Repair Kit - Kränzle Pump Seals

Kränzle 14 mm pump seal repair kit is a service set designed to restore tightness and stable operation of a high-pressure pump. It is used during repairs and inspections when worn seals cause leaks or reduced performance.

MPN / reference: 41.649-1
Weight: 0.060 kg
Dimensions / size (packaging): 10×1×10

APPLICATION

The kit is used in Kränzle pump service work, especially for:

• refurbishing the pump sealing section (wet work around the head),
• replacing seals after prolonged use or after downtime,
• eliminating leaks that affect pressure stability,
• periodic inspections carried out in pressure washer service centers.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Typical symptoms indicating seal replacement is needed:

• water leaks around the pump or pump-section connections,
• drop in working pressure despite functional accessories,
• jet pulsation and pressure fluctuations during operation,
• difficulty maintaining constant pressure under load,
• moisture/leak marks visible after the unit has been standing.

HOW TO CHOOSE THE RIGHT PART

Accurate fit is critical for pump tightness and service life:

• by manufacturer MPN / reference: 41.649-1,
• by size (14 mm): according to pump requirements and the kit specification,
• by comparison with removed parts: check the profile and dimensions before installation.

If in doubt, base the selection on the part number from the documentation or service parts list.

COMPATIBILITY

Kit intended for service use in Kränzle pumps described as 14 mm, specified for K-205T.
For safe selection, confirm compatibility by MPN 41.649-1 and the pump’s technical data (table/specification), rather than assuming based on the machine name alone.

How can I be sure kit 41.649-1 fits my pump?|The most reliable criterion is matching MPN 41.649-1 and confirming that the pump uses a 14 mm seal set. Additionally, compare the parts with the seals removed during disassembly.
Is 14 mm size enough to select the seals?|Size matters, but it does not replace verification by the manufacturer reference. Variants can exist within one pump family, so it’s best to confirm selection by MPN and specification.
Can I use an aftermarket set instead of the original Kränzle kit?|Only if the alternative has identical dimensions and intended use and is rated for high-pressure systems. A loose fit or different seal profile usually results in leaks and faster wear - therefore, the MPN and technical data should be the reference point.
