A dredge pump contains a pump casing and an impeller. The impeller is mounted in the pump casing and connected to the drive motor via a gearbox and shaft. The front part of the pump casing is sealed with a suction cover and connected directly to the suction pipe of the dredger. The discharge port of the dredge pump is located near the top of the dredge pump and is connected to a separate discharge line.

Read MoreWhen 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.

- 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.
- Slurry pump construction materials
- - By increasing the size of the worm housing, the speed at which the media moves is reduced. This lower velocity translates into lower wear.
- 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.
- Slurry Pump
- Some models can generate discharge pressures up to 260 ft. (80 m).

A wide range of sealing devices are used in various machines.
Sealing devices serve the following functions:Why use NOK-CN factory-made oil seals?
- Another important function of the oil seal 29x44x7 is to reduce friction and wear between the rotating shaft and the housing
oil seal 29x44x7. As the shaft rotates, the seal provides a cushioning effect and reduces the amount of contact between the two surfaces. This not only extends the life of the shaft and housing but also improves the overall efficiency of the machine by reducing energy losses due to friction.
- Press the retaining ring onto the shaft with an even movement.
- 8. Fill the engine with fresh coolant and start the engine to check for leaks.
4) Allowable total eccentricity
- - Torque the valve cover to the manufacturer's specifications to maintain the correct seal.
2. Oil seal structure and functions
ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
Usually, these oil seals are used to seal lubricating oil or grease and contain it within the application, so that moving parts such as bearings are continually supplied with enough lubrication. However, such seals are also used for sealing other liquids, gases, and solids, such as powders or granules.
Shaft Speed
Types Of Oil Additives
Oil seals are available in an immense range of sizes, for shafts from a few millimetres to several metres. Once the shaft diameter, groove diameter (housing diameter) and groove width are known, selecting an appropriate oil seal is a simple task. An oil seal or its product description is usually associated with three dimensions, for example 6x15x4. These refer to the sizes of the hardware for which the oil seal is designed. In this example, this oil seal is suitable for: 6-mm shaft diameter x 15-mm groove diameter x 4-mm minimum groove width.
There are a wide range of oil seals to select from for any number of uses, so this guide will break down the most common seals to help you choose the right one for whatever piece of machinery you are working on.
1) Common seal types and their features


Oil seal performance is affected by not only the type and material of the selected oil seal, but also a variety of other factors, such as operating conditions, total eccentricity, rotational speed, the substance to be sealed, and lubrication conditions.
