Sealing Head SP-71-9

The Sealing Head SP-71-9 is a critical component in a Techni waterjet machine’s intensifier pump assembly. It houses and supports the sealing elements (such as high-pressure seals and O-rings) that prevent water or hydraulic fluid leakage under extreme pressure. Positioned between the pump’s plunger or piston and the cylinder body, the sealing head ensures a tight, reliable barrier when the intensifier generates the high-pressure pulse required for cutting. Its material—usually high-grade, wear-resistant steel or similar alloy—and precision manufacturing are essential: any imperfection can lead to seal failure, loss of pressure, water ingress, or premature wear. Replacing or servicing the Sealing Head SP-71-9 at the proper intervals helps maintain cutting efficiency, safety, and long machine life.
