1. Operating Under Load
It is critical when operating a pump to never operate it at a higher flow rate or pressure than its design specifications as this can cause severe damage to the pump. Furthermore, it is also important to ensure that the pump operates at its maximum efficiency to prevent overworking of the motor. Overloading the pump can also cause problems such as not providing the necessary flow rate or abnormal pressure fluctuation.
2. Insufficient or No Cooling
The suction of well-ventilated air assists with cooling the pump. An inadequate amount or none at all can cause drastic temperature increase of the pump, leading to equipment failure or burning of the motor if it occurs for a prolonged period. It is important to pay attention to the ventilation around the pump and make sure there is a sufficient amount to assist with its cooling.
3. Foreign Objects In Pump
Foreign objects in a pump can cause excessive wear and tear to components, resulting in a reduction of efficiency and a potential increase in downtime. It is important to inspect the pump before beginning operation and make sure there are no pieces of debris or obstructions within the pump.
4. Mechanical Sealing
When operating a mechanical pump, attention should be given to the mechanical seal as its improper or poor installation can lead to significant problems with the pumps operation. In addition, any damage or excessive wear of the mechanical seal should be addressed immediately to ensure continued and efficient operation of the pump.
5. Over Oiling
Over oiling a pump can lead to the excess lubricant entering other parts of the system, resulting in oil being passed, or the lubricant leading to excessive oil-fouling. Moreover, over oiling of the pump can lead to sludging of oil which eventually leads to the contamination of other components, increasing wear and tear of parts and decreasing the efficiency of the pump.
6. Retrofitting
Retrofitting a pump is replacing old or damaged parts with new ones to return the pump to its standard performance. It is important to use the correct components and undergo the correct procedures to ensure that the equipment remains functional. Retrofitting a pump improperly can cause further damage to the pump and decrease its efficiency.
7. Failure to Consult the Manual
The manual and specifications provided are to be consulted before starting the operation and maintenance of a pump. Not doing so can lead to confusion and incorrect operations of the pump, leading to increased downtime. Failing to consult the manual may also lead to the improper use or misuse of auxiliary equipment which can cause severe damage to the pump and reduce its efficiency.
8. Operating Where Corrosion is Present
Pumps operating in areas with a significant amount of corrosion can result in the equipments metal surfaces becoming damaged. This corrosion can lead to blockages, clogs and metal shrinking if not tended to immediately, leading to a decrease in performance as well as an expensive repair. It is an important part of any maintenance program to inspect areas such as the filter screens, manual valves, and O-rings to ensure they are in the best condition.
