Misting pump maintenance

Keeping Your Mist Pump In Top Running Condition

As with most pieces of equipment, the most important factor in extended life is proper maintenance.  This is one thing that is the total responsibility of the mist system installer or the end user.  The recommended maintenance includes an annual review of the misting pump and all of its working components.  This can be done by the end user, the contractor who installed the system, or by Fogco at its facility.

The most critical ongoing maintenance items that should be closely watched by the end user or whoever is providing the maintenance to the misting pump  include the changing of the oil, the changing of the filter cartridge, the periodic checking for water or oil leaks, and the periodic checking of the critical components to be sure everything is working properly.

Suggested Maintenance for Any Misting Pump

As with your car, the misting pump uses oil to maintain lubrication and cooling within the crankcase.  It is easy to assume all is well because the pump continues to run, but if you wait until something fails, it will be too late.  The initial oil change should be once the pump is broken in after the first 50 hours of operation.  After that, oil changes should be made every 500 hours of operation.  All Fogco pumps include an hour meter to determine the proper time for the needed oil change.

The filters on the misting system are the last line of defense to prevent debris from entering the pump.  The cartridges should be inspected monthly and replaced at least once a year.  Dual filtration is also a good idea for areas that have extremely hard water or misting systems that are using well water.

In addition to oil and filter cartridge changes, all water pumps have rubber seals that are designed to wear (this is a necessity in order for the rubber material used to be able to seal around the pistons that create the pressure in the misting pump) and will need to be replaced whenever the pump begins to leak.  Typically, this will be between 500 and 2000 hours of operation depending on the specific misting pump design, the operating conditions, and the overall condition of the water supply.  The pump should be checked for water leaks every time the oil is changed.

Lastly, for all pulley drive pumps, the pulley belt should be checked each time the oil is changed.  If cracking or splitting of the belt is observed, the belt should be replaced.

Beyond the maintenance of the misting pump, there are other steps that can be taken to ensure a long life.  For pulley drive pumps, the motor pulley and the pump pulley must be perfectly aligned to ensure proper operation of these two critical components.  If you have any questions about the alignment of the pulleys, contact our Customer Service Department for steps to be taken.

The water supply to the pump is also an important factor.  It should be of sufficient quantity (at least twice the rated flow for the misting pump), sufficient pressure (most of the Fogco misting pumps include a low water pressure safety switch which will prevent the pump from operating if the water pressure is too low), and properly filtered.

The operating temperature of the misting pump should be as low as reasonable.  It is true that most misting pumps are placed in the outdoors and the Fogco pumps are designed and built anticipating this reality.  All of our enclosed pumps include an automatic exhaust fan to help maintain the temperature inside the enclosure as well as utilizing an over-sized bare pump so that the misting pumps rpm is reduced.  This has the effect of reducing the heat generated by the pump as well as extending its life by reducing the amount of cycles required to produce a given amount of flow.  However, if the mist pump can be placed in a enclosed area with a controlled environment, it can dramatically increase the pumps life.
