Shear pump is a auxiliary equipment in solid control system. It is used to effectively mix and hydrate material added into drilling fluid. With large capacity, high lift, and long reliable service life, the shear pump can speed up dilution and hydration of polymers to have high property mud.

There are several parts in shear pump, including impeller, volute, packing case, shaft, combination belt and other machines. So how to efficiency and right use and maintain the shear pumps ? Below is the maintenance methods of shear pumps.


1)Clean the pumps and pipelines with clean water to avoid blocking impeller channel and nozzles
2)The first operation or operate shearing pump after long time we need to lubricate seal case and bearing case
3)Before running shearing pump we must open the inlet and output gate
4)Feed 10~20ml lubrication grease in bearing case every week. Feed 10~20ml lubrication grease in seal case very week
5)Adjust seal case cover every week if we can’t adjust it anymore then we need to replace two packings. 2 ends of new packing request 45┬░degree. Make sure packings touch each other tight on the bearings when install them every 2 packings should be 90-150┬░ degree direction
6)In cold seasons if pump will be stopped long line please screw out the nut under pump case release drilling fluid to avoid freezing.

DC Machinery research large number of domestic and foreign shear pump based on the improvement of shearing pump, comprising a complete shear and hydration system, quick shear dilution, a hydratable polymer.
