The ULTIMATE LUBER™ is a powerful, motor-driven automatic lubricator which is refillable using standard grease guns. Its microprocessor controlled, energy efficient motor delivers grease to a fixed displacement pump which produces pressure up to 900 PSI. This strength allows the ULTIMATE LUBER™ to drive lubricant through long feed lines and to cycle progressive distributors to feed several bearings consecutively. When a dispensing cycle is selected, the units will activate at programmed intervals. At each interval, the ULTIMATE LUBER™ dispenses approximately 0.05 oz of grease. Neither temperature nor altitude will affect the lubricant outpout.
