Read MoreMixers can also help agitators when pumping very dense particles. In applications where the tank is small and/or where pumping is desired to lower the water level in the tank, a slurry pump with an internal cooling system should be considered to avoid overheating of the stator (when the water level gets low). When pumping sediment from a dam or lagoon, consider the use of a raft unit, which is a submersible device. Agitators are recommended, as well as one or more mixers that can be mounted on the raft or pump to resuspend particles for successful pumping of particles.

Read MoreThe size of slurry pump impeller must be considered to ensure it holds up against abrasive wear. Slurry pump impellers are generally larger in size when compared to slurry pumps for less abrasive liquids. The more “meat” the impeller has, the better it will hold up to the task of pumping harsh slurry mixtures. Just think of slurry pump impeller as a football team’s offensive line. These players are usually large and slow. Throughout the whole game they are beaten up, over and over again, but expected to withstand the abuse. You wouldn’t want small players in this position, just like you wouldn’t want a small impeller on your slurry pumps.

- It is critical to determine the right slurry pump size and power requirements for your application. Depending on the abrasive nature of the slurry, it is important to select a pump size that will allow it to run at a slow enough speed to extend the life of the slurry pump. The ideal RPM to run a slurry pump is between 900 and 1200 RPM. Once that speed is started to be exceeded, the life of the pump is greatly reduced because the wear points of the slurry pump are actually sandblasted.

- Depending on the abrasive nature of the slurry, it is important to select the ideal seal. Slurry pump seals should have a hardened surface made of silicon carbide or tungsten carbide. Vortex pumps use patented seal technology that utilizes a double mechanical seal setup and a separate seal flushing system. This allows the sealing surface to be kept cool at all times without causing the slurry to overheat the seal and crack the surface.
- The concept of the >slurry pump and mud pump is very close, many people are not quite clear. Although slurry pumps and mud pumps are impurities pump, if you fully understand the two pumps, you can differentiate them very clearly from the application and transmission medium characteristics. What is the difference between the slurry pump and mud pump? Four aspects to distinguish the slurry and mud pumps.
- A quench plan, as the name indicates, is designed to quench or cool the seal. It is normally used if short periods of dry running are expected. As illustrated bellow, the fluid is introduced into the area between the back of the seal faces and the close fit exit on the drive side of the pump.
- Fewer and thicker vanes on the impeller. This makes it easier for solids to pass through than the 5-9 vanes on a standard centrifugal pump - usually 2-5 vanes.

- Slurry Pump
- Pumping slurry can cause excessive wear and tear on the pump and its components as the mud can clog the suction and discharge lines.
- Critical to the engineering of the pump are heavy duty bearing frames and shafts, extra thick wall sections and easily replaceable wear parts. Total life cycle cost considerations are critical when specifying pumps for severe operating conditions, such as FGD service. High chrome pumps are ideal due to the corrosive pH of the slurry.
- Corrosiveness of the liquid or slurry mixture: More corrosive slurries will wear pump components faster and may dictate the choice of pump manufacturing materials.
- Submersible pumps offer many advantages over dry installation or even semi-submersible sump pumps. Submersible pumps are more flexible and efficient than alternatives.
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- Process speed doesn’t have anything to do with choosing slurry pump impeller, but it does have an effect on the life of slurry pump impeller. It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.
- - Lower operating costs - Typically, submersible slurry pumps require much lower operating costs than dry mounted pumps due to higher efficiency.
- -When pumping abrasive slurries, it is essential to use wear-resistant components with a high chromium content. But more is not always better - above 25%, the impeller becomes brittle.
- Settling slurries are formed by coarse particles, which tend to form unstable mixtures. Special attention should be paid to flow and power calculations when selecting a pump. Most slurry applications consist of coarse particles and therefore have a higher abrasion resistance.
