FETY PRECAUTIONS
WARNING
Do not operate this equipment in excess of its rated speed or other than in accordance with the
instructions contained in this manual.
The equipment has been found satisfactory of the conditions for which it was sold, but its operation in
excess of these conditions may subject it to stresses and strains which it was not designed to withstand.
For equipment covered by this instruction book, it is important to observe safety precautions to protect
personnel from possible injury.
avoid contact with rotating parts
avoid bypassing or rendering inoperative any safeguards or protective devices
avoid extended exposure in close proximity to machinery with high noise levels
use proper care and procedures in handling, lifting, installing, operating and maintaining the
equipment
do not modify this equipment consult factory if modification is deemed necessary
do not substitute for repair parts which can be provided by the e
Safe maintenance practices with qualified personnel are imperative.
Failure to heed this warning may result in an accident causing personal injury.
Among the many considerations, personnel should be instructed to:
quipment manufacturer.

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. 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 consist
1.
Volute assembly or stationary part
2.
Rotating element or moving part
The back pullout design casing allows removal of the impeller and rotating element without disturbing
suction and discharge piping. The suction and discharge flanges are on a common centerline 180
degrees apart. Suction and discharge flanges are drilled and tapped for gauge connections. The volute
is drilled and tapped on the underside 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 is 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
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 must be applied to bearings upon removal of equipment from storage.
Refer to
-machined surfaces, which are subject to corrosion, should be protected by
motor manual.

SECTION III
INSTALLATION
3-1
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. Location should require a minimum of elbows and
fittings in the discharge line t
3-2
The pump unit is designed to be installed in the pipeline. Standard piping supports on either side of the
pump should be us

The suction and discharge pipes must be in line, and the pump must not be used to pull the piping into

The electric motor power supply connections mush conform to national and local codes. The
motor ratings stamped on the motor nameplate must match the line voltage and wire capacity

Starting:
Turn the pump shaft by hand to insure that the parts do
Open the valve in the pump suction line, if fitted
Close discharge valve
Prime the pump in one of the following ways:
If the pump operates under positive pressure, open vent valve on top of the pump casing. After
all entrained air has escaped, close the vent valves. Rotate the shaft, if possible, to allow any air
trapped in the impeller passages to escape.

2.
If the pump operates on a suction lift and a foot valve is included in the system, fill the pump and
the suction line with liquid from an outside source. Trapped air should be allowed to escape
through the vent valve while filling.
