Stay ahead of the pack with the LD series pumps.
These affordable and full featured pumps are designed for lower volume applications and are available to suit 20kg, 55kg, 180kg High pressure, medium flow for cold temperature or long run applications
Maximum Fluid Working Pressure 750 psi
- 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.
