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:
1 Do not exceed the pressure rating of any component in the system.
2 Protect all material and air supply lines from damage or puncture.
