Check whether pump fasteners are loosen and whether the pump body runner is blocked by foreign matters before installation to avoid damage of impeller and pump body in running.
Supporters for the outlet pipe should be installed separately so that the weight will not be added to the pump so as to prevent it from deformation. The pump base for both movable and fixed installation must be leveled by a level. After the base is ready, install the pump on the base and then use a level to check horizontal and vertical situation between the pump and motor shaft. Use the iron shim to change the height of the base if the pump is out of level. Then grout the base and anchor bolt holes by pouring the concrete into the grout hole.
The levelness of the coupling device should be calibrated by a level when coupling installation is adopted. Horizontal level tolerance should not exceed 0.1mm/m. Use the measure gage to calibrate parallelism of two coupling rods to ensure the parallelism tolerance will not exceed 0.2mm/m.
Tighten the anchor bolt to make sure there is no looseness between the anchor bolt and concrete in case of bad influence on pump performance when starting.
For easy maintenance and safe use, install a regulating valve on the outlet pipe and a pressure gauge
near the outlet to guarantee the normal operation within the rated performance range, which lengthens the lifetime of pumps.
Rotate the impeller from the suction side after installation. Disassemble the pump and find out the reasons if there is friction or stuck pump.
The pump installation can be divided into three types, movable type, fixed type and coupling type.
