The root cause for the increase hasbeen simply the lack of or contamination of lubricants. Thousands of dollars are spent torepair equipment, which if properly lubricated and maintained would provide years Pumps will Provide the Following Services:xMeet with you and/or your staff to determine your needs and goalsxComplete an equipment survey using existing machinery records and a plant walkthroughxIdentify critical and non-critical equipment for the facilityxConduct a needs assessment for all equipment involvedxDetermine immediate repairs required prior to the start of the preventativemaintenance programxDesign a Program that meets the OEM s recommendations for maintenanceThe Following is an Example of the Work to be Performed to a Pumpand Motor During a Preventative Maintenance Visit.

4 Most pump Maintenance activities center on checking packing and mechanical sealsfor leakage, performing Maintenance activities on bearings, assuring proper alignment, andvalidating proper Motor condition and function without consideration for pump efficiency will decrease both Maintenance and operating Measures to Improve Pump down unnecessary internal clearances if performance has or change impellers if head is higher than by throttle instead of running wide-open or bypassing oversized multiple pumps instead of one large a small booster the speed of a pump for the most efficient match of horsepower requirementswith output. This also may be achieved by the installation of a variable speed Likely Candidates for Pump Efficiency MeasuresLarge Horsepower Pumps (25 HP or greater)(Listed in order of decreasing potential) pump Maintenance this is often associated with one of the following:oOversized pumps that are heavily throttledoPumps in cavitationoBadly worn pumpsoPumps that are misapplied for the present pump system with large flow or pressure variations.

5 When normal flows orpressures are less than 75% of their maximum, energy is probably being wasted fromexcessive throttling, large bypass flows, or operation of unneeded flow, either from a control system or deadhead protection orifices, is control valves. The pressure drop across a control valve represents wastedenergy that is proportional to the pressure drop and throttle operation. Pumps throttled at a constant head and flow indicate pumps or valves. A noisy pump generally indicates cavitation from heavythrottling or insufficient net positive suction head available (NPSHa). Noisy controlvalves or bypass valves usually mean a higher pressure drop with a corresponding highenergy Liberty StreetEdison, NJ 08837 Phone 732-738-6210 Fax , Parts, Systems, Engineering Services, Field & Shop Repairs, multiple pump system.

6 Energy is commonly lost from bypassing excess capacity,running unneeded pumps, maintaining excess pressure, or having a large flowdifferential between from design conditions. Changes in plant operating conditions (expansions,shutdowns, etc.) can cause pumps that were previously well applied to operate atreduced piece of equipment requiring low-flow with high-pressure. This equipment mayrequire operation of the entire pump with known overcapacity. Overcapacity wastes energy because more flowis pumped at a higher pressure than equipment specialist will be in contact with you shortly to set up an appointment.
