Repair Kit - Kränzle Pump Seals

Kränzle 15 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 refurbishments and inspections when worn seals cause leaks or unstable operation of the high-pressure system.

MPN / reference: 42911
Weight: 0.060 kg
Dimensions / size (packaging): 10×1×10

APPLICATION

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

• replacing seals in the piston section / pump head area,
• eliminating water leaks in the pump section,
• pump refurbishment after long operation or after downtime,
• periodic inspections in pressure washers and industrial units equipped with an HP pump.

SYMPTOMS – WHEN IT’S WORTH REPLACING

Symptoms suggesting pump seal wear:

• water leaks around the pump or under the unit,
• drop in working pressure despite a functional nozzle and gun,
• jet pulsation, pressure fluctuations during operation,
• difficulty maintaining stable pressure under load,
• moisture/leak marks visible after downtime.

HOW TO CHOOSE THE RIGHT PART

Selection should be precise - seals must match the pump design and working size:

• by manufacturer MPN / reference: 42911,
• by size (15 mm): according to pump requirements and kit specification,
• by comparing with removed seals: check profile and dimensions before installation.

Accurate fit directly affects tightness, pressure stability, and pump service life.

COMPATIBILITY

This kit is described as intended for Kränzle 15 mm pumps, indicated for service use in K2195 and Quadro 9/170.
For safe selection, confirm compatibility by MPN 42911 and the pump’s technical data (table/specification). Selecting only by model name without reference verification is not recommended.

How do I confirm that kit 42911 fits my pump?|Check MPN 42911 in the parts list or documentation and confirm your pump uses the 15 mm seal version. Additionally, compare the parts with the seals removed during disassembly.
Do symptoms like pulsation and pressure drop always mean the seals are worn?|Often, but not always. Similar symptoms can be caused by the nozzle, valves, or air ingress. However, if you see leaks around the pump or moisture marks, seals are among the first components to check.
Can I use an aftermarket seal set instead of a Kränzle kit?|Only if the alternative has identical dimensions, profile, and intended use for high-pressure systems. Incorrect selection usually results in leaks and rapid wear - therefore, the MPN and pump technical data should be your reference point.
