1. Pump Specifications

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. Motor overloads.

E. Reduced capacity.

Check all bolts frequently and keep them drawn up

tightly.

TO CHANGE DIAPHRAGM:

A. Rotate connecting rod and crank to down position.

B. Remove four bolts at outer edge to take off water box.

C. Remove three bolts at connecting rod and take out

diaphragm.

D. Replace diaphragm with type designed for heavy

duty service as originally supplied with pump. Raised

ridges on diaphragm must ﬁ t in grooves in connecting

rod and bottom clamp plate. Insert three bolts and draw

up nuts snug.

E. Center diaphragm carefully over water box and clamp

with four bolts to pump frame.

TO CHANGE VALVE RUBBERS:

A. Remove suction and discharge connections and

remove valve rubbers.

B. Place new valve rubber between weight and binder

and insert and tighten 2 screws that hold them together.

Tighten ﬁ rmly but not so rubber is distorted, causing poor

seating.

C. Dowel pin in suction connection and on discharge side

of waterbox must enter hole in valve rubber to locate

valve in correct relation to valve opening.

Diaphragm pumps will handle ﬂ uids containing

considerable solids, however if mixture is too heavy to

be pumped, liquid must be added until it becomes

sufﬁ ciently ﬂ uid for pumping.

Neoprene and other rubbers can be furnished for the

diaphragm and valve rubbers when pumping ﬂ uids

containing considerable oils, greases or chemicals.

10. ENCLOSED GEAR CASE:

Change the grear case oil after the ﬁ rst 40 hours of

operation. Check every 40 hours of operation and keep

oil at level plug. Change at 500 hour intervals and

seasonally, often if oil is dirty. See Section C, Item #8.

SECTION E: TROUBLE SHOOTING

If your pump does not prime or operate properly, check the

following:

Pump may be too high above or far from water.

Leaks in suction hose or hose connection to pump.

Check if hose inner lining has loosened. If loose,

pump suction will cause lining to collapse and block hose.

Manual Index

Valves may not be seating properly due to

accumulation of residue or wear. They are held

between waterbox and suction and discharge

connections and leakage can occur unless clamped

tightly. Pour water in suction chamber to help seal valves.

Valves and valve weights must be straight, seat well

and have no cracks.

Check diaphragm for breaks or leaks.

Make sure that end of suction line is in position to allow

water to enter; it may be buried in muck or blocked in

other ways.

Pump will not operate properly under a positive suction

head condition.

Do Not allow any point of the suction hose to be higher

than the suction connection on the pump, as a trapped

air pocket can form and prevent priming.

SECTION: F REPLACEMENT PARTS

F-1 ORDERING REPLACEMENT PARTS:

When ordering replacement parts, ALWAYS furnish the

following information:

1. Pump model number. (F-2)

2. Pump serial number.(F-3)

3. Part description.

4. Item part number.

5. Quantity required.

6. Shipping instructions.

F-2 MODEL NUMBER:

This designation consist of numbers and letters which

represents the discharge size, series horsepower, motor

phase and voltage, speed and pump design. This number is

used for ordering and obtaining information.

F-3 SERIAL NUMBER:

The Serial Number block will consist of a six digit number,

which is speciﬁ c to each pump and may be preceded by

a alpha character, which indicates the plant location. This

number will also be sufﬁ xed with a four digit number, which

indicates the date the unit was built (Date Code).
