POSITIONING PUMP
Lifting
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi
cient capacity and that they are posi
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis
charge hoses and piping must be re
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
Pump unit weights will vary depending on the
mounting and drive provided. Check the shipping
tag on the unit packaging for the actual weight, and
use lifting equipment with appropriate capacity.
Drain the pump and remove all customer‐installed
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mount
ing is essential for proper operation.
The pump may have to be supported or shimmed
to provide for level operation or to eliminate vibra
tion.
To ensure sufficient lubrication to the engine,
do
not
position the pump and engine more than 15
_
off horizontal for continuous operation. The pump
and engine may be positioned up to 30
_
off hori
zontal for
intermittent operation only
; however,
the engine manufacturer should be consulted for
continuous operation at angles greater than 15
_
.
Clearance
When positioning the pump, allow a minimum
clearance of
18 inches (457,2 mm)
in front of the
enclosure suction cover to permit removal of the
cover and easy access to the pump.
NATURAL GAS FUEL
The amount of natural gas fuel required for the en
gine is measured in cubic feet per hour. This is cal
culated from the BTU (British Thermal Unit) con
tent of the natural gas supplied, and the horsepow
er required to drive the pump.
This unit requires
1,141 CF/hr of natural gas with 1000 BTU con
tent at 10 inches of water column.
The BTU con
tent of gas varies in the United States, therefore, it
will be necessary to contact your local gas supplier
to determine the BTU content of the natural gas in
your area.
When burning natural gas having a BTU content of
1000 or over, the engine will deliver the rated horse
power as shown on the pump Specification Data
Sheet. On lower grade natural gas, there will be a
power loss of approximately 3% for each 100 BTU
under 1000.
Natural gas pressures provided by suppliers vary,
so in order to provide the optimal gas supply to the
engine, Gorman‐Rupp has provided a regulator
with the unit that can be adjusted to provide 10
inches of water column of gas pressure to the en
gine. Install the pressure regulator supplied with
the unit in the line supplying the engine, then check
and adjust the fuel pressure as described in
CON
NECTING FUEL SUPPLY LINE TO THE UNIT
.
LPG FUEL
The term Liquefied Petroleum Gas (LPG) refers to
any one of many butane/propane compounds,
some of which have additives for specific applica
tions. Commercial grade propane is recommend
ed.
