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.

FEATURES/BENEFITS

General-Purpose Lubrication: • automatic, precision

metering for all types of machinery.

Pressures:• Up to 1000 psi

Type Pumping Unit:• Clear-Vue. Sight Feed Chamber

functions at atmospheric pressure. Shows amount of

lubricant being pumped.

Unitized Construction:• Contains complete feed regulating

mechanism. Equipped with inlet strainer.

Number of Feeds:• 1 to 20 per Lubricator, standard.

Displacement, Output:• 1/4 to 12 drops per stroke with 5/16

in plunger; 1/6 to 6 drops per stroke with 3/16 in plunger.

Available Drives:• Direct Rotary (1:1), Ratchet, 37.5:1 and

75:1 internal gear reductions.

Reservoirs:• Single Compartment, sheet metal construction.

Feed Regulator:• External screw-type precisely adjustable

while idle or in operation.

Removable Pumping Unit:• Self contained. All units

interchangeable - remove two pump screws and lift out.

Hand Crank:• Standard. Convenient for rapid priming of

lines before start-up or for momentarily increasing supply of

lubricant. Does not affect adjustment or individual pumping

units. Replaces obsolete Kipp Model 50 Box Lubricators.

Manzel® Model 25 Lubricator™ L51010 OPERATING INSTRUCTIONS LUBRICATOR INSTALLATION AND OPERATION – The Manzel Model 25 Lubricator consists of a metal reservoir which contains the drive mechanism, ratchet or rotary, the individual pump units and accessory equipment as ordered. The Lubricator should be solidly mounted and aligned to connect the drive shaft to the proper stroking or rotary motion.

Manzel® Model 25 Lubricator™ L51010 MODEL 25 PUMP SPECIFICATIONS DRIVES DIRECT ROTARY – (1:1) Shaft located either or both ends. STANDARD RATCHET – (See Graph for drive ratio per degree stroke.) Two variations available: (a) Shaft located either end. The drive reduction ratio depends on the degree stroke taken on the input shaft from a minimum of 13° for a 37-1/2:1 ratio to a maximum of 90° for a 4-1/6:1 ratio. (b) Shaft located front or rear.
