Introduction

WARNING

These pumps area designed to be used only in

pumping non-corrosive and non-abrasive lubricants

and greases. Any other use of the pump can cause

unsafe operating conditions and component rup-

ture, which can result in fluid injection or other

serious injury, or fire or explosion.

NOTE: Be sure that all operators read and understand

this entire manual and any separate manuals supplied

with components and accessories before using this

equipment.

NOTE: Reference numbers and letters used in the text

refer to the callouts in the figures and the parts dra-

wing.

Terms

WARNING: Alerts the user to avoid or correct condi-

tions that could cause serious injury.

CAUTION: Alerts the user to avoid or correct condi-

tions that could cause damage to or destroy equip-

ment.

NOTE: Identifies helpful procedures and information.

DISPENSE VALVE: Any fluid dispensing device that

can be triggered on and off.

Component Description

This equipment consists of two major components: the

air motor (1) and the displacement pump. See Fig. 1 .

The pump is an in-line design, which means that the

displacement pump screws directly into the motor,

without the use of tie rods or couplers. The displace-

ment pump can be placed directly in the fluid being

pumped.

The pump is available in three different lengths, based

on the size of the fluid container. Refer to the front cov-

er for available sizes. The pumps differ only in length;

operation and packings are the same. All three pumps

use Model 235887 Air Motor.

Make sure the muffler (36) is securely installed in the

exhaust port (N) before you operate the pump. See

Fig. 1.

CAUTION

Never run the pump without the muffler installed.

Mounting the Pump

1. Select a convenient location for the equipment, to

ensure easy operator access to the pump air

controls, sufficient room to change supply contain-

ers, and a secure mounting platform.

2. If using a follow plate (K), remove the fluid contain-

er cover. To prevent air from being trapped under

the follow plate, scoop grease from the center of

the container to the sides, to make the surface

concave. Place the follow plate on the grease and

push down on the plate until grease appears at the

center opening (P). See Fig 4.

around during operation. Failure to do so could

result in personal injury or equipment damage.

System Accessories

WARNING

Maximum Working Pressure

The maximum working pressure of each compo-

nent in your system may not be the same. To

reduce the risk of overpressurizing any part of your

system, be sure you know the maximum working

pressure rating of each component. Never exceed

the maximum working pressure of the lowest rated

component connected to a pump. Use the following

table to limit the air to the pump so that no air line

or fluid line component or accessory is overpres-

surized.

Installation

WARNING

A bleed-type master air valve is required in your

system to help reduce the risk of serious injury,

including splashing in the eyes or on the skin, and

injury from moving parts if you are adjusting or

repairing the pump.

The bleed-type master air valve relieves air trapped

between this valve and the pump after the air is

shut off. Trapped air can cause the pump to cycle

unexpectedly. Locate the valve close to the pump.

1. Install a bleed-type master air valve (B), to relieve

air trapped between the valve and the motor. See

the WARNING above).

2. Install an air regulator (C), to control the pump

speed and pressure.

3. Install an air line filter (F) to remove harmful dirt

and moisture from the compressed air supply.

4. Install a second bleed-type master air valve (G)

upstream from all other accessories, to isolate the

accessories for servicing.

5. Connect the fluid hose (L) to the dispense

valve (M). Use a gun holder (J) to hold the dis-

pense valve when not in use.

6. For ease in connecting the air line to the pump,

use an air line quick disconnect (E) at the pump air

inlet.

7. Connect the air (D) and fluid hoses (L) to the pump

(A). Use only grounded fluid and air hoses. Be

sure all hoses are properly sized and pressure-

rated for your system.

NOTE: Additional air line lubrication is not required to

extend the Eagletgrease pump air motor life. The air

motor is prelubed at the factory and should not require

additional lubrication between maintenance schedules.

No accessory air line lubricator should be installed.

Operation

Pressure Relief Procedure

WARNING

INJECTION HAZARD

Fluid under high pressure can be in-

jected through the skin and cause seri-

ous injury. To reduce the risk of an injury

from injection, splashing fluid, or moving parts, fol-

low the Pressure Relief Procedure whenever you

DAre instructed to relieve the pressure

DStop dispensing

DCheck or service any of the system equipment

DInstall or clean the spray tips/nozzles

1. Close the pump air regulator.

2. Close the bleed-type master air valve (required in

your system).

3. Hold a metal part of the dispensing valve firmly to

the side of a metal waste container, and trigger the

valve to relieve fluid pressure.

If you suspect that the spray tip or hose is completely

clogged, or that pressure has not been fully relieved

after following the steps above, very slowly loosen the

tip guard retaining nut or hose end coupling and relieve

pressure gradually, then loosen completely; then clear

the tip or hose.

Flushing

The pump is tested with lightweight oil, which is left in

to protect the pump parts. If the fluid you are using

may be contaminated by the oil, flush it out with a

compatible solvent before using the pump.

WARNING

For your safety, read the warning section

FIRE AND EXPLOSION HAZARD on

page 4 before flushing, and follow all

the recommendations given there.
