Guide Bush Assembly, 19 mm | G4 | HJ-SP1124
The HJ Waterjet HJ-SP1124 Guide Bush Assembly, 19 mm is a precision-engineered replacement component designed for Techni Generation 4 waterjet intensifier pump systems. Also identified by Techni part number SP1124, this guide bush assembly is an important component within the pump cylinder and plunger assembly, providing accurate guidance and support for the reciprocating plunger during high-pressure pump operation.
The 19 mm guide bush helps maintain proper plunger alignment, controlled movement, and dimensional stability inside the pump assembly. Proper guidance is essential for minimizing unwanted movement and reducing friction between the plunger and surrounding components. Maintaining correct alignment can also help protect associated sealing components, cylinder components, and other wear surfaces from premature deterioration.
The HJ-SP1124 Guide Bush Assembly is intended for waterjet pump maintenance, repair, rebuilding, and overhaul applications where worn or damaged guide components need to be replaced. Replacing a worn guide bush can help restore proper plunger support and contribute to reliable high-pressure waterjet pump operation.

Application
The HJ-SP1124 Guide Bush Assembly is used in the Techni G4 intensifier pump assembly. The guide bush works in conjunction with the plunger, seal housing, wiper seals, high-pressure seals, cylinder liner, and other pump components to maintain proper alignment and controlled movement of the reciprocating plunger.
The HJ-SP1124 Guide Bush Assembly is particularly important when servicing a pump that exhibits signs of guide-component wear, excessive plunger movement, leakage, accelerated seal wear, or reduced operating reliability.
Why Replace a Worn Guide Bush?
A worn guide bush can contribute to improper plunger alignment and increased mechanical movement inside the pump assembly. Continued operation with worn internal components may accelerate wear on related seals and cylinder components.
During a waterjet pump rebuild or preventive-maintenance service, inspecting the guide bush and replacing it when necessary, can help restore the correct relationship between the plunger and surrounding pump components.
