Spacer Tube 1-11521 Waterjet Pump Parts From China

The Spacer Tube 1-11521 is an important structural spacing and alignment component used in Waterjet Intensifier pump systems. Its main function is to maintain correct spacing between internal components, ensuring proper assembly alignment, stable load distribution, and reliable operation under high-pressure conditions.
This spacer tube is commonly installed between key mechanical parts such as cylinders, retainers, or support structures. It helps prevent direct metal-to-metal contact, reduces uneven stress, and supports accurate positioning of the intensifier assembly during continuous operation.
A high-quality spacer tube is essential for maintaining structural stability, reducing mechanical wear, and ensuring long-term pump reliability.

Is Spacer Tube 1-11521 a Wear Part?

Yes — the Spacer Tube 1-11521 is considered a semi-wear part.
Although it does not directly handle high-pressure fluid flow, it is continuously subjected to mechanical stress, vibration, clamping force, and repeated maintenance cycles. Over time, it may experience deformation, wear, corrosion, or dimensional inaccuracy.
If not replaced when damaged, it can lead to misalignment, uneven load distribution, and accelerated wear of surrounding components.
Regular inspection during maintenance is strongly recommended.
