Slurry Pump Maintenance – When Should I Call the Experts

Slurry pumps, like all machines, require regular maintenance in order to work efficiently and reliably. Pumps can fail in a catastrophic failure. This can lead to unscheduled repairs, damage, and downtime. Poorly maintained pumps can reduce pump output by 15% and cause damage to the bottom line.

Pump operators and owners can do some maintenance themselves, but some situations call for professional assistance. Do not wait for your pump to fail. Contact your slurry pump's parts & service experts in order to inspect the tool and address the problems. They can better tell you the reasons why your pump is underperforming and provide you with a proper solution. 

This slurry pump maintenance guide can be customized to meet your needs. Then, follow the steps to keep your pumps in peak condition.

Daily maintenance

Although this maintenance list may seem long, the individual items are quick and simple to complete. These daily steps, even though they seem small, are crucial to maintaining pump efficiency.

  • You should only check the oil when it isn't in use.
  • If there are sudden temperature drops or spikes, inspect the bearings.
  • Take a look at the stuffing box, and make any necessary adjustments.
  • Consistently monitor all gauges.
  • Check for leakage. If the weep holes in the pump casing are leaking, replace the liners.
  • Monitor the gland service pressure. Any changes could indicate more problems. A blocked pipe or a badly functioning stuffing container could cause a drop in gland service pressure.
  • If the V-belt was installed within the last few days, make sure to check the drive. New V-belts are stretched and require re-tensioning as soon as possible.

Weekly maintenance

Weekly maintenance is important! These two tasks are not only necessary for your weekly maintenance, but they are vital to track and ensure pump efficiency.

  • As needed, adjust the impeller.
  • Take gauge readings.

Quarterly maintenance

Quarterly tasks require more hands-on duties and can require the attention and skill of an on-staff mechanic. However, they could make the difference between a functioning pump and a catastrophic failure.

  • Empty used lubricant and replace with fresh oil.
  • Check the V-belt for signs of wear and to ensure proper tension. Clean the V-belt and pulley grooves.
  • Clean and oil studs and threads on the motor base and gland.
  • Inspect the stuffing box for wear and re-pack.

Semiannual maintenance

Last but not least, semiannual maintenance tasks should be performed because they do more than just inspecting the parts of the pump.

  • Inspect the whole pump.
  • Clean bearings and housings, then add fresh oil.
  • Check and flush the drains, as well as seal the water piping.
  • Make sure the motor and pump are properly aligned.

It is essential to keep accurate records throughout all maintenance phases. If you have multiple employees who record gauge and instrument readings at your facility, make sure they use the same process each time. This will ensure that records are easy to compare and read.
