Pump Model: SHR/75C (4/3C-AHR)

At present, the lubrication methods of slurry pump bearings are grease lubrication and thin oil lubrication. The advantages and disadvantages of these two lubrication methods are explained as follows:
Grease lubrication is a lubrication method in which grease is filled in the bearings. This method was used when the WARMAN pump was introduced. This lubrication method has been verified by the market for decades and has been operating well. It has been recognized by most slurry pump users. .
Thin oil lubrication is a lubrication method where the bearing is immersed in the oil bath to lubricate the bottom of the oil bath. In addition to some slurry pumps, this lubrication method is also used for some sewage pumps and chemical pumps. It is also a very mature lubrication method in the pump industry.
Comparison of the advantages & disadvantages of the two lubrication methods

The main part of the sand gravel pump accessories is also called the overflow part. Including pump cover, impeller, volute, front guard, rear guard, etc.
This series of pumps are horizontal, single pump casing centrifugal pumps. The pump body and pump cover are clamped by special clamps, and the outlet direction of the pump can be in any position of 360 degrees, which is easy to install and use.
The shaft seals of the sand gravel pump include packing seals, impeller seals and mechanical seals.
Bearing assembly: The bearing assembly of the sand gravel pump adopts a cylindrical structure, which is convenient to adjust the gap between the impeller and the pump body, and can be removed as a whole during maintenance. Bearings are grease lubricated.
Transmission mode of sand gravel pump: there are mainly V-shaped V-belt transmission, elastic coupling transmission, gear reduction box transmission, hydraulic coupling transmission, frequency conversion drive device, thyristor speed regulation, etc.
The overall performance of the sand gravel pump: the material of the overflow parts is made of high-hardness wear-resistant alloy cast iron. The pump has a wide flow channel, good cavitation performance, high efficiency and wear resistance. Various speeds and variants are used to allow the pump to operate under design conditions. It has a long service life and high operating efficiency, and can meet many kinds of harsh conveying conditions

As the name suggests, the Slurry Pumps are for pumping materials. The key to slurry pump success is the generation of centrifugal force, which pushes material outward from the pump center.
Heavy Duty Slurry Pumps can withstand extensive wear due to characteristics such as a large impeller diameter, shafts, bearings, and internal passageways as well as heavy-duty construction. On an industrial level, slurry pump features generate higher upfront and operational costs compared to water pumps. However, only slurry pumps can hydro transport solid materials efficiently, and the long-term benefits outweigh the initial costs.


According to different usage scenarios, the slurry pump can be divided into three types:
Wet — In this installation, the slurry pump and drive are fully submersible. This is necessary for certain slurry pump applications, such as underwater operations.
Dry — In this installation, the pump drive and bearings are kept out of the slurry. The wet end — which includes the shell, impeller, hub or suction liner, and shaft sleeve or stuffing box — is free-standing and clear of any surrounding liquid. Slurry pump technicians install most horizontal pumps this way.
Semi-dry — This special arrangement is used for dredging applications with horizontal pumps. Operators flood the wet end and bearings but keep the drive dry. Bearings require special sealing arrangements in this case.

This situation is generally due to the slurry pump suction pipe, or the instrument appears the phenomenon of air leakage, or may be due to the bottom of the slurry pump valve, not open the reason caused by. When encountering this kind of failure, the technical personnel should first check where the leakage position is, and give plugging in time. Secondly, the bottom valve of the slurry pump is repaired and replaced.
