Repair Kit - Kränzle Pump Seals

The Kränzle 12 mm pump seal repair kit is a service set designed to restore the tightness of the pump system. Used during maintenance and repairs of high-pressure pumps in 1050 series units when seal wear symptoms appear.

MPN / Reference: 49242
Weight: 0.090 kg
Dimensions / size (packaging): 10×1×10

APPLICATION

A component used in service work aimed at restoring pump tightness and proper operation, including:

• pump overhaul after prolonged use,
• устранение leaks in the pump section area,
• periodic inspections carried out in Kränzle equipment service centers,
• seal replacement after operation with contaminated water or frequent load cycles.

SYMPTOMS – WHEN IT’S WORTH REPLACING

Typical symptoms indicating pump seal wear:

• water leaks around the pump / head,
• drop in working pressure despite a functional nozzle,
• pressure pulsation or unstable pump operation,
• more frequent “topping up” of pressure and difficulty maintaining a steady jet,
• moisture/leak marks appearing after the unit has been standing.

HOW TO CHOOSE THE RIGHT PART

Selection should be precise, because even a small dimensional difference affects tightness and durability:

• by manufacturer MPN / reference: 49242,
• by size (12 mm): according to the kit description and the requirements of the specific pump,
• by comparison with the removed part: ideally compare old seals with the new ones before installation.

If you are unsure, the reference point should be the part number and parameters from the service documentation / parts list.

COMPATIBILITY

Kit intended for use in Kränzle 1050 series pumps (including variants commonly referenced in service practice, e.g. 1050P / 1050TS / 1050TST – always verify by MPN 49242 and pump parameters).
Selecting “by eye” based only on the machine name is not recommended — compatibility should be confirmed with the reference number and size.

[faq]

How can I be sure the kit will fit my pump?|The safest way is to select the part by MPN 49.242 and confirm that your application requires a 12 mm seal set. Additionally, compare the items with the seals removed during disassembly.
Can I choose the kit just because I have a Kränzle “1050”?|It’s a good starting point, but in service practice it’s crucial to confirm by the reference number and the pump’s technical data. Version/year differences may affect the seal set.
Can I use aftermarket seals instead of the original kit?|An aftermarket option can be considered only if it has identical dimensions and intended use, and is suitable for high-pressure systems. In practice, the most reliable criterion remains compliance with the MPN and specification.
