Only qualified personnel should install, operate and repair
pump. Any wiring of pumps should be performed by a qualified
electrician.
WARNING ! To reduce risk of electrical shock, pumps
and control panels must be properly grounded in
accordance with the National Electric Code (NEC) or
the Canadian Electrical Code (CEC) and all applicable
state, province, local codes and ordinances. Improper
grounding voids warranty.
WARNING! To reduce risk of electrical shock, always
disconnect the pump from the power source before
handling or servicing. Lock out power and tag.
WARNING! Operation against a closed
discharge valve will cause premature bearing
and seal failure on any pump, and on end
suction and self priming pump the heat build
may cause the generation of steam with resulting dangerous
pressures. It is recommended that a high case temperature
switch or pressure relief valve be installed on the pump body.
CAUTION ! Pumps build up heat and pressure
during operation-allow time for pumps to cool
before handling or servicing.
WARNING ! Do not pump hazardous materials
(flammable, caustic, etc.) unless the pump is specifically
designed and designated to handle them.
WARNING ! Do not wear loose clothing that may
become entangled in moving parts.
WARNING ! Keep clear of suction and discharge
openings. DO NOT insert fingers in pump with power
connected.
Always wear eye protection when working on pumps.
Make sure lifting handles are securely fastened each
time before lifting. DO NOT operate pump without safety
devices in place. Always replace safety devices that
have been removed during service or repair. Secure the
pump in its operating position so it can not tip over, fall
or slide.
DO NOT exceed manufacturers recommendation for
maximum performance, as this could cause the motor
to overheat.
WARNING ! To reduce risk of electrical shock, all wiring
and junction connections should be made per the NEC
or CEC and applicable state or province and local
codes. Requirements may vary depending on usage
and location.
WARNING! Products returned must be cleaned,
sanitized, or decontaminated as necessary prior to
shipment, to insure that employees will not be exposed
to health hazards in handling said material.AllApplicable
Laws And Regulations Shall Apply.
Bronze/brass and bronze/brass fitted pumps may
contain lead levels higher than considered safe for
potable water systems. Lead is known to cause cancer
and birth defects or other reproductive harm. Various
government agencies have determined that leaded
copper alloys should not be used in potable water
applications. For non-leaded copper alloy materials of
construction, please contact factory.

GENERAL INFORMATION
To The Purchaser:
Congratulations! You are the owner of one of the finest
pumps on the market today. These pumps are products
engineered and manufactured of high quality components.
With years of pump building experience along with a con-
tinuing quality assurance program combine to produce a
pump which will stand up to the toughest applications.
Check local codes and requirements before installation.
Servicing should be performed by knowledgeable pump
service contractors or authorized service stations.
Receiving:
Upon receiving the pump, it should be inspected for dam-
age or shortages. If damage has occurred, file a claim
immediately with the company that delivered the pump.
If the manual is removed from the crating, do not lose or
misplace.
Storage:
Short Term - Pumps are manufactured for efficient
performance following long inoperative periods in storage.
For best results, pumps can be retained in storage, as
factory assembled, in a dry atmosphere with constant
temperatures for up to six (6) months.
Long Term - Any length of time exceeding six (6) months,
but not more than twenty four (24) months. The units
should be stored in a temperature controlled area, a roofed
over walled enclosure that provides protection from the
elements (rain, snow, wind blown dust, etc..), and whose
temperature can be maintained between +40 deg. F and
+120 deg. F. Pump should be stored in its original shipping
container and before initial start up, rotate impeller by hand
to assure seal and impeller rotate freely.
Service Centers:
For the location of the nearest Weinman Service Center,
check your Weinman representative or Crane Pumps &
Systems, Inc., Service Department in Piqua, Ohio, telephone
[phone] or Crane Pumps & Systems Canada, Inc.,
Bramton, Ontario, [phone].
INSTALLATION
FOUNDATION
Weinman Motor-Mount Pumps can be installed on any
sufficientlysolidfoundationsincepumpand motor are rigidly
aligned. The unit may be installed on a concrete foundation
with anchor bolts set in place or securely mounted on a wall
in either a horizontal or vertical position with motor above
pump. The pump should be located as near the source
of supply as possible with a minimum of suction pipe and
elbows.
