Installation

Mounting

Reservoirs have end mounting lugs as shown in outline

drawings on page 9. Use all mount features provided to

ensure the lubricator is rigidly fixed after installation.

Select a mounting location that will accomplish the fol-

lowing goals:

• Allow easy access to the lubricator for filling the

reservoir and periodic maintenance.

• Provide a stable surface upon which the lubrica-

tor can operate.

• The lubricator must be connected to a ground

source.

Drive Mechanism

A 5/8 in. diameter shaft is provided to connect the lubri-

cator to a rotary power source. A number 5 woodruff key

and key way on the shaft are provided to aid in connect-

ing this source.

Install protective guards around all drive components

upon installation.

System Connections

It is recommended that each pumping unit be installed

with a check valve in the discharge line so that the pump

assembly may be removed from the reservoir without

loss of lubricant in the discharge lines. The installation of

a second check valve at the end of the discharge line

will prevent line drainage and act as a positive means of

avoiding feedback of system pressure to pump.

When using Model 88 pumps, torque the union fitting on

the outlet check valve to 37- 42 ft-lb (50-57 N•m)

Lubricant Types and Viscosities

Graco Modular Box Lubricators are suitable for use with

mineral oil or synthetic base lubricants with viscosities in

the range of 100 to 5000 SUS under pumping condi-

tions.

CAUTION

The installation and all work concerning assembly,

maintenance, and repair must be completed by qual-

ified personnel.

When possible, mount the lubricator on a surface

that experiences little to no vibration.

CAUTION

The recommended speed of the mechanism driving

the lubricator is 3 - 50 rpm. Do not exceed the maxi-

mum value of 50 rpm to avoid pump damage.
