It's important to work with a qualified engineer when selecting a slurry pump, because slurry can wreak havoc on a pump if not selected properly.

- Pumping slurry can present some challenges and problems, but with proper engineering and equipment selection, you can experience years of trouble-free operation. It's important to work with a qualified engineer when selecting a slurry pump, because slurry can wreak havoc on a pump if not selected properly.
- Centrifugal slurry pumps capable of providing high capacity with a limited head are mainly used for pumping slurry through pipes with a concentration of less than 70% by weight of solids. Centrifugal slurry pumps can be vertical, horizontal or submersible.
- 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.
- Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.
- Mechanical Seals
- 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.
- Dredge Pump Features
- - By increasing the size of the worm housing, the speed at which the media moves is reduced. This lower velocity translates into lower wear.
- 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 - typically 2-5 vanes.
- When the slurry pump working, pump parts are easy to be impacted, wear, and corrosion, etc. Therefore, the liner of the slurry pump uses wear-resistant material, such as high chromium alloy, rubber. The wear-resistant materials can effectively reduce the wear parts of the pump. So most of the slurry pump is a wear-resistant slurry pump in the current market.
- Submersible Slurry Pump
- How much solids damage can the customer tolerate?
- Slurries are divided into two main categories: non-settling or settling. Non-settling slurries consist of very fine particles, giving the illusion of increased apparent viscosity. These slurries usually have low wear characteristics, but require very careful consideration when selecting the right pump, as they behave differently from ordinary liquids.
- A , slurry pump, is a special type of pump capable of handling slurry. Unlike water pumps, slurry pumps are prone to wear and tear and are more robust and durable.
- The winch dredger is usually equipped with a hull-mounted dredge pump, which has an impeller centered at or below the draft line for further production and improved suction efficiency.
- When pumping slurry in wet sand applications, we must evaluate the abrasive particles flowing through the piping and then assess how they affect the slurry pump. If the pump is lined with poor quality rubber, the particles will not rebound effectively and, as a result, the rubber will begin to break down. The air shavings then begin to accelerate and negatively impact the efficiency of the pump, often leading to turbulence.
- reduce the discharge pressure of the pump to the lowest possible point, and.
- 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.
- In AIER® slurry pumps, WY & WYJ sump pump are vertical centrifugal slurry pump, submerged for transfer abrasive, coarse particles and high density slurry. When working, it needs no seal water or any kind of seal. It can work well as well when suction volume is not enough.
- Natural rubber is an excellent wear material when handling wet sand slurries. Its strength, resilience and cut resistance have a positive impact on the wear performance of slurry pumps.

- Longer maintenance intervals
- With the standard flush schedule, the flow is usually adjusted by compressing the packings until a few drops of water are observed leaking from the seals on the drive side. In a quench schedule the flow rate is set by adjusting the inlet valve, while a valve is used on the exhaust side to maintain the correct seal tank pressure. If the outlet water from the seal box is too hot, the flow rate is increased until the outlet water cools, while still maintaining the correct seal box pressure.
- Especially when the dredging depth reaches 20m or more, the above situation will be more obvious. The use of underwater pumps can effectively improve the above situation. The lower the installation position of underwater pumps, the smaller the suction resistance and vacuum, which can obviously reduce the losses during the work and improve the working efficiency. The installation of underwater pump can effectively increase the dredging depth and improve the ability to transport sediment.

- The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.
- Flushing is defined as a fluid which is introduced into the seal cavity on the process fluid side, close to the seal face, and is normally used to cool and lubricate the seal face.
- The terms flushing and quench, often seem to be confused or misused when discussing seal support schemes for , slurry pumps, . As the concepts of a mechanical seal cartridge and a filled seal cartridge are slightly different, I will discuss them separately and in turn.

- In dry installation, the hydraulic end and drive unit are located outside the oil sump. 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.
- The most important thing here is to determine the pump power required to deliver a specific fluid flow at the desired or required differential pressure. Consider the following.
- Types of slurry pumps
- Although the focus of slurry pumps is often on the size and percentage of solids to be pumped, in many applications corrosion resistance is also an important factor in material selection. In such cases, the material chosen must provide adequate resistance to erosion and corrosion.
- What is a dredging pump?
- Slurry pumps with rubber lining are the ideal pump for the mineral sand industry. They have a special rubber lining that makes them heavy duty pumps capable of withstanding high levels of abrasion.
