The core of correctly installing a slurry pump is to ensure that the equipment model matches, the foundation is stable, the alignment is precise, the sealing is reliable, and to strictly follow the operating specifications to avoid problems such as cavitation, vibration, and leakage.
Slurry pumps are widely used in industries such as mining, metallurgy, power, and environmental protection to transport abrasive slurries containing solid particles. Due to its harsh working environment, improper installation can easily lead to bearing damage, mechanical seal failure, and increased vibration, seriously affecting its service life and operational efficiency. Therefore, a scientifically standardized installation process is crucial.
According to multiple technical documents, although the slurry pump has been tested before leaving the factory, it still needs to be installed correctly on site to ensure performance. Installation mainly includes the layout of units with horizontal or vertical structures, pipeline connections, motor alignment, shaft seal configuration, and other aspects.
Installation steps and key points (organized according to the process)
The following are the main steps and corresponding technical points for installing slurry pumps:
Pre-installation check
Check the packing list, confirm that the equipment model, parameters, and components are complete, and that the accompanying technical documents are complete.
Read the "User Manual" and other materials in detail, master the operating essentials, and avoid blind construction.
Foundation and location preparation
The installation foundation should be solid, flat, and have sufficient bearing capacity to prevent vibration during operation.
The horizontal pump is fixed using secondary grouting method to ensure that the centerline of the unit is consistent with the foundation, with a deviation of no more than ± 2mm.
Installation of pump body and motor
Lift the pump body to the base and fix it, paying attention to the direction and horizontal reference.
When installing the motor, soft cushions should not be used, and it should be directly fixed on a rigid foundation, with evenly tightened anchor bolts.
Alignment of transmission device
Couplet direct connection unit: use a knife edge ruler+plug gauge or magnetic dial gauge to align, with outer circle runout ≤ 0.15mm and end face clearance error ≤ 0.10mm.
For belt drive units: Use a ruler or cable to correct the parallelism of the pulley end face.
pipeline connection
The suction pipe diameter should be equal to or slightly larger than the pump inlet diameter to avoid cavitation and sedimentation.
Valves should be installed on the outlet pipeline to regulate the flow rate, and throttling on the suction side is strictly prohibited.
Install expansion joints between the pump and the pipeline for easy disassembly and maintenance.
Shaft seal and lubrication system configuration
Mechanical seal pumps must ensure the supply of shaft seal water, and it is strictly prohibited to operate without water, otherwise the seal will be burned.
Before starting the thin oil lubrication pump, it is necessary to add oil to the specified position according to the oil gauge, and it is strictly prohibited to operate without oil.
Electrical and trial operation
The wiring is completed by a professional electrician to ensure grounding safety.
Before testing, check whether the steering is consistent with the bracket arrow, and prohibit reverse turning to drive the pump shaft.
Observe whether there is any abnormal noise, leakage, or overheating during the no-load trial operation.
Conclusion
The long-term stable operation of slurry pumps depends on whether the "three stricts" are implemented during the installation phase: strict inspection of equipment, strict control of alignment, and strict sealing. Any negligence can lead to early failure. It is recommended that experienced technicians follow the manufacturer's manual and keep a record of the trial operation.
