The 804020198 power unit is built with a high-strength cast iron housing that provides excellent rigidity and resistance to pressure spikes and mechanical shock. Critical internal components, such as the pump gears and bearings, are manufactured from hardened steel and coated with a wear-resistant layer to ensure long-term reliability. The housing is coated with a durable epoxy finish that resists corrosion, abrasion, and chemical attack from hydraulic fluids and environmental contaminants.
The power unit’s seals are manufactured from high-grade polyurethane and PTFE compounds, selected for their compatibility with all major hydraulic fluid types and resistance to thermal and chemical degradation. This ensures leak-free operation over the entire service life of the unit, even in high-pressure, high-temperature applications.
The 804020198 Power Unit is designed with multiple sealing elements that prevent internal and external leakage, ensuring that hydraulic energy is directed precisely where it is needed. The pump and valve sections are sealed with precision O-rings and backup rings that maintain their integrity under pressure cycling and temperature variations. The external ports are equipped with high-quality seals that provide a leak-tight connection to the hydraulic hoses and manifolds.
The unit features an integrated filtration system that removes contaminants from the circulating oil, protecting sensitive components from abrasive wear. A built-in bypass valve ensures that the filtration system remains effective even under cold-start conditions, preventing damage to the pump and valves. This comprehensive protection system extends the service life of the power unit and the entire hydraulic system.
The 804020198 power unit is compatible with a broad range of hydraulic fluids, including mineral oils, synthetic esters, and biodegradable fluids.
