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 ! Never operate a pump with a plug-in type

power cord without a ground fault circuit interrupter.

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

(ﬂ ammable, caustic, etc.) unless the pump is speciﬁ cally

designed and designated to handle them.

CAUTION ! Do not block or restrict discharge hose, as

discharge hose may whip under pressure.

WARNING ! Do not wear loose clothing that may

become entangled in moving parts.

WARNING ! Keep clear of suction and discharge

openings. DO NOT insert ﬁ ngers 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.

SECTION B: GENERAL INFORMATION

B-1) To the Purchaser:

Congratulations! You are the owner of one of the ﬁ nest

pumps on the market today. CP&S pumps are products

engineered and manufactured of high quality compo-

nents. Over one hundred years of pump building experi-

ence along with a continuing quality assurance program

combine to produce a pump which will stand up to the

toughest applications.

This manual will provide helpful information concerning

installation, maintenance, and proper service guidelines.

B-2) Receiving:

Upon receiving the pump, it should be inspected for dam-

age or shortages. If damage has occurred, ﬁ le a claim

immediately with the company that delivered the pump. If

the manual is removed from the packaging, do not lose or

misplace.

B-3) Storage:

Short Term- CP&S Pumps are manufactured for efﬁ cient

performance following short inoperative periods in stor-

age. 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 unit

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. (4.4 - 49°C).

Pump should be stored in its original shipping container.

On initial start up, rotate impeller by hand to assure seal

and impeller rotate freely. If it is required that the pump be

installed and tested before the long term storage begins,

such installation will be allowed provided:

1.) The pump is not installed under water for more than

one (1) month.

2.) Immediately upon satisfactory completion of the test,

the pump is removed, thoroughly dried, repacked in

the original shipping container, and placed in a

temperature controlled storage area.

B-4) Service Centers:

For the location of the nearest Barnes or Prosser Center,

check your Barnes or Prosser representative or

Crane Pumps & Systems, Inc., Service Department in

Piqua, Ohio, telephone (937) 778-8947 or Crane Pumps &

Systems Canada, in Brampton, Ontario, (905) 457-6223.

SECTION C: INSTALLATION

C-1) Location:

These pumps are recommended for general and light

construction, for sump and dewatering drainage, for dewa-

tering manholes and transformer vaults, for pit, tunnel and

trench dewatering, and for ﬂ ood, ﬁ re and other emergency

service cleanup.

Before pumping ﬂ uids other than water, consult the

factory, giving ﬂ uid, ﬂ uid temperature, speciﬁ c gravity,

viscosity, capacity in USGPM and total head and/or pres-

sure requirements, including friction loss through dis-

charge line, ﬁ ttings, valves, etc. Pump may run dry for 5 to

10 minutes in air without damage where air can circulate

freely through the pump. DO NOT allow pump to be bur-

ied in mud or sand.

C-2) Discharge:

Discharge hose is recommended. If rigid pipe is used,

install so that there is no weight or strain on the pump.

C-3) Liquid Level Controls: (If Applicable)

Attach “ON” ﬂ oat to discharge hose or pump cable at

desired pump “ON” level. Attach “OFF” ﬂ oat to discharge

hose or pump cable at desired pump “OFF” level. The

“OFF” ﬂ oat must be below the “ON” ﬂ oat. To attach the

ﬂ oats, thread the cable strap through the buckle with

the ratchet pawl, cinch up tight, thread excess strapping

through outer buckle slot. Be certain the level controls

cannot hang up or foul in its swing. It is recommended that

the pump is completely submerged when the level control

is in the “OFF” mode.

C-4.1) Electrical Connections:

The pump comes with a three wire cord and a three prong

grounded plug on the 120 volt models and a three wire cord

without a plug on the 240 volt models.

The 120 volt model’s cord assembly should not be

modiﬁ ed in any way and must be connected into a three

wire grounded Ground Fault receptacle.

There are many different prong conﬁ gurations for 240 volt

applications. An appropriate 240 volt plug to match your

receptacle will be required. Make sure the plug meets the

pump amp requirements found on the nameplate. Follow

the plug manufacturer’s wiring installation instructions.

DO NOT USE THE POWER CABLE TO LIFT PUMP.

C-4.2) Overload Protection:

An automatic thermal overload protects the motor. The

type of in-winding overload protector used is referred to

as an inherent overheating protector and operates on the

combined effect of temperature and current. This means

that the overload protector will trip out and shut the pump

off if the windings become too hot or the current passing

through them becomes too high.

It will then automatically reset and restart the pump after

the motor cools to a safe temperature. In the event of an

overload, the source of this condition should be deter-

mined and rectiﬁ ed immediately. DO NOT LET THE

PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION

OCCURS!

