So many of us get caught up tackling many different tasks when it comes to caring for or maintaining our slurry pump, it can be easy to overlook pumps in any routine maintenance program. If a slurry pump is not maintained or regularly inspected, it can go down without warning or lose efficiency over time, causing downtime and reduced productivity. This can have a major impact on any process’s bottom line and eventually cost more money to solve in the end!Here is some aspects that need to paid attention to when using the slurry pump.

Starting up

·   Before starting please check the pump by the order listed below.
·  The pump should be placed at a secure base which can stand the weight of the pump and minimize vibration. Screw all the foundation bolts tight.
·  The pipe and the valve should have separate supports.
·  Use hands to turn the shaft to the direction of the rotation of the pump. The shaft should be able to drive the impeller and there should be no friction, otherwise the gap between impeller and frame plate liner and the gap between the impeller and the throat bush should be adjusted.
·  Check the direction of rotation of electric motor. Make sure the pump turn in the direction as labeled on the frame plate. Note that the pump must not turn in the reverse direction. Otherwise the impeller may be screwed off the shaft and damage the pump.
·  If coupling is used, the shaft of the pump should be exactly co-centric with the shaft of the electric motor. For V-belt drive, the pump shaft and the motor shaft should be parallel. Adjust the position of the groove such that it is perpendicular to the belt,so as to avoid violent vibration and wear and tear.

Operation

·   When the machine is in operation, check the pressure and volume flow rate of the sealing water regularly, if sealing water is used. Adjust the tightness of sealing cover and replace the stuffing if necessary. Ensure that there is always enough clean water passing over the shaft.
·  Check the bearing assembly regularly. If the bearing gets overheated when the operation is started, the pump should be switched off to let the bearing cool down, and then switch on the pump again. When the bearing still gets severely overheated and the temperature keeps rising, the bearing assembly should be stripped and carefullyexamined to find out the reason. Usually the overheating is caused by excessive lubricant or impure lubricant. The lubrication should be clean and of an appropriate amount. Lubricants should be added regularly.
·  The efficiency of the pump decreases as the gap between the impeller and throatbush increases. Thus the impeller should be moved forward regularly to ensure the gap is kept at an appropriate size. When the parts are worn such that the system requirement cannot be met, the wearing parts should be replaced.

Shutting down

·  Before shutting down the pump, if possible, the pump should be allowed to transport clean water for a while so as to clean the slurry inside the pump.

·  Then the pump,valve, and sealing water should be stopped in turn.
