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. Barnes® Pumps are products

engineered and manufactured of high quality components.

Over one hundred years of pump building experience

along with a continuing quality assurance program combine

to produce a pump which will stand up to the toughest

applications.

This Barnes Pumps manual will provide helpful information

concerning installation, maintenance, and proper service

guidelines.

B-2) Receiving

Upon receiving the pump, it should be inspected for

damage 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 - Barnes Pumps are manufactured for efﬁ cient

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.

If extended high humidity is expected to be a problem, all

exposed parts should be inspected before storage and all

surfaces that have the paint scratched, damaged, or worn

should be recoated with a water base, air dry enamel paint.

All surfaces should then be sprayed with a rust-inhibiting oil.

SECTION C: PREPARE PUMP FOR OPERATION:

See Engine Manufacturer's instruction manual for

quantity, grade and viscosity of oil and change interval.

Fill engine crankcase with amount needed. and check oil

level frequent. Fill fuel tank per manufacturer,s

recommendations. Be familiar with engine START UP

and SHUT DOWN procedures before operation.

Operate engine in accordance with the manufactures

instructions.

Check oil level in the pump transmission. If it is not up to

the oil level plug in the cover, top off with an

SAE 80 - 90 EP gear lube. Transmission oil capacity is

20 oz. (550 ml).

HOME

For best performance locate pump as close to water as

possible. Vertical suction lift should not exceed

25 ft. (7.6M) At high lifts, 15 ft. (4.5M) and up, a foot

valve is recommended. When using suction hose, make

sure the gasket in the female ﬁ tting at the pump end is in

place and in good condition. When using pipe, coat the

threads with a thread sealing compound.

Suction hose must be in good condition with no leaks and

lining tight. A loose lining will collapse under suction and

keep liquid from being drawn into pump. A coarse straine

at end of suction hose is advisable if there is a possibility

of pumping large, hard, unbreakable solids, such as,

rocks, wood, tin cans, etc., that could be caught between

connecting rod and water box, causing pump damage.

To lead water away, connect non-collapsible suction hose

to the discharge connection. Discharge hose should not

be smaller than suction hose and not kinked. It is helpful

to use a short piece of hose at any time, with open end

raised a foot or so above discharge connection. Discharge

head should never exceed 25 ft. (7.6M).

On high lifts, or if pump has been idle and valves are dry,

pour water into the discharge opening to help seal valves

and speed up priming.

Pump speed can be regulated with throttle control on

engine from full volume, 65 strokes, to about 40 strokes

for lesser volume and seepage. By regulating pump

speed to suction and discharge conditions, the intermittent

up and down movements of the liquid columns in the

suction and discharge hoses can be timed so they will

assist each other and smooth out the pump operation,

rather than act in opposition. Smoothest operation can be

determined by trying pump at several speeds.

Drain pump in freezing weather by removing drain plugs.

SECTION D: MAINTENANCE INSTRUCTIONS

Keep interior of pump and valves clean. When

pumping liquids containing foreign materials, ﬂ ush

out pump with clear water whenever possible.

Keep suction hose air tight and check for leaks and

loose lining, as these are major trouble sources

when priming.

Valves and valve weights must be straight, seat well

and have no cracks.

The capacity of a diaphragm pump will vary greatly

depending on the height of the suction lift and length of

discharge line. A discharge line which is too small, long

or high will cause:

A. Excessive bulging of diaphragm on down stroke.

B. Valves closing with loud snap.

C. Rough operation.

D. Engine overloads and slows down.

E. Reduced capacity.

Check all bolts frequently and keep them drawn

up tightly.
