Key Features
- Heavy-duty primary outer piston scaled and reinforced specifically for high-capacity H400S series pump footprints.
- Toughened alloy core handles elevated operating pressures and aggressive structural mechanical stroke loads firmly.
- Resists edge deformation, crushing, and material thinning under high continuous factory tightening torque fields.
- Spreads longitudinal shifting loads uniformly across the face perimeter to prevent premature diaphragm core fractures.
- Re-establishes original factory volumetric output metrics and stable continuous pipeline delivery cycles upon install.
