Graco Electric Dyna-Star Pump for Reliable Automatic Lubrication
Description
The Graco Electric Dyna-Star HP and HF 24VDC lubrication pumps are designed for heavy-duty mining, construction, and industrial equipment that requires reliable automatic lubrication under demanding operating conditions.
The Electric Dyna-Star lubrication pump delivers consistent grease supply without relying on compressed air, helping improve reliability, reduce maintenance challenges, and support continuous equipment protection.
It complements the Graco hydraulic and Fire-Ball pneumatic lubrication pump range, giving operators multiple power source options for automatic lubrication and fluid transfer applications.
Electric Automatic Lubrication Pump for Heavy-Duty Equipment
The Electric Dyna-Star pump is designed to maintain continuous lubrication on critical machine pivot points, helping flush contaminants and reduce wear.
It is commonly used where consistent lubrication delivery is essential for machine uptime and component life.
Typical applications include:
- Oil Transfer
- Grease Transfer
- Off-road Lubrication
- Series Progressive Lubrication
- Single Line Parallel Lubrication
- Single Line Resistive Lubrication
- Spray Lubrication
Features of the Electric Dyna-Star Lubrication Pump
- Auto Fill Shut Off – mechanical shut off of fill pump for a clean and efficient refill.
- Graco Advantage Drive™ system with heavy duty gear drive-lubed for life.
- Tube-in-tube vent and fill path–convert drum to injector system instantly.
- Vent valve mounted directly to pump–no more brackets or extra hoses and pipes.
- Motor control–speed and AMP control.
- Cold weather performance (-40º C).
- More efficient seal replacement.
- Optional AC to DC Power Converter Box.
- Enables the use of 110 to 230 VAC power to run the 24 VDC Dyna-Star HP and HP pumps.
- AC to DC Converter box comes with mounting and wiring hardware making installations easy and flexible.
- Remote Fill Manifold with Vent (with built-in pressure gauge) allows you to conveniently locate the fill port where you want it.
These features are designed to improve system reliability while simplifying installation and servicing in the field.
Pump Variants: – HP and HF Models
The Electric Dyna-Star range includes both HP and HF models, allowing selection based on pressure and application requirements.
HF Models
- Maximum working pressure: 241 bar (24.1 MPa)
HP Models
- Maximum working pressure: 344 bar (34.47 MPa)
Both versions are designed for demanding lubrication environments where system consistency and durability are critical.
