The main objective of all flush water programmes is to prevent contamination of the seals by pumped water.The flush water programme for boxes is therefore very similar to the flush water programme for mechanically sealed boxes. However there are still some obvious mechanical differences. The most notable difference is the addition of a seal (packing) between the inlet and outlet limits. This minimises the amount of flushing fluid consumed.

Cavitation can occur due to surges; a very effective way to solve this problem is to install a choke on the pump head to increase the pressure on the casing, which then absorbs the surge, or to add a choke to the output to reduce the surge.

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 MoreWhen dealing with slurry, you generally want to go bigger and slower. The thicker the impeller, the better it will hold up. The slower the pump, the less erosion will inflict on the impeller. However, the impeller isn’t the only thing to worry in slurry pump when dealing with slurry. Tough, durable materials of construction are necessary most of the time. Metal slurry pump liners and wear plates are common in slurry applications.

- Despite the complexity of internal flow patterns, the overall performance of dredge pumps is predictable.
- 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.
- 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.

1. The two types of pumps are all centrifugal pumps in the working principle. They are machines that increase the energy of solid and liquid mixtures by means of centrifugal force (the rotation of the impeller of the pump).

- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.
- 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.
- Compared to standard centrifugal pumps, centrifugal pumps optimized for slurry pumping typically have the following features.
- The selection of a dredge or , slurry pump, can be a challenging process that can be simplified by understanding the main factors behind the smooth operation of a pump. In addition to providing more efficient performance, the right dredge pump requires less maintenance, lower power and a relatively longer life.

- In harsh conditions with sand, sludge, rocks and mud, ordinary slurry pumps tend to clog, wear and fail frequently. But WA heavy duty slurry pumps are highly resistant to wear and corrosion, which means that the service life of our slurry pumps is better than other manufacturers' pumps.
- - Smaller, more efficient tank - Because the motor is cooled by the surrounding liquid, the submersible slurry pump can be started up to 30 times per hour, resulting in a smaller, more efficient tank.

- There are three different >types of slurry pump impellers; open, closed, and semi-open. Each has its own strengths and weaknesses, depending on the application. Some are better for solids handling, others are better for high efficiency.
- A clear clean fluid supplied from an external source is normally used which is delivered to the main sealing surface on the fluid side of the sealing process. By using a closed gap throat bushing, the stuffing box can be back-pressurised to a higher pressure, ensuring that the flushing fluid does not flash across the seal face.
- Definition of dredge and slurry pumps
- 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.

- Submersible Slurry Pump
- The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications. There are many drive modes for option, such as V-belt, flexible coupling, gearbox, hydraulic coupler variable frequency, silicon controlled speed, etc. Among them, the flexible shaft coupling drive and V-belt feature of low cost and easy installation.
- 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.