SECTION D - START UP OPERATION

D-1) Check Pump Rotation:

Before putting pump into service for the ﬁ rst time, the

motor rotation must be checked. This is especially true

on 240 volt pumps after installing the appropriate cable

plug. Improper motor rotation can result in poor pump

performance and can damage the motor and/or pump. To

check the rotation, suspend the pump freely, momentarily

apply power and observe the “kick”. “Kick” should always

be in a counterclockwise direction as viewed from the top

of the pump motor housing. Pump “kick” is the opposite

direction of pump rotation.

D-2) Start Up:

DO NOT attempt to start a frozen pump.

Instead, submerge pump in water for twenty

minutes before starting. DO NOT attempt to

thaw a frozen pump with a torch.

D-3) Warranty Registration:

Fill in the Warranty Registration at the end of this manual

and send it in to our Warranty / Service Department. Also,

record the model number and date code numbers in

Section F-1 of this manual for future reference if needed.

SECTION E - PREVENTATIVE MAINTENANCE

The following procedure must be followed to assure

proper pump operation.

E-1) General Safety:

Frequent inspections shall be made. All electrical parts,

including the portable cable and wiring shall be kept in

a safe condition. KEEP CABLE GLAND NUT TIGHT.

CHECK FREQUENTLY. There shall be no openings in the

casing of the electrical parts. The operating voltage shall

match the voltage rating of the motor.

E-2) Servicing:

Pump shall be restored to the state of original safety with

respect to all lead entrances, etc. following disassembly.

E-3) Renewals and Repairs:

Special care shall be taken in making renewals and re-

pairs. Leave no parts off. Use replacement parts furnished

by the manufacturer. When any lead entrance is disturbed,

the original leads or exact duplicates thereof shall be

used.

E-4) Fasteners:

All bolts, nuts, screws and other means of fastenings shall

be in place, properly tightened and secured.

E-5) Cable Requirements:

Special care shall be taken in handling the cable (7)

against mechanical injury and wear. Connections and

wiring to the power source shall be in accordance with all

electrical and safety codes.

E-6) Shaft Seals:

The seals (12 & 16) should be inspected every 400 or

500 operating hours for wear (more often if abrasives are

present). To make a quick check of the seal’s condition,

drain and inspect the oil in the seal chamber (see Section

F1.1). If oil removed from the pump contains water or

abrasives, replace the seals.

SECTION F - SERVICE AND REPAIR

F-1) Lubrication:

F-1.1) Checking Oil - To check the seal chamber oil,

invert the pump and remove the screws (26) lockwashers

(11) strainer (25), suction case (24), impeller nut (15),

washers (14 & 22) and Impeller (21). Remove the socket

head screw (9) with o-ring (8) from the hole marked “OIL”.

With a ﬂ ashlight, visually inspect the oil in the seal cavity

to make sure it is clean and clear, light amber in color and

free from suspended particles. Milky white oil indicates

the presence of water. If the oil looks milky white, pour

the oil out of the oil chamber and let it settle in a clean

dry container. If any water settles out in the bottom of

the container or if the oil is white and thick (emulsiﬁ ed),

replace the mechanical seals and oil.

You can also check oil for contamination by using an oil

tester with a range to 30 Kilovolts breakdown. If oil is

found to be clean and uncontaminated (measure at or

above 15KV. Breakdown), reﬁ ll the seal cavity. If the oil

is found to be dirty, or contaminated (or measures below

15KV. Breakdown), replace the mechanical seals and oil.

F-1.2) Replacing Oil:

Follow steps in E-2.1 to remove socket head screw (9)

with o-ring (8) from the hole marked “OIL”. Turn pump

over to drain oil from seal chamber. Dispose oil properly.

Flush inside seal chamber of diffuser thoroughly to be

sure it is clean and free of abrasives. Reﬁ ll seal chamber

with 3 oz. (90 ml) of an approved oil. The oil shall be of a

highly reﬁ ned parafﬁ nic base, straight mineral oil, free of

all additives (called non-inhibited or non-detergent). Refer

to Table 1 for recommendations.

F-1.3) Seal Cavity Pressure Test:

Remove the socket head screw (9) and o-ring (8) from

the hole marked “OIL” and check for correct amount of

oil. Apply pipe sealant to pressure gauge assembly and

tighten into hole (See Figure 1). Pressure seal chamber

to 12 PSI and check for leaks. If after ﬁ ve minutes,

the pressure is still holding constant, and no leaks are

observed, slowly bleed the pressure and remove the

gauge assembly. Replace socket head screw (9) with

o-ring (8) using a sealant. If the pressure does not hold,

then the leak must be located and repaired.

F-2) Impeller Replacement:
