Preparations before pumping of Maonry Grout Pump:
After the pump has been stopped or reinstalled for a long time, the following preparations must be made before starting.
1. Check whether there is enough lubricating oil in each part.
2. Check whether the suction pipe of the filter is unblocked.
3. Check whether there is obstruction in the movement of each part.
4. Check the accuracy and reliability of the transmission mechanism.
5. Check the looseness of fasteners, especially the screw tightening of rubber piston locking nut, cross head and piston rod connection thread.
6. Check the suction height of the pump. The maximum suction height of the pump should not exceed 2.5 meters in areas below 1000 meters above sea level. In areas above 1000 meters above sea level, the suction height of the pump should be reduced according to the local atmospheric pressure reduction.
7.Check the position of the filter immersed in the mud tank. Generally, the mud level should be below 0.3-0.5 meters, and the filter should be no less than 0.5 meters away from the bottom of the mud tank.
