Low Pressure Fluid Lubricant Pumps

7783-C4

DESCRIPTION

Model 7783 Series Pumps are single-action, low pressure units de-
signed to deliver fluid lubricants from original containers or bulk 
tanks.

The differences in the pumps are that model 7783-A4 is used with 
55-gallon drums , model 7783-B4 is used with 16-gallon drums and 
model 7783-C4 is a stub pump and can be used with extensions .

All models produce a 6:1 material-to-air pressure ratio. The maximum 
operating air pressure of 200 psi would,therefore, create a maximum 
material pressure of 1200 psi.

The pumps are capable of supplying a high volume of lubricant at a 
low rate of speed (e.g.-At 100 psi air pressure,the pump delivers 10 
gallons of SAE No. 140 gear oil per minute).

NOTE:

 The air motor (323440-4) is packed with lubricant at the fac-

tory and should require no additional lubrication

.

GENERAL SAFETY REQUIREMENTS

Because these units are incorporated into pressure pumping systems, 
it is good practice to observe and use the following safety precautions:

Do not exceed the pressure rating of any component in the system.

Protect all material and air supply lines from damage or puncture.
