When things are going well, it's easy to overlook routine maintenance and rationalize that it's not worth the time to regularly inspect and replace parts. But the reality is that most plants are equipped with multiple pumps to perform a variety of functions that are integral to running a successful plant. If one pump fails, it can bring the entire plant to a halt.

Pumps are like gears in a wheel, whether they are used in manufacturing processes, HVAC or water treatment, they keep factories running efficiently. To ensure proper operation of the pump, a regular maintenance schedule should be implemented and adhered to.

1.Determine Maintenance Frequency

Consult the original manufacturer's guidelines and consider scheduling repairs. Do lines or pumps need to be shut down? Choose a time for system shutdown and use common sense to plan maintenance schedules and frequency.

2.Observation is Key

Understand the system and choose a spot to observe thedouble suction pumpwhile it is still running. Document leaks, unusual sounds, vibrations, and unusual odors.

3.Safety First

Before performing maintenance and/or system inspections, ensure that the machine is shut down properly. Proper isolation is important for both electrical and hydraulic systems. Perform mechanical inspections

3-1. Check whether the installation point is safe;

3-2. Check the mechanical seal and packing;

3-3. Check the double suction pump flange for leaks;

3-4. Check the connector;

3-5. Check and clean the filter.

4.Lubricating

Lubricate motor and pump bearings according to manufacturer's guidelines. Remember not to over-lubricate. A lot of bearing damage is caused by over-lubrication rather than under-lubrication. If the bearing has a vent cap, remove the cap and run the double suction pump for 30 minutes to drain excess grease from the bearing before reinstalling the cap.

5.Electrical/Motor Inspection

5-1. Check whether all terminals are tight;

5-2. Check motor vents and windings for dust/dirt accumulation and clean according to manufacturer’s guidelines;

5-3. Check the starting/electrical equipment for arcing, overheating, etc.;

5-4. Use a megohmmeter on the windings to check for insulation faults.

Replace damaged seals and hoses

If any hoses, seals or O-rings become worn or damaged, replace them immediately. Using temporary rubber assembly lube ensures a tight fit and prevents leakage or slippage.

There are many lubricants on the market, including good old fashioned soap and water, so why do you need a specially formulated rubber lubricant? As evidenced by practice, many pump manufacturers recommend against the use of petroleum, petroleum jelly, or other petroleum or silicone-based products for lubrication of elastomer seals. Welcome to follow Pump Friends Circle. Use of these products can cause seal failure due to elastomer expansion. Rubber lubricant is a temporary lubricant. Once dry, it no longer lubricates and parts remain in place. Additionally, these lubricants do not react in the presence of water and do not dry out rubber parts.
