Industrial Hydraulic Technology

Heavy-Duty Hydraulic Power Built for Tough Industrial Coatings

Equipped with a robust hydraulic piston system and a USA Haas CNC-machined fluid pump, delivering a massive 12.0 L/min fluid displacement at 3000 PSI and utilizing Heavy-Duty UPE & Leather V-Packings to effortlessly atomize high-viscosity protective coatings for continuous industrial output.

High-Capacity Thermal Stability

Faster Cooling & No Downtime

The high-capacity cooling system’s innovative design allows the pump to run cooler and more efficiently during heavy-duty continuous operation. This thermal stability ensures a sustained 3000 PSI (20 MPa) to eliminate costly downtime without thermal shutdown. Built-to-last equipment goes through stringent quality checks to ensure compliance with EN ISO 12100:2010 so high-quality standards are met.

Severe-Duty Immersion Pump

Unrestricted High-Viscosity Flow

The direct immersion pump with a submerged foot valve easily loads and pumps high-viscosity fluids like heavy mastics, putty, and bitumen. It features Tungsten Carbide valves and Heavy-Duty UPE & Leather V-Packings for ultimate durability with most materials. With a 12.0 L/min maximum flow rate, the oversized passages and a 0.051″ tip provide maximum flow and superior atomization.

Reliable Heavy-Duty Drive

MAXIMUM POWER TRANSFER

A 9.0 HP gas engine with an integrated fuel tank delivers maximum performance, making it adaptable to any jobsite. For indoor and outdoor use, quickly swap the gas engine for a 4000W electric motor in seconds without tools. Every sprayer is factory tested with a 30-minute high-pressure load test, and the field-proven design keeps the sprayers performing with factory reliability on the job for years.
