Stay ahead of the competition with LD Series Pumps. These affordable and full featured pumps are designed for lower volume applications. These pumps are fine-tuned for a compact, flexible and still incredibly durable solution.
Features
- Three Inch Air Motor - Provides more power to create better flow
- Innovative 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
- Engineered for Durability - Patent-pending cup and plate design eliminates the need for O-rings that wear out faster for a more durable, longer-lasting solution
- Modular Air Valve - Air inlet and exhaust locations are easy to configure with just four bolts for simple, hassle free installations
- Pilot Valve - Patent-pending, self-cleaning design increases reliability in dirty air environments and minimizes pressure drop with rapid changeovers for reduced stalling and smoother flow
- Adjustable Bung Adapter Included - Built-in slide adjustment with easy-set hand screws can fit into more applications
- 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
