DIAPHRAGM PRIMER

INSTALLATION
POSITIONING PUMP
Death or serious personal injury and
damage to the diaphragm primer or
components can occur if proper lifting
procedures are not observed. Make cer
tain that hoists, chains, slings or cables
are in good working condition and of
sufficient capacity and that they are po
sitioned so that loads will be balanced
and the diaphragm primer or compo
nents will not be damaged when lifting.
Suction and discharge hoses must be
removed from the diaphragm primer be
fore lifting. Lift the diaphragm primer or
component only as high as necessary
and keep personnel away from sus
pended objects.
Lifting
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
before attempting to lift existing, installed units
.
Mounting
Locate the diaphragm primer in an accessible
place as close as practical to the priming chamber
assembly. Level mounting is essential for proper
operation. The diaphragm primer may have to be
supported or shimmed to provide for level opera
tion and eliminate vibration.
ALIGNEMENT
When checking alignment, disconnect
the power source to ensure that the
pump will remain inoperative. Rotating
parts can catch clothing, fingers or
tools, causing severe injury to person
nel.
Adjusting the alignment in one direction
may alter the alignment in another direc
tion. Check each procedure after altering
alignment.
The alignment of the diaphragm primer and its
power source is critical for trouble-free mechani
cal operation. In either a flexible coupling or belt
driven system, the driver and diaphragm primer
must be mounted so that their shafts are aligned
with and parallel to each other. It is imperative that
alignment be checked after the pump and piping
are installed, and before operation.
When mounted at the Gorman-Rupp factory, driv
er and diaphragm primer are aligned before ship
ment. Misalignment will occur in transit and han
dling. Pumps and diaphragm primers must be
checked and realigned before operation. Before
checking alignment, tighten the foundation bolts.
The pump, diaphragm, and power source mount
ing bolts should also be tightly secured.
Coupled Drives
When using couplings, the axis of the power
source must be aligned to the axis of the pump
shaft in both the horizontal and vertical planes.
Most couplings require a specific gap or clearance
between the driving and the driven shafts. Refer to
the coupling manufacturer's service literature.
