Stay ahead of the competition with LD Series Pumps. These affordable and full featured pumps are designed for lower volume applications and are available in 3:1 and 5:1 for oil and 50:1 for grease. These pumps are fine-tuned for a compact, flexible and still incredibly durable solution.

LD Series Oil Pump

You work hard to provide good service and that’s exactly what we had in mind when we engineered the LD Series Packages. Whether your delivery is in your backyard or 50 miles away, LD Packages reliably do the job. You can count on Graco equipment to reduce repair hours so you can concentrate on deliveries and bring more to your bottom line. 

All LD package  meters come standard  with trigger guard, hose boot and automatic nozzel.

  • Three Inch Air Motor – Provides more power to create better flow.
  • NXT Air Valve – Designed to reduce icing in continuous use applications and uses less air than competitive pumps for better efficiency. Easy to repair or replace without tearing down internal pump components for less downtime.
  • Modular Air Valve – Air inlet and exhaust locations are easy to configure with just four bolts for simple, hassle free installations.
  • Built-In Thermal Relief and Inlet Strainer – Built-in thermal relief protects your equipment from thermal expansion without the need to buy and install an additional kit. Inlet strainer (oil only) is built-in to protect pump from containments that can damage your pump.
