What Does Annual Pump Maintenance Usually Include?

0 14

Pumps can be used in a wide variety of applications and environments. Due to their versatility, they are available in many types, including submersible pumps, jet pumps, domestic pumps, and variable-frequency drive pumps, to name a few. Although many pumps are available, preventative maintenance is crucial for all pumps to help spot issues early on and discourage pump failure. Having annual pump maintenance performed is one of the most effective ways to utilize preventative maintenance measures for your pump.

Why Is Annual Pump Maintenance Important?

Whether you are running a pump in your pond, a well pump, or a sewage treatment system, annual pump maintenance is integral to keeping your system running reliably and maximizing the lifespan of your pump.

Different parts make up your pump, and all require periodic attention to inspect their shape. Unfortunately, without regular inspection and maintenance, you may be unaware of a problem with your pump until after it becomes an even bigger problem and possibly a more costly repair. For example, a trained pump technician may be able to spot a potential problem in a well-water system during regular maintenance, perhaps avoiding a water outage in your home for an extended amount of time.

What Does It Include?

The type of maintenance performed will vary depending on several factors, including the type of pump and who conducts it. However, there are some things to look for in an annual pump maintenance program.

Non-Clog Pumps

Yearly maintenance usually includes inspecting and greasing the motor, checking the valve, floats, AMPS, oil, and time cycling.

Domestic And Booster Pumps

Yearly preventative maintenance and service on domestic and booster pumps should include inspecting electrical capacitors, pressure switch, and control box, inspecting plumbing valves and air changing system, inspecting the tank itself, obtaining water levels, and checking motor wear, as well as checking AMPS.

Turbine Pumps

For best results, turbine pump maintenance should include inspecting the tube, shaft, motor fans, controls, and discharge, serving the pump and motor, greasing the motors, adjusting the auto oiler, and obtaining water levels.

Variable Drive VFD’s

The pumps should have yearly maintenance, including inspecting the fans, connections, thermostats, fan relays, and displays, cleaning or replacing the filters, and blowing out the heat sinks and cabinets.

Can I Perform Pump Maintenance Myself?

The maintenance required can vary greatly depending on the pump’s type and application. Also, the location of many pumps can make maintenance or repairs tricky without the proper training and equipment, so it’s usually best to have a professional pump specialist complete servicing and maintenance. However, there are some things that you can do yourself to look for any obvious signs of a problem.

If your pump is above the ground, you may be able to spot some warning signs of a problem, such as leaking water. However, submersible pumps are significantly more challenging for you to evaluate the condition since it is submerged in water. Still, you can pay attention to any alarms that your system is displaying or look for signs of a clog, such as low water pressure and call a pump specialist.

Signs of Pump Trouble

If you detect any of these items, you should call a pump specialist as soon as possible:

Loud or Unusual noises

Hearing a humming sound when the pump is running is normal. However, one of the first signs of a problem with your pump can be hearing abnormally loud noises, clunking, or crunching sounds.


Since the mechanical seals are a wearing part, they should be routinely replaced and can be a leaking point on a pump. The stuffing box can be a leaking point as well. Look for signs of a water leak, such as mold or damp spots.

Excessive Vibration

If you notice your pump seems to be vibrating excessively, this could be cause for concern. A pump should not overly vibrate, and some causes could include impeller imbalance or damage or misalignment of the pump and motor.


If the pump casing, motor, or bearings seem to be getting overly hot, this could indicate rubbing or wearing of parts, that the pump has been running against a deadhead, or it has been trying to run in a capacity that it cannot handle or maintain, causing excessive strain.


Corrosion can weaken your pump’s casing and components, causing pump failure and possibly contaminating your water. Therefore, any signs of rusting, cracking, or discoloration should cause concern.


Even small solids can cause your pump to clog if it isn’t made for it. You can notice the signs of a clog by paying attention to water flow and pressure.

Whether being used in an industrial, residential, or municipal setting, we rely heavily on pumps in our day-to-day lives. Although you may not think about pump maintenance until after there is already a problem, proper upkeep will discourage premature failure of your system and save money down the road. Having regular pump maintenance performed is a highly effective preventative maintenance measure that you can take to maximize the longevity of your pump.
