Diaphragm Pump 8301
DESCRIPTION
The Model 8301 Air-Powered Diaphragm Pump is
used to transfer corrosive chemicals. The wetted
parts are polypropylene and the diaphragms are
Santoprene to resist damage from caustics, plating
liquids, brine water and other corrosive chemicals. A
silencer enclosed in the body reduces the noise. The
pump delivers a maximum capacity of fourteen
gallons per minute.
The pump has the following outstanding features:
1. Leak-Free Flange Connections
2. Side-Outlet Port Design
3. Non-Leak Manifold
4. Corrosion-Resistant Air Motor
5. Abrasion-Resistant Housing
6. Air-Valve Reset Button
7. Air Valve Requires No Lubrication

GENERAL SAFETY REQUIREMENTS
IMPORTANT: Read all instruction sheets and any
other explanatory information before beginning any
installation, operation or maintenance.
1. Check all hoses and lines for weak or damaged
condition and make sure that all connections are
secure.
NOTE: Worn or damaged parts threaten person and
property. Replace all such parts.
2. Do not use pump with any liquids not compatible
with the materials of the pump components.
3. Never exceed the maximum pressure rating of any
component in the system.

4. Never point the dispensing device at anyone.
Accidental discharge can cause serious injury.
5. Shut off the air pressure and relieve all material
pressures before attempting to service any part.
6. Check for leaks before starting any pumping
operation. If any leaks or other abnormalities are
found, do not operate the pump.
7. Wear safety glasses at all times when operating
the pump.
8. Wear a face shield and proper body protection
when working with hazardous chemicals.
9. When pumping Class 1 Hazardous (flammable)
liquids, use pump outdoors or in an OSHA approved
location.
10. When pump is used with flammable or Class 1 ma-
terials,thefollowingproceduresmustbestrictlyapplied:
A. A special “static hose” must be used which has
a provision for conducting static electrical charges.
B. Hose must be properly grounded with a
grounding conductor.
C. Pump and entire system must be properly
grounded, in accordance with local and national
codes.
WARNING: Unless proper grounding is followed,
static discharge can cause a fire or an explosion.
INSTALLATION
There are many possible configurations in which the
pump can be connected. Specific installations will
depend on the fluid being pumped and the application.
NOTE: For best results, it is recommended that an
air filter/moisture separator (such as the Alemite
5604-2) and an air-pressure regulator (such as the
Alemite 7604-B) be used in the air line.
WARNING: The pump must be grounded to prevent
anysparkswhenpumpingflammableorvolatileliquids.
NOTE: The inlet and outlet manifolds are reversible
to facilitate connecting the hoses from either
direction.
1. Connect a suction hose from the supply container
to the pump fluid inlet.
2. Connect a discharge hose to the pump fluid outlet. Figure 2: Dimensions & Locations

NOTE: Use a flexible hose between the pump and
any piping to eliminate any vibration in the piping.
3. Connect a hose from the air supply to the inlet air
port.
NOTE: Make sure that the air-control valve on the
diaphragm pump is closed before connecting to the
air supply.
CAUTION: Maximum air pressure is 100 PSI. Do not
exceed this rating.
NOTE: Due to the plastic construction of the pump, it
is recommended that for all hardware connections,
standard torque values should be used. Pipe-thread
sealant should be used on all plumbing connections.
Over torquing of any component can lead to
distortion of plastic.
OPERATION
WARNING: Wear safety glasses at all times when
operating the pump. Always wear a face shield and
proper body protection when working with hazardous
chemicals.
NOTE: Check for leaks before starting any pumping
operation. If any leaks or other abnormalities are
found, do not operate the pump.
1. The positive-displacement pump is self priming.
To initially prime the pump, using either the control
valve on the pump or the air-regulator valve, bring
the air pressure up slowly.
NOTE: Due to the fact that air and air mixed with
material (which may be a corrosive chemical) can
discharge quite violently during this procedure, direct
the discharge outlet back to the source at this time. If
a reel is used, bring the reel outlet back to the
source. If the reel is too far away for the hose to
reach, bleed the air into a separate container until the
pump and hose are primed.
NOTE: If starting difficulty is encountered, press the
reset button which is located at the air valve.
2. When the pump and hose are fully primed, the
pump is ready for operation.
NOTE: If the pump is operated faster than the
allowable flow rate, it can cause cavitation. This will
reduce the rate flow of the fluid and also reduces the
life of the diaphragm.
3. To obtain the maximum discharge rate, start the
pump by opening the ball valve gradually while
watching the discharging fluid until the flow rate
begins to diminish. Then close the valve slightly to
get the maximum discharge rate.
SERVICE
Trouble-Shooting:
For the most common of problems, a trouble-
shooting chart is provided as a guide to most of the
corrective remedies. (See Table 1.)
