Mini Grout Pump
Safe Working Regulations for Pumps of Mini Grout Pump:
1. During lifting of grouting pump, attention must be paid to
prevent overturning accidents, and the wire rope should be firmly
tied to the four corners of the base.
2. After the grouting pump and pump pipeline are installed, apply
water under working pressure before starting to use, and check
whether the installation quality and pressure safety device can
work normally.
3. All wires connected to the grouting pump shall be overhead or
loaded with rubber hose.
4. Grouting pump has no grounding wire, so it is absolutely
forbidden to use it.
5. It is forbidden to continue working when there is any damage
trace outside the grouting pump.

Structure of Mini Grout Pump:
Mini Grout Pump is mainly composed of pump body, pump frame, air chamber, shock-resistant pressure gauge, motor, V-belt and pulley cover.
The installation foundation of cement grouting pump should be
smooth and not inclined.
The pump is fixed on the foundation with the foot screw to prevent
the vibration of the pump during operation.
Preparations before pumping of Mini 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.
