The bearing and service life of the slurry pump are the most concerned issues for users.

The bearing and service life of the slurry pump are the most concerned issues for users.


 First of all, from our company's varieties of slurry pumps, our company has heavy-duty slurry pumps, light slurry pumps, and subprime slurry pumps. Mainly include: MAH, M, MHH series, L series, MSP submerged slurry pump series, various types of slurry pumps can use different speeds and different variants, the same type of pump with multiple flow, lift, structure . At the same time, in order to meet the requirements of different working conditions, the pump flow parts can have different materials, including hard nickel, Cr27, Cr15Mo3, high chromium 8# and so on.

Characteristics of Chifeng slurry pump produced by Mizztech

 Slurry pump The pump body cover and over-current components are divided into horizontal and vertical medium-sized, double-pump shell structure slurry pumps. The pump body and pump cover are equipped with a replaceable metal lining. The lining is made of high-chromium wear-resistant alloy material. The lining can be used until wear-through, which extends the maintenance period and reduces operating costs. The pump outlet direction can be rotated and installed at 8 angles.

 Bearing assembly: The bearing assembly of the pump adopts a cylindrical structure, which is convenient for adjusting the clearance between the impeller and the front guard plate, and can be completely removed during maintenance. The bearings are greased.

Shaft seal (seal): The shaft seal type of the pump has packing seal, impeller seal, mechanical seal

In order to reduce your maintenance costs and extend the life of the slurry pump, our company will introduce the following points for you:

1 The pump should be replaced with the butter in the motor support oil cup after the first month of operation or after 100 hours of operation, and then replaced after 2000 hours of operation.

2, pay attention to the pump bearing temperature, should not exceed the external temperature of 35 degrees but the maximum should not be greater than 75 degrees.

3. Regularly check the flexible coupling and pay attention to the temperature rise of the motor bearing.

4, the oil cup should be filled with calcium-based butter to ensure that the bearing can be properly lubricated.

5, the pump should be cycled every 2000 hours of operation, the friction between the impeller and the pump body (or pump cover) should not be too large, the maximum value of the gap should not exceed 1.5 mm, such as more than replaceable impeller or front cover.

6. When the pump is working for 6 hours, the machine seal should be inspected and repaired or replaced according to the degree of wear, otherwise the pump shaft and bearing will be damaged.

7. During the process of moving, if noise or unusual sound is found, stop immediately and check.
