GRACO 224752 – Hydraulic Dyna-Star 5 1 Grease Pump, 400 lb Drum, 7500 PSI

GRACO 224752 – Hydraulic Dyna-Star 5:1 Grease Pump, 400 lb Drum, 7500 PSI

Hydraulic Dyna-Star pumps provide reliable, quiet, ice-free performance at maximum pressure and low-flow rates and are up to three times more energy efficient than comparable compressed-air systems.

Built-In Reliability – Self-lubricating vertical design for long life and reliable operation in high-vibration environments.

Quiet Hydraulic Motor – No need for add-on mufflers.

High-Efficiency Motor – Uses less hydraulic oil.
