump Flow Rate
   • The flow rate must exceed the required rate to ensure optimal performance (e.g., 350 GPM or 200 cu. yards per hour).
   • The pump's flow rate should surpass the critical flow rate, necessary for maintaining suspended particles and solids in the slurry.
   • Flow velocity is critical; the material must move consistently to avoid settling and clogging.
3. Materials of Construction

   The pump must be chemically compatible with the liquid to avoid catastrophic failure. Additionally, it should withstand the abrasive nature of the fluid.

4. Inlet & Discharge Pipe Considerations
   • Pipe length and diameter affect fluid buildup and the power required for pumping.
   • The diameter should reduce discharge head pressure while maintaining sufficient velocity to prevent clogging.
   • Pipe material must be chemically compatible and should minimize friction losses with a reduced surface finish.
5. Motor Power

   Motor power, indicated in horsepower (HP), is crucial for pumping slurries with high viscosity and specific gravity. It must also overcome discharge piping forces.

6. Pump Operating Cost

   Consider the economic impact of operating the pump, including energy costs and the fluid required to pump viscous materials.

7. Pump Elevation

   Ensure the pump is not positioned too high above the fluid source to achieve effective priming and flow rates.

8. Pump Orientation

   Pumps come in various orientations. Horizontal pumps are most common, but vertical pumps may be better for limited spaces.
