Sanitary Pumps, Value the Checks and Observations, Preventing Costly Downtime

Sanitary pumps are a crucial equipment piece for brewery process. It is considered crucial as if a pump shuts down; the entire operation comes to a halt. Thus, it means pump maintenance should be implemented with regular check so that the sanitary pumps stay in optimal condition.

Here are few checks that must be done and to begin with are:

Daily inspections

Sanitary pumps inspections must be done daily and there is a need to record the irregularities, if any. Even changes in the sound of the pump, seal chamber leakage or any change in the temperature. Also take a note of the pressure gauge readings, vibration observations and flow meter monitoring as a daily check.

Also create trending charts for the pumps that have recording instruments monitoring the capacity, power consumption and pressure. Daily inspections helps as you can know the specific performance value deterioration and on identifying can consider appropriate maintenance works.

Leaks

Look for excessive or new leaks, particularly, the dripping oil from gaskets. Check the seal chamber, pump casing and piping.

Temperatures, cooling and heating

The temperature of the pump must be regularly monitored so that you ensure the pump is running at its optimal temperature. In fact, even the fluid type will determine ideal temperature. Conversely, it should not excessively fluctuate on daily basis.

Noises

Listen for any disturbing or unusual sounds. In case you hear to some bearing noise, make sure it is not louder than the normal noise and so lubricate the bearings.

Oil

Check regularly the oil and also the oil levels. If you observe it to be watery or appear to have an odd color, get it changed.

Performance parameters

Monitoring the suction pressure and discharge for extreme movement is essential. Check the flow rate, power, efficiency and speed of the pump. Also track if there is a potential problem and consider options early so that you avert the damage to the pump and thus prevent costly downtime. Some of the procedures can be considered as quarterly checking tasks such as:

Oil change.
Ensure the hold-down bolts and foundations are tight.
Inspect the alignment of pump shaft and realign as required.
Even if your pump is idle, check and replace the mechanical seal, if required.

Annual inspections may fulfil these three parameters such as the pump pressure, pump capacity and pump power. If the performance of the pump seems to be unsatisfactory, firstly, disassemble the pump, inspect and replace the worn parts.
