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.

Read MoreWith 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.

- Portable and low maintenance - There are no long or exposed mechanical shafts between the motor and worm gear, which makes the submersible pump more portable. In addition, because there are no long or exposed mechanical connections between the motor and worm gear, less maintenance is required and operating costs are significantly lower.

How to Choose a Dredging Pump or Slurry Pump
-
Choosing the right pump for your slurry is critical to getting the most out of it. Basic pump components such as impeller size and design, materials of construction and discharge configuration must be considered to ensure that the pump can withstand the wear caused by abrasive slurries. Compared to low-viscosity liquid pumps, target=_blank title=Slurry Pump>slurry pumps are typically larger and often require more horsepower to operate because they are less efficient. Bearings and shafts must also be more robust and durable.

- >Slurry pumps are typically larger than standard pumps, with more horsepower and stronger bearings and shafts. The most common type of slurry pump is the centrifugal pump. These pumps use a rotating impeller to move the slurry, similar to the way aqueous liquids move through a standard centrifugal pump.

- Ideal for slurry pumps - Only rubber lined pumps combine strength and corrosion resistance to create a quality slurry pump.
- 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.

- >Dredge pumps are a special category of pumps used in the dredging process. Dredging is the process of transporting submerged sediments (usually sand, gravel or rock) from one area to another. Dredging takes place in the shallow waters of lakes, rivers or seas for land reclamation, dredging, flood control, new harbours or expansion of existing harbours. The various industries that use dredge pumps are therefore the construction industry, mining, the coal industry and the oil and gas industry.
- Consider the following.
- Improved flow control
- - 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.
- Choosing the right material for a slurry pump is another key process in determining the right pump for handling slurry. If the slurry is highly abrasive with neutral pH, then the best material of construction is Hi-Chrome. this metallurgy has the highest Brinell hardness and can withstand the abrasiveness of the slurry.

- 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.
- If you have experience pumping slurries, you know it's not an easy task. Slurries are heavy and difficult to pump. They cause excessive wear on pumps and their components and are known to clog suction and discharge lines if not moving fast enough. Most importantly, it’s a challenge to make slurry pumps last for a reasonable amount of time. But, there are a few things you can do to extend the life of your slurry pump and make pumping slurry less of a challenge.

- Horizontal pumps are the most commonly used type of slurry pump and therefore have the advantage of being easy to install or maintain, a wide range of flow parameters to choose from and a wide range of design materials to choose from. One of the advantages of vertical pumps, however, is the relatively small amount of floor space required for installation.

- Other manufacturers looking for differentiation, if not the end result, may choose to add a small part to their pump assembly in the description, thus allowing in-line adjustment of the wear ring in the suction side lining assembly.
- 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.
- Fine-grained sand can be extremely abrasive and typically wears slurry pumps quickly. Characteristics of coarse aggregates that can affect pump performance are size, shape and surface texture, as well as gradual changes in particle size, while fine materials can create excessive friction in the pipe.
- Some models can generate discharge pressures up to 260 ft. (80 m).
- Caution: A common mistake is to over-pressurise the box and damage the expensive mechanical seal.

- Slurry Pump
- 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.
- 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.
- 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
- Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.
- Slurry pump design
- 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.
- Pumps designed to pump slurries will be heavier than pumps designed for less viscous liquids because slurries are heavy and difficult to pump.
- It is important that the pump you choose has components that will not wear out from abrasive slurries.
