Manzel Model 25 Lubricator ® DESCRIPTION Manzel Model 25 Force Feed Lubricators are economical, generalpurpose 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. General-Purpose Lubrication: automatic, precision metering for all types of machinery. 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. Heavy-gauge fabrication sheet steel Cast iron Hardened stainless steel balls Sintered metal, single throw on hexagon eccentric shaft Gaskets, Seals Standard for mineral oil base lubricants. Special materials available for synthetics 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. Round with vents and strainer Removable Pumping Unit: Self contained. All units interchangeable - remove two pump screws and lift out. Discharge Check Valve Double ball discharge check valve assembly with 1/4 in NPSF vertical outlet 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. All ferrous metal drive parts Parco-Lubrited. Reservoir exterior, cover and pumps painted with durable hammertone gray finish. Nickel plate, available.

Manzel® Model 25 Lubricator™ 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. This drive motion, through the Lubricator drive, should operate the Lubricator eccentric and hand crank shaft between 3 and 60 RPM. There is one pump stroke for every revolution of the hand crank shaft, which...

Where additional feeds are required, contact factory. ® All displacements based on SAE30 Oil (SSU @ 100°F) at room temperature. A The capacities of reservoirs are originally determined by the number of feeds. Larger ones available on request. * Special sight glass and gasket materials required. All surfaces in contact with lubricant must be free of paint. * Manzel Lube Line Alert or Lube Sentry should not be used with the Model 25 Box Lubricator. Contact factory for complete details.