PIPING
A foot valve and strainer must be installed on the lower end
of the suction pipe to keep pump completely filled with liquid
whenthepump isusedunder suctionliftconditions.Connect
suction pipe to pump, making certain that all connections
are airtight. When a foot valve and a strainer are used, it is
necessary to install a check valve in the discharge line near
the pump to prevent possible casing damage due to line
shock or surge when the pump stops. A gate valve should
also be installed in the discharge line. Connect discharge
pipe to pump casing.
It is important that the suction and discharge pipes “line up”
naturally with the pump. Do not “pull” pipes into position
with flange bolts or fittings. Support pipes independently of
the pump to eliminate any strain on the pump. Turn shaft to
see that it rotates freely. If rotor binds, it indicates a strain on
the casing, which must be corrected before operating pump.
It may be necessary to shim motor at foundation to assist
piping connection line-up.
WIRING/ROTATION
Check motor name plate for electrical characteristics. Be
sure they are the same as the rating of the electric power
available. Connect power lines to motor in accordance with
the wiring diagram on the motor. Test rotation by jogging
motor. Shaft must rotate in the direction indicated by arrow
cast on pump casing.
OPERATION
PRIOR TO STARTING
Be sure the following important items are checked before
starting.
1. Pump and driver bolted securely.
2. Piping complete.
3. Motor properly lubricated. Follow the recommendations
found in the Maintenance Section of this manual.
4. Open the seal flush valve, if used.
5. Shaft turns freely.
6. Rotation is correct. The pump must rotate in the
direction of the arrow on the casing.
7. Discharge valve. A high or medium head centrifugal
pump operating at full speed with the discharge valve
closed, requires much less power than when operating
at its rated head and capacity with the discharge valve
open. For this reason, it is usually best to have the
discharge valve only partially open when starting the
pump.
WARNING !
Operating the pump with a closed or partially open
discharge valve can result in excessive heat buildup.
Such operation should be limited to the shortest
practical duration. Operating the pump at or near shut-
off head places greater loads on the shaft and motor
than operation at the designed flow rate and head,
8. Suction valve, if used, must be fully open. Do not use
suction valve as a throttling device

PRIMING
The pump casing and suction pipe must be completely
filled with liquid before operating the pump.
Pump priming may be accomplished by one of the
following methods. The discharge gate valve should be
closed during priming.
PRIMING BY SUCTION PRESSURE
When operating with suction pressure (flooded suction),
remove the pipe plug at the top of the casing and when
pump is filled with liquid, replace plug.
PRIMlNG WITH FOOT VALVE AND STRAINER
Afootvalve andstrainermay beinstalledon thelowerendof
the suction pipe to keep pump filled with liquid. Incorporate
filler pipe in discharge pipe between pump and check valve.
Remove pipe plug at top of casing, then fill suction pipe and
pump with liquid. When pump is full of liquid, replace plug
and close filler pipe.
CAUTION: When a foot valve and strainer are installed on
the suction pipe, a spring loaded type check valve MUST be
installed next to the pump in the discharge piping to prevent
pump rupture from water hammer shock.
Priming by means of primer pump or ejector, attached to
the pump, will also remove air from suction pipe and pump
casing. When pump is filled with liquid, start motor and
slowly open discharge gate valve.
STARTING
Start the pump. When the pump has reached its designed
operating speed slowly open the discharge valve to obtain
the desired capacity and pressure.
With the pump running, carefully check for unusual
vibration, quiet operation, mechanical seal function and
unusually high temperature.
WARNING
Never try to adjust or work on the pump while it is
running. Always stop the unit completely before
attempting any adjustment.
MAINTENANCE
1. LUBRICATION - Motor bearings should have periodic
attention and lubrication in accord with motor
manufacturer’s recommendations. Under ordinary
conditions a ball bearing will run from 100 to 600
Fahrenheit above ambient temperatures. Unless
bearing temperature runs extremely hot do not become
alarmed.
2. MECHANICAL SEAL - Only mechanical seals are
available on this pump. By their nature, a properly
lubricated mechanical seal requires no maintenance.
REPAIR
WARNING
If Pumping Any Fluid That Could Cause Bodily
Injury (Hot water, caustic, etc.), Always Use Eye
Protection and Wear Protective Clothing Over All
Exposed Body Areas.
REMOVE AND LOCK-OUT POWER TO THE
DRIVER WHILE PERFORMING THESE TASKS
