SECTION I
GENERAL INFORMATION
This manual covers the installation, operation and maintenance of Patterson Pump Type HSC pumps.
The pump is a centrifugal, single stage; single suction type furnished with mechanical seals. 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.
The pump consists of two assemblies:
1. Volute assembly or stationary part
2. Rotating element or moving part
The back pullout design allows for removal of the motor and integral rotating element without disturbing
the suction and discharge piping. The suction and discharge nozzles are drilled and tapped for gauge
connections. Pump casings are drilled and tapped for complete pump drain. Casing wear rings are
provided as standard equipment.
SECTION II
STORAGE & PROTECTION
All pumps are shop serviced and ready for operation when delivered, but there are occasions when
considerable time elapses between the delivery date and the time the pump is put into operation.
Equipment which is not in service should be kept in a clean, dry area. If equipment is to be stored for
long periods of time (six months or more), the following precautions should be taken to insure that the
equipment remains in good condition.
1. Unpainted-machined surfaces, which are subject to corrosion, should be protected by some
corrosive resistant coating.
2. The shaft should be rotated 10 to 15 revolutions by hand periodically in order to spread the
lubricant over all the bearing surfaces. Suitable intervals are from one to three months,
depending on atmospheric conditions, etc. In order to insure that the pump shaft does not begin
to sag, do not leave the shaft in the same position each time.
3. Space heaters on motors and controllers should be connected and fully operable if atmospheric
conditions approach those experienced in operation. Consult instruction manuals for other
precautions concerning storage of individual components of pumping unit.
4. Fresh lubricant should be applied to bearings upon removal of equipment from storage.
