Keeps High Solids Slurries Mixed and Transfers With Ease


Keeping viscous slurries mixed helps prevent the settling of high solids sludge and slurries with low downtimes

The EDDY Self-Priming Slurry Mixing and Transfer Pump incorporates a vacuum-assisted priming slurry pump, a slurry container, a suction/discharge hose, and a recirculation hose. These components work in conjunction allowing for the EDDY Pump to continually mix the slurry within the slurry storage container, keeping it from settling, allowing for easy slurry transfers to a truck or another disposal means.

Most EDDY Pumps are submersible, however, with a self-priming unit, the pump and power unit are not submerged. The suction hose goes into the slurry and the unit acts like a super-sized wet vacuum.

Self-Priming Pump = Cost Savings

For example, a recent client in the manufacturing space was paying over $200,000 every year for vacuum truck companies to frequently come out and collect the waste in their sumps. To combat the rising costs, they tried using other pumps but there was a high failure rate because of large debris and abrasive slurries which would clog the pump, creating maintenance and downtime issues.

This was solved with a 2-inch self-priming EDDY Pump for less than 10% of the annual vacuum truck costs!

Pump Applications That Will Benefit From an EDDY Self Priming Pump

Manufacturing: Large pits or sumps collect all the waste, sludge and wash off from the manufacturing processes. This material is often laden with multitudes of chemicals, abrasive debris and solids which can quickly wear down traditional pumps.

Paper/Pulp Production: Concrete sumps and basins are frequently filled with caustic chemicals and chunks of trees and bark as part of the paper manufacturing process.

Oil/Gas/Drilling: Drilling mud pumping and drill cuttings from tanks and waste disposal ponds often need to be cleaned out and removed off-site.

Dewatering: Some of the most common dewatering techniques involve submersible dewatering pumps, siphoning, or using large machinery buckets to catch the water and dump off-site. These techniques are performed when the water that needs to be removed is below the designated discharge area.

Fundamentally, the main motivating factor to switch to a self-priming pump unit is to save on costs. By running some quick numbers, you should be able to quickly determine if your company can save money by converting existing systems to a self-priming unit.

What is a self-priming pump?
A self-priming pump is a type of pump that has the ability to prime itself without external assistance automatically. It utilizes a mechanism to evacuate air from the suction line and create a vacuum, allowing it to draw fluid into the pump casing and begin pumping.

What is the working principle of a slurry pump?
The working principle of a slurry pump involves converting rotational energy from a motor into hydraulic energy to transport abrasive or viscous fluids, known as slurries. This is achieved by using an impeller that rotates within the pump casing, creating a centrifugal force that propels the slurry through the pump’s discharge outlet.

What are the advantages of a slurry pump?
Ability to Handle Abrasive Materials: Designed to withstand the erosive effects of abrasive slurries commonly found in industries such as mining, dredging, and construction.
Efficient Transfer: Utilizes centrifugal force to transport slurries over long distances and varying elevations efficiently.
Durable Construction: Constructed with robust materials and specialized coatings to resist wear and corrosion, ensuring long service life.
Versatility: Capable of handling a wide range of fluid viscosities and solids concentrations, making it suitable for diverse applications.

Is a self-priming pump good?
Yes, a self-priming pump offers several advantages, including eliminating the need for manual priming, reducing downtime, and improving operational efficiency. It is particularly beneficial in applications where priming water may not be readily available or practical.

What are priming pumps used for?
Priming pumps, including self-priming pumps, are used to remove air or gas from the suction line of a pump, creating a vacuum that allows the pump to draw fluid into the system. They are commonly used in situations where the pump is located above the fluid level or when the suction line contains air pockets that need to be evacuated.

Which is the best, self-priming or centrifugal pumps?
The choice between self-priming and centrifugal pumps depends on the specific application requirements. Self-priming pumps offer the advantage of automatic priming, making them suitable for situations where priming water is not readily available. On the other hand, centrifugal pumps are generally more efficient for high-flow, low-viscosity applications. The best pump for your needs will depend on factors such as fluid viscosity, solids content, suction conditions, and operational preferences.
