system components. Perform
routine maintenance s required (see
Maintenance Section).
10. Provide a means of pressure relief
for pumps whose discharge line can
be shut off or obstructed.
11. Personal Safety:
a. Wear safety glasses at all times
when working with pumps.
b. Wear a face shield and proper
apparel when pumping
hazardous chemicals.
c. Keep work area clean,
uncluttered, and properly lighted
- replace all unused tools and
equipment.
d. Keep visitors at a safe distance
from the work area.
e. Make workshop childproof – with
padlocks, master switches and
by removing starter keys.
12. For air drive units follow Safety
Information in instruction sheet
supplied with air motor.
Assembly
1. HANDLE ON 2" PUMP (Refer to
Figure A)
a. Remove two hex cap screws
(Ref. No. A6) and washers (Ref.
No. A7) from gearbox (Ref. No.
A1).
b. Place handle (Ref. No.
A35) on
gearbox flange and align holes.
c. Reinstall two hex cap screws
and washer assemblies, then
tighten.
HANDLE ON 3" PUMP (Refer
to Figure A)
a. Remove two hex nuts (Ref. No.
A14) from pump well (Ref. No.
A3).
b. Place handle (Ref. No.
A35)
under pump well.
c. Reinstall two hex nut and
washer assemblies, then
tighten.
2. ROTATING
SUCTION/DISCHARGE PORTS
(OPTIONAL) (Refer to Figure
A,W,P)
In some applications, it may be
preferable to have suction/discharge
ports rotated 90 degrees to be in line
with driver. If so, proceed as follows:
a. Remove four hex cap screws
(Ref. No. A9), hex nuts (Ref. No.
A13 & A14) and washers (Ref.
Nos. A11 & A12) from pump
assembly to separate pump well
(Ref. No. A3) from pump base
(Ref. No. A8).
b. Rotate pump well 90 degrees
clockwise so that driver is
positioned over top of
discharge plate (Ref. No. W7).
c. Be sure that pump well base
and diaphragm (Ref. No. P17)
are aligned properly with one
another. Then, reinstall four
hex cap screws, hex nuts and
washer assemblies and
tighten.
GEAR BOX OIL (Refer to Figure A,G)
3. Place pump on a level surface.
Fill pump gear box (Ref. No. A1)
with gear box oil before the pump
is operated. Gear oil must meet
requirements of API GL-5 and
military specification MIL-L-
2105B. Remove gear box
housing fill plug (Ref. No. G6).
Remove level plug (Ref. No. G5).
Pour gear oil into gear box slowly
until oil comes out of level plug.
Warranty on this
unit is void
unless the gear
box is lubricated with appropriate
gear oil listed above. DO NOT
OVER FILL!
Installation
NOTE: In any installation where
property damage can occur by
pumps not operating due to power
outages, discharge line freezing or
any other reason, a backup
system(s) and/or warning
system(s) should be used.
1. Place the pump on a level, solid
foundation, locating it as close to
the liquid as possible, making the
suction line as short and direct as
possible.
2. Install pipe nipples (Ref. No.
A36)
so the smoother side of pipe end
faces the suction and discharge
hose.
Maximum
discharge head is
25 feet or 10.9 psi. Operation over
this head or pressure will cause
pump to stall and/or gearbox
damage. Use only rigid hoses.
3. Attach suction piping to the
suction inlet (Ref. No.
W2) and
discharge piping to the discharge
outlet (Ref. No. W7). The suction
line should be positioned such
that there is a continual upward
slope from the fluid source to the
pump. Avoid using loops or
sections of pipe or fittings which
might permit air to become
trapped.
NOTE: If hose is used, be sure to use
reinforced hose on both the suction
and discharge. DO NOT USE canvas
or similar collapsible materials.
NEVER USE PIPE REDUCER;
PIPE SIZE MUST BE EQUAL TO
OR LARGER THAN PUMP PORT
SIZE. Suction line must be airtight so
that air cannot leak in and destroy
priming vacuum. On a permanent
installation where piping is used,
always connect a piece of flexible hose
between pump and piping so pump is
free to move slightly.
4. It is advisable to use a strainer
(Ref.
No. W16) on the inlet end of
the suction hose or pipe. A
properly sized strainer is supplied
with this unit and should be used
at all times to prevent damage.
Keep the strainer clean. If
possible, suspend it to keep it from
becoming clogged with muck,
roots, debris or leaves. It is best to
keep hose free of kinks as they will
restrict flow and add excess
loading to pump and gearing.
5. GASOLINE ENGINE UNITS:
Follow all instructions in the engine
manual before starting the engine.
Fill engine with oil, gasoline, etc.
AIR MOTOR UNITS: Follow
all instructions in the air motor
manual before starting unit.
ELECTRIC MOTOR UNITS: It
is strongly recommended that
this unit is plugged into a
G.F.I. (Ground Fault
Interrupter) circuit. Consult
your local electrician for
installation and availability.
6. Input RPM (to pump) – Input RPM
must be between 1750 and 2750
RPM. Final pump speed will be 40
strokes/min. with a 1750 RPM
input and 60 strokes/min. with a
2750 RPM input.
Do not exceed 60
strokes per
minute with the diaphragm pump.
