Repair Kit - Kränzle Pump Seals

Kränzle 14 mm pump seal repair kit is a service set designed to restore tightness of the pump section in high-pressure pumps. It is used during refurbishment when worn seals cause leaks, unstable pressure, or reduced performance of the high-pressure system.

MPN / reference: 49053
Weight: 0.060 kg
Dimensions / size (packaging): 10×1×10

APPLICATION

The kit is used for typical Kränzle pump service work, including:

• replacing seals in the piston / sealing section area,
• eliminating water leaks around the pump head,
• periodic inspections and refurbishments carried out in high-pressure equipment service centers,
• repairs after intensive use (long duty cycles, frequent start/stop).

SYMPTOMS - WHEN IT’S WORTH REPLACING

Most common signs of pump seal wear:

• water leakage around the pump or from under the housing,
• drop in working pressure despite a correct nozzle and gun,
• jet pulsation / pressure fluctuations during operation,
• difficulty maintaining stable pressure under load,
• moisture on pump components after downtime or after finishing work.

HOW TO CHOOSE THE RIGHT PART

To avoid leaks and accelerated wear, selection should be done accurately:

• by manufacturer MPN / reference: 49053,
• by size (14 mm): according to the requirements of your pump and the kit specification,
• by comparing with removed seals: check shape and dimensions before installation.

In service practice, the reference number is the safest criterion because it prevents mix-ups between pump variants.

COMPATIBILITY

This kit is described as intended for Kränzle 14 mm pumps used in systems labeled AZ and K1152. In service practice, it is often associated with units such as HD 10/122, HD 10/122 TS, HD 7/122, HD 7/122 TS, K 1132, K 1152 TS, K 1152 TST - however, final selection should be confirmed by MPN 49053 and the pump’s technical data (table/specification), rather than relying only on the model name.

[faq]

How do I check if kit 49053 fits my unit?|Verify MPN 49053 in the documentation/parts list and confirm that your pump uses a 14 mm seal set. Additionally, compare the parts with the seals removed during disassembly.

Can I choose the kit only based on a model list (e.g., HD 10/122 TS or K 1152 TST)?|The model list helps narrow it down, but in service practice the key is confirming by reference number and pump parameters. Manufacturing variants may use different seal sets.

Can I use an aftermarket seal set instead of the original kit?|Only if the alternative has identical dimensions and intended use and is rated for high-pressure systems. The biggest risks are leaks and rapid wear - therefore, the safest reference point is the MPN and specification.
