Guide Bush Assembly Kit G4 SP1120
The Guide Bush Assembly Kit G4 SP1120 is an essential component in Techni waterjet intensifier pumps, designed to guide and support the plunger during its high-pressure reciprocating motion. By maintaining precise alignment and reducing lateral movement, the guide bush minimizes friction and wear on both the plunger and cylinder liner, ensuring stable sealing performance and prolonging the service life of adjacent parts. Manufactured from durable, wear-resistant materials, this assembly plays a critical role in maintaining pump efficiency, cutting accuracy, and overall machine reliability.
