Graco Manzel Model 25 Lubricator- User Manual

DESCRIPTION

Manzel Model 25 Force Feed Lubricators are economical, general-
purpose units of double plunger design for precise metering of
lubricants (either mineral oil base or synthetics). They provide
lubrication to cylinder walls, bearings and other moving parts
of equipment such as sugar mills, steam engines, presses and
general machinery. They are furnished with Clear-Vue Pumping
Units whose sight feeds, operating at atmospheric pressure,
show the output of lubricant to individual points of lubrication. All
working parts are totally enclosed—away from dust, water and
impurities—and self-lubricated at all times by the lubricant in
the reservoir. Standard Lubricators may be had in 1 to 20 feeds
for feeding the same type of lubricant. A choice of Drives and
Mounting Arrangements facilitates designing Lubricators into
Original Equipment or installation on existing machinery. These
can be driven from rotating or reciprocating parts of machines or
engines or by independent motors.
