Page 5: General Information
SECTION 1 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. Centrifugal pumps use the centrifugal force principal of accelerating the liquid within a rotating impeller, and then collecting it and converting it to pressure head in a stationary volute. -

fully operable if atmospheric conditions approach those experienced in operation. Consult instruction manuals for other precautions concerning storage of individual components of pumping unit. Fresh lubricant should be applied to bearings upon removal of equipment from storage. Refer to motor manual. Uncrating: Vertical HVAC In-Line pumps are thoroughly inspected before shipment to assure they meet with your order requirements. -
Page 7: Installation
Remove the coupling guard, place lifting straps through the pump/motor pedestal. With the straps in place, the whole assembly can now be lifted and placed in position in the piping. SECTION 3 INSTALLATION Location: Several factors should be considered when selecting a location for the pumping. The unit should be accessible for both inspection and maintenance. -
Page 8: Wiring And Controls
Wiring and Controls: The electric motor power supply connections must conform to national and local codes. The motor ratings stamped on the motor nameplate must match the line voltage and wire capacity. DO NOT USE ANY OTHER VOLTAGE. SECTION 4 OPERATION Do not exceed the rated working pressure of the pump. -

source. Trapped air should be allowed to escape through the vent valve while filling. 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: Maintenance
SECTION 5 MAINTENANCE There should be no mechanical seal leakage except for a brief break in period. Mechanical seals should be replaced if they are leaking. Refer to the motor manufacturer’s instructions for periodic maintenance requirements. Check that electrical control equipment contacts are in good condition and clean. Bearing relubrication requirements –... -
Page 11: Repairs & Replacement
SECTION 6 REPAIRS AND REPLACEMENT Whenever any disassembly work is to be done on the pump, disconnect the power source to the driver to eliminate any possibility of starting unit. It is advisable that a qualified Pump service technician does the disassembly and reassembly of the pump. -
Page 12: Cleaning
Cleaning: Petroleum based cleaning solvents are flammable. Smoking or open flames in the vicinity of these solvents is extremely hazardous and must not be permitted. Disregarding this warning could result in grave personal injury. Clean all metal parts with a solvent. Use a bristle brush (not metal or wire) to remove tightly adhering deposits. -
Page 13: Type Rc
Press the mechanical seal (65) into the volute cover (11). Install the volute cover (11) onto the motor (19). Lubricate the O.D. of the shaft sleeve (14) and the I.D. of the opposite half of the mechanical seal using Dow Corning Molykote 111 Compound or equivalent (available from Motion Industries, 545 Olympic Drive, Athens GA 30601, USA, Phone: 706-353-7780, Fax: 706-546-1427). - Page 14 Lubricate the interior of the mechanical seal using Dow Corning Molykote 111 Compound or equivalent (available from Motion Industries, 545 Olympic Drive, Athens, GA 30601, USA, Phone: 706-353-7780, Fax: 706-546-1427) and install onto the shaft (6). Install the gland gasket and gland (17). Install and tighten casing bolts.

Page 15: Type Ds
Install all NPT fittings and tubing. Rotate by hand to insure that the parts do not bind. Assembly (Type DS): Install the lower bushing (72) into the casing (1). Install lower casing ring (7). Insert the shaft (6) into the impeller (2). Assemble with key (32) and impeller nut (24) Tighten the locking screws in the impeller nut (24). - Page 16 Use a wood block and pry bar toraise the rotating element up approximately ¼” (6 mm) to allow the coupling (314) to fit with the collar on the motor shaft (10). Hold the other coupling half (314) in place and install coupling screws, only hand- tight at this time.

Page 17: 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. ... - Page 18 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 ring and the impeller.
