Alemite Grease Pump

Alemite Grease Pumps: A Century of Lubrication Expertise

When it comes to moving grease precisely, reliably, and at high pressure, few names carry more weight than Alemite. Since 1918, Alemite has been supplying quality lubrication systems and equipment to meet the needs of numerous industries. That long track record is not incidental — Alemite pioneered innovations such as the high-pressure lubricating system, transforming routine maintenance tasks into efficient processes. Their grease pumps represent one of the most refined expressions of that engineering heritage.

What Sets Alemite Grease Pumps Apart

Alemite grease pumps are designed to handle a wide range of applications, fluid viscosities, and system pressures. Whether you're running a small automotive service bay or a large-scale industrial maintenance operation, there is an Alemite pump configuration built for the task. Available in portable and stationary configurations, pump ratios range from 26:1 to 70:1 — giving technicians the flexibility to match output pressure to the specific demands of the job at hand.

Alemite's grease pump lineup includes several notable series and models engineered for distinct scenarios:

• RAM Series (Stationary): Designed for manufacturing plants, centralized lubrication systems, and high-volume maintenance facilities with fixed piped installations, these pumps feature a dynamic primer system that handles light to heavy greases efficiently, and self-aligning heavy ACME threads to reduce binding and extend service life.
• Portable Air-Operated Models: High-pressure 50:1 ratio pumps are designed to deliver a range of greases up to NLGI #3 and operate directly from their original 120-pound container. The popular 9951-T1, for example, is built around a hand truck for mobility in field service environments.
• Industrial Pneumatic Drum Pumps: Tote tank pump models include a male 3" Cam Lock Adapter for mounting the pump directly to a bulk grease container, making them ideal for high-volume shops and service fleets.

Engineering Features That Matter in the Field

Across the lineup, Alemite builds meaningful serviceability and durability into each pump. The orientation of the material outlet and air inlet can be easily adjusted 360 degrees, pumps are designed to operate with or without a lubricator, and the air motor and spool valve are easily accessible without removing the downtube. A flexible follower works with both straight and tapered containers, reducing downtime when switching between drum types on the floor.

OSHA noise compliance (at or below 85 dB) is built into the air motor design, an important consideration for shop floor environments with strict safety regulations. Compatible grease types span multi-purpose EP greases, lithium complex, calcium complex, aluminum complex, synthetic lubricants, heavy gear oils, and fibrous greases — covering virtually any lubrication specification a maintenance professional might encounter.

Versatility Across Industries

Alemite products are used in manufacturing, construction, agriculture, automotive, pulp and paper, aircraft maintenance, marine, and mining industries, providing maximum efficiency, productivity, and reliability. Alemite grease pumps are designed to handle a wide range of applications, fluid viscosities, and system pressures — and combined with other Alemite products such as hose reels, dispensing valves, and automatic lubrication devices, they can deliver lubricants from pails, drums, tanks, and totes.

For professionals who depend on their equipment day in and day out, an Alemite grease pump is a long-term investment backed by over a century of lubrication engineering. Explore the full Alemite brand catalog or browse all grease pumps to find the right solution for your application.
