Take a Look Inside - We Think You'll Like What You see

Designed from the inside-out for longer lasting performance and reliability. G3 meets changing temperatures, challenging installation requirements and changing grease types head-on. Graco’s newest electric pump delivers high performance results in real world application conditions.

Advanced Flow Dynamics

Specially contoured base funnels grease directly to the pump inlet to significantly reduce stagnant flow areas where soaps and grease fillers can accumulate.

Adjustable Stroke Pump

With G3, adjustability comes standard! Eliminate the need to purchase additional fixed output elements or high-priced adjustable elements.

Load Minimizing Drive

Each G3 piston pump element is offset from the main motor shaft resulting in less stress on the motor and internal components.

Versatile, Hard-working Pump

Data Management System (DMS)
