When using a submersible slurry pump for dry installation, the slurry pump must always have a cooling system installed. Consider the design of the water tank in order to deliver slurry to the pump. Agitators and side-mounted agitators cannot be used for this type of installation.

Read MoreIf you have experience pumping slurry, you know it is not an easy task. Slurries are heavy and difficult to pump. They can cause excessive wear on the pump and its components, and if they don't move fast enough, they can clog the suction and discharge lines. Most importantly, it can be a challenge to keep a slurry pump in use for a reasonable period of time. However, there are steps you can take to extend the life of your slurry pump and reduce the challenges of pumping slurry.

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.

The size and nature of the solids in the liquid: The size and nature will affect the amount of physical wear on the pump and its components, and whether the solids will pass through the pump without being damaged.

- Any type of impeller can be used in slurry applications, but closed slurry pump impellers are more common because they are high efficient and abrasion Resistance,. Open slurry pump impellers are usually used well for high concentration solids as they are less likely to clog. For example, the small fibers in paper stock which, in high densities, may have a tendency to clog the impeller. Pumping slurry can be difficult.

- Another important target=_blank title=Part of the Slurry Pump>part of the slurry pump is its casing, which bears all the pressure. The slurry pump casing should have a large clearance between the impeller and the diversion angle to reduce wear and prevent large solid particles from getting stuck. Due to the extra space, there is more recirculation in the slurry pump casing under various operating conditions. Again, this accelerates wear compared to typical pumps.
- The Mud pumps need to be equipped with auxiliary equipment, but slurry pumps not. They often need to use with high-pressure water pump when mud pump working. The high-pressure pump sent the water that larger than the mud pump pressure to the leakproof packing. Then protect the packing. Otherwise, it is easy to make the seal part wear. But the wear-resistant slurry pumps can complete the transportation work independently, which not need to equip other auxiliary equipment.
- A >dredge pump is a horizontal centrifugal pump that is the heart of a dredger. It is designed to handle suspended abrasive granular materials and solids of limited size. Without a dredge pump, a stranded dredger would not be able to deliver mud.

- Keep in mind that slurry pumps are designed to adapt to specific pumping conditions. Pumps used in the cement industry handle most fine particles at low pressures, so the casing can be of lightweight construction. In rock pumping, the casing and impeller must be able to resist slamming, so they must be built thick and strong.
- 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.

- Compared to standard centrifugal pumps, centrifugal pumps optimized for slurry pumping typically have the following features.
- First, what is a slurry? A slurry is a semi-liquid mixture, usually consisting of fine particles. Examples of slurries can include manure, cement, starch, or coal suspended in water. There are countless other combinations that can be considered slurries. Because of the added particles and thicker consistency, special pump requirements should be considered. A standard pump may be able to handle the fluid, but not as effectively as a properly sized slurry pump.
- In a subsea installation, the slurry pump runs directly in the slurry and does not require a support structure, which means it is flexible and easy to install. If possible, the catch basin should be equipped with sloping walls to allow sediment to slide down into the area directly below the pump inlet. Agitators should be used when the liquid contains large amounts of solids and has a high particle density. Freestanding or side-mounted (submersible) mixers are an excellent choice for resuspended solids, especially if the catch basin is large or does not have sloping walls.
- The impeller is considered the heart of the dredge pump and is similar to a fan that expels air and creates centrifugal suction. At the suction pipe, this vacuum absorbs the slurry and transports the material through the discharge line.
- Typically, slurries are.
- It is important that the pump you choose has components that will not wear out from abrasive slurries.
- The 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.
- 1.Find the spot that allows the pump to run as slow as possible (to reduce wear), but fast enough to keep solids from settling and clogging the lines.To reduce wear, lower the pump’s discharge pressure to the lowest point possible. Follow proper piping principles to ensure a constant and uniform delivery of the slurry to the pump.
- Determine the size of the pump
- The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.

- As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.
- There is a science behind the design of a , slurry pump, , based primarily on the processes and tasks it will perform. This is why it is important to use the right slurry pump for your specific needs. In a field that encompasses so many specialities, long-lasting, efficient and reliable quality equipment is essential.
- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- How does a dredge pump work?
- The length of the piping. The longer the pipe, the more slurry-induced friction the pump needs to overcome.
- 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.
- - By increasing the size of the worm housing, the speed at which the media moves is reduced. This lower velocity translates into lower wear.
- The same point of slurry pump and mud pump
- The rule of thumb for setting the water pressure is the same when using the pack box, whether flushing. Mud pump shut-off pressure plus 10% or plus 20 psi, whichever is greater. However, the flow rate is set differently.
- Choosing Dry Slurry Pumps Versus Submersible Slurry Pumps
- On the other hand, if the slurry is not only abrasive but also has a low pH, then a duplex stainless steel construction is preferable. This material is best suited for slurry pumps to withstand harsh materials (such as acids) while still having a high Brinell hardness.
