Master Pneumatic – 74 and 77 Liquid Dispensers

The Series 740 liquid dispenser employs Servo-Meters to send precise amounts of liquid through nozzles for a distance up to 10 inches (250 mm). It is primarily used where liquid without entrained air is wanted, and a precisely controlled jet is not required.

Up to 10 Servo-Meters can be used in a single assembly. A pressure of at least 60 psig (4 bar) is required for actuation.

1/8-Inch O.D. nylon tubing carries the oil from a Servo-Meter to a nozzle [5/64” (2-mm) orifice] located near the delivery point.

Install a liquid-only dispenser so that the Servo-Meters are vertical and the outlets are at the top. This helps to eliminate air from the system. The nozzles need to be secured in place with a clamp or similar means.

Series 740 factory assemblies employ two mounting holes. When a very rigid mounting is needed, order Series 770 which employs heavy-duty mounting plates with four mounting holes.
