Top 8 Considerations for Selecting a Slurry Pump
Choosing the right slurry pump for your application involves several critical factors. Unlike standard pumps suited for thinner fluids, slurry pumps need careful consideration due to the unique characteristics of slurries, which include varying viscosity and high solid content. An incorrect selection can lead to inefficiencies, or worse, pump failure, resulting in costly downtime.

- Understand the Material Being Pumped
The type and characteristics of the fluid to be pumped are crucial. Factors to consider include:
- Viscosity, usually measured in centipoise (CPS).
- Density, commonly indicated as specific gravity (Sg).
- pH level of the fluid.
- Static and operating temperature.
- Pump Flow Rate
The flow rate requirement is another consideration. The pump must exceed the necessary flow rate for effective operation. Additionally, understanding the critical flow rate—necessary to keep solids suspended in the slurry—is vital to prevent clogs.
- Materials of Construction
Slurry pumps must be made of materials that are chemically compatible with the pumped fluid to avoid catastrophic failures. Furthermore, they should withstand the abrasive nature of slurries to prevent premature wear of components.
- Inlet and Discharge Pipe Considerations
Pipe specifications such as length, diameter, and material can significantly affect pump performance. Properly sized pipes reduce discharge head pressure while maintaining adequate flow velocity, crucial for preventing clogs.
- Motor Power
The motor's horsepower is critical, especially when pumping viscous slurries. The motor must possess enough power to overcome downstream hydraulic losses due to bends and elevation in the discharge piping.
- Pump Operating Cost
Operating expenses for a slurry pump can be substantial, influenced by energy demands and the capability to pump viscous materials with reduced accompanying fluids. Selecting an efficient pump can save significant costs.
- Pump Elevation
Carefully choose the pump's location to avoid problems with priming and flow rate. Placement affects the pump's ability to draw in the fluid, impacting overall efficiency.
- Pump Orientation
The pump's orientation can affect its suitability for specific tasks. Horizontal pumps are favored for most applications, but vertical options may be necessary for tighter spaces.
