How to Choose Best Slurry Pump ?

Here are some key considerations to guide your selection process when choosing the best slurry pump for a specific application:

Application Requirements: Understand the specific requirements of your slurry pumping application. Consider factors such as the type and characteristics of the slurry (e.g., particle size, density, viscosity), required flow rate, total head, and the distance over which the slurry needs to be pumped.

Pump Type: Different types of slurry pumps are available, including centrifugal pumps, submersible pumps, and positive displacement pumps. Each type has its advantages and limitations. Centrifugal pumps are commonly used in slurry applications due to their efficiency and ability to handle high flow rates. Submersible pumps are suitable for pumping slurries from submerged locations. Positive displacement pumps can handle high-viscosity slurries or those containing large solids.


Construction Materials: Slurry pumps need to be constructed with materials that can withstand the abrasive and corrosive nature of the slurry being pumped. Consider the compatibility of the pump's wetted parts (impeller, volute, casing) with the slurry composition. Materials such as high-chrome alloys, rubber, or polyurethane may be used for wear resistance

Solids Handling Capability: Evaluate the pump's ability to handle solids present in the slurry. Look for features such as large passages, agitators, or special designs that prevent clogging or excessive wear.

Efficiency and Operating Costs: Consider the pump's efficiency to ensure optimal energy usage and lower operating costs. Look for pumps with high hydraulic efficiencies and consider the power requirements for your application.

Manufacturer and Reputation: Choose a reputable manufacturer with a track record of producing reliable and high-quality slurry pumps. Consider factors such as after-sales support, warranty, and availability of spare parts.

Maintenance and Serviceability: Assess the ease of maintenance and serviceability of the pump. Look for features such as easy access to components, replaceable wear parts, and availability of maintenance guidelines.


Budget Considerations: Consider the upfront cost of the pump as well as the long-term operating and maintenance costs. Balance the initial investment with the expected performance and durability of the pump.

Pump Size and Capacity: Consider the physical size and capacity of the pump. Ensure that the pump's size and flow capacity match the requirements of your application. Oversized or undersized pumps may lead to inefficiencies or operational issues.


Pump Head and Pressure: Evaluate the pump's head and pressure capabilities. The pump should be able to provide sufficient pressure to overcome the resistance in the pipeline system and deliver the slurry to the desired location.

Sealing and Leakage Prevention: Slurry pumps operate in demanding conditions, and proper sealing is crucial to prevent leakage. Look for pumps with effective sealing mechanisms such as mechanical seals or gland packing to minimize the risk of leakage.

Pump Reliability and Durability: Choose a pump that is known for its reliability and durability. Consider factors such as the pump's design features, robust construction, and the quality of materials used. A reliable pump will minimize downtime and maintenance costs.

Operational Flexibility: Assess whether the pump offers operational flexibility to adapt to varying slurry conditions, flow rates, or operational requirements. Some pumps may have adjustable impellers or speed controls to optimize performance.

Energy Efficiency: Energy consumption can be a significant operating cost when using slurry pumps. Look for pumps that are designed for energy efficiency, with features such as optimized impeller designs or variable speed drives that can help reduce power consumption.

System Integration: Consider the compatibility and ease of integration with your existing system or equipment. Ensure that the pump can be seamlessly integrated into your slurry handling system without significant modifications or disruptions.

A Comprehensive Guide to Mastering Slurry Pumping

 One of the most common questions our team of pump experts is asked is, "how do I pump slurry?"

With that in mind, our team of experts offer this useful guide to pumping slurry:


What is &#;Slurry&#;?
Slurry is a mixture of fluid, which consists of a water-like liquid and particles. Generally, the slurry acts in the same way as a thick, sticky fluid &#; moving with gravity but normally requiring pumping. 

There are two types of slurries found in these industries:

  • Non-settling slurries consist of very fine particles and will not settle to the bottom of the pipe or could settle over a very long period of time (i.e. weeks).
  • Settling slurries are formed by coarse particles; forming from an unstable mixture. It is these settling slurries that have coarse particles.

Generally, slurries are:

  • Abrasive;
  • A thick consistency, and;
  • Include high number of solids or particles.


Selecting the right slurry pump

It&#;s important that the pump you select has components that won&#;t wear with an abrasive slurry.
For example:

  • What style of pump is suitable?
  • If centrifugal, is the design and material of the impeller appropriate?
  • What is the pump constructed of?
  • Are the discharge configurations appropriate for the abrasive slurry?
  • What is the best sealing arrangement for the application?

Traditionally, centrifugal pumps are used for pumping highly abrasive slurries. Centrifugal pumps use the force generated by a rotating impeller to impact kinetic energy to the slurry.


Considerations for your slurry pump
Pumping slurry can cause excessive wear and tear on pumps and their components as the slurry can clog suction and discharge lines.
Global Pumps are the pumping experts and offer some useful tips in maintaining your slurry pump:

  • Determine the perfect combination of slow pumping (to reduce the wear), but fast speed to keep the solids from settling and clogging;
  • Lower the pump&#;s discharge pressure to the lowest possible point, and;
  • Ensure you&#;re following the basic rules of pump piping.

 

Pumping slurry can be a challenging problem, but with the correct guidance, pump and maintenance plan, you&#;ll achieve operational success.

Global Pumps range of SlurryPro pumps provide superior wear-life and a reduction in lifetime costs. Mainly used in the mining and quarry industry, these pumps are known for their ability to pump highly-abrasive, high-density slurries.
