Interpump Seal Kit 69 (WS/WX Series)

Overview

The Interpump Seal Kit 69 is a complete OEM seal pack for select WS‑series pumps that use the “69” seal stack. It restores pump efficiency by replacing high-wear sealing components in the water end.

Kit Contents (typical)

• High-pressure seals (HP seals)
• Low-pressure seals (LP seals)
• Support rings/back‑up rings and associated o‑rings

When to Use

• Visible leakage from the manifold weep ports
• Reduced performance due to bypass, excessive heat, or abrasion wear
• Scheduled preventative maintenance

Fitment Guidance

Compatible with WS/WX pumps that specify Seal Kit “69”. Always confirm using your pump nameplate code or the service manual before ordering.

Installation Notes

• Clean the manifold and plunger surfaces thoroughly; inspect plungers for scoring.
• Lubricate seals lightly with pump oil during assembly and observe orientation.
• Pressure test after reassembly and check for leaks at operating temperature.

Maintenance

Maintain adequate inlet filtration and water quality to maximize seal life. Avoid running dry or in cavitation.
