Page 4: Section I
SECTION I GENERAL INFORMATION This manual covers the installation, operation and maintenance of Patterson Pump vertical inline pumps. The pump is a centrifugal, single stage close-coupled type. When properly installed and when given reasonable care and maintenance, centrifugal pumps should operate satisfactorily for a long period of time. -
Page 5: Installation
SECTION III INSTALLATION Location: Several factors should be considered when selecting a location for the pumping. The unit should be accessible for both inspection and maintenance. Headroom should be provided for the use of crane, hoist or other necessary lifting devices. The pump should be located as close as possible to the liquid supply so that the suction line is short and direct. -
Page 6: Shutdown
If the pump operates on a suction lift and no foot valve is provided, use a vacuum pump or ejector operated by air, steam, water, etc. to evacuate air from the pump case and suction line by connecting the ejector to the priming connection on top of the pump case. -

Page 10: Locating Operation Difficulties
LOCATING OPERATING DIFFICULTIES In the majority of cases, operating difficulties are external to the pump and the following causes should be carefully investigated before undertaking repairs: No Water Delivered Pump not primed indicated by no pressure on discharge. Speed too low indicated by low pressure on discharge. - Page 11 Pump Overloads Driver Speed too high. Head lower than rated, hence, pumping too much water. (This is valid for low specific speed pumps). Mechanical defects: stuffing boxes too tight, shaft bent, rotating element binds. Rubbing due to foreign matter in the pump between the case rings and the impeller. Pump Vibrates Misalignment.
