INLET PORT METERING CIRCUIT SSNS SSESSSS METERING PLUNGER PUMP CROSSHEAD INLET TUBE INLET STRAINER OPERATION CLEAR VUE PUMPING UNIT Model 25 Lubricators operate on a double plunger pump principle with a metering and a discharge plunger actuated through a yoke by an eccentric on the eccentric shaft The metering plunger controls the amount of lubricant fed to the discharge plunger This metered amount is adjusted by means of an external Feed Regulator Screw which adjusts the stroke length The lowermost position of the plunger is varied by the Feed Regulator Screw however the uppermost position to which the plunger rises remains constant On the downstroke the metering plunger draws lubricant up through the inlet tube over the inlet valves and into the metering pump cylinder On the upstroke the metering plunger seats its inlet valves and opens its spring loaded outlet valve forcing the metered amount of lubricant at low pressure out the drip tube into the Sight Chamber Well at atmospheric pressure On the same downstroke the discharge plunger opens the cross port to the Well and draws the metered amount of lubricant into the discharge pump cylinder This path is shown in light blue on the Assembly Drawing ak NY P las L51010 SIGHT CHAMBER WELL a ee ISS X 2 e SASSY AN D Ny Wl dan N VY eE anann IN W DISCHARGE PLUNGER AT TOP OF STROKE INLET PORT DISCHARGE2. 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 e General Purpose Lubrication automatic precision metering for all types of machinery e Pressures Up to 1000 psi e Type Pumping Unit Clear Vue Sight Feed Chamber functions at atmospheric pressure Shows amount of lubricant being pumped e Unitized Construction Contains complete feed regulating mechanism Equipped with inlet strainer e Number of Feeds 1 to 20 per Lubricator standard e Displacement Output 1 4 to 12 drops

CIRCUIT ECCENTRIC ON HEXAGON ECCENTRIC SHAFT RESERVOIR Finally on the upstroke the discharge plunger closes the cross port from the Sight Well and forces the metered amounts of lubricant over the discharge valves and into the line as shown in solid blue on the Assembly Drawing CLEAR VUE Sight Feed Chamber contains no sight feed fluid and functions at atmospheric pressure Molded glass sight cover and dust shield in various lengths for 1 to 8 pumping units Drip tube for each line indicates amount of lubricant fed each point of lubrication NOTE Due to design characteristics the Model 25 pump can only be used in pump to point system Components such as flow sensors and divider valves should not be used Only check valves are permitted between the pump and the lube point Page 2 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 is an extension of the eccentric shaft Th

9. e proper eccentric shaft RPM should be determined from the required maximum and minimum pump feed rates The RPM selected should be such that when each pump is set at its required feed rate the feed rate can still be increased or decreased by the feed regulator screw In most cases due to the wide adjustment of the pump units there will be considerable allowance in the selection of the proper eccentric shaft speed Note this eccentric shaft speed will seldom be the same as the Input shaft speed but will always be the same speed as the hand crank shaft extension The individual pumps operate on a double plunger principle with the metering and discharge plungers actuated through a yoke or crosshead by an eccentric on the eccentric shaft The small or metering plunger draws a metered amount of oil from the reservoir over the inlet ball valves and forces it over the outlet ball valve through the drip tube and into the clear vue sight well at atmospheric pressure The discharge plunger draws the metered amount of oil along with air from the sight well over the inlet sleeve valve and forces this mixture over the ball discharge valves toward the point of lubrication The stroke of the small metering plunger is varied to change the metered oil intake by means of the external feed regulator screw The stroke of the discharge plunger is constant IMPORTANT KEEP LUBRICATOR CLEAN First use only new or filtered lubricant Periodic cleaning of the Lubri
