Repair Kit - Kränzle Pump Valves

The Kränzle Junior 120 pump valve repair kit is a set of service parts intended for refurbishing the valve section of a high-pressure pump. Replacing valves is a typical corrective action when the pump cannot hold pressure, runs unevenly, or loses output.

MPN / reference: 43.096
Weight: 0.15 kg
Dimensions / size (packaging): 10×1×10

APPLICATION

Used in service work on pressure washer pumps, including:

• replacing suction and discharge valves in the pump valve section,
• fixing issues related to pressure loss and unstable pump operation,
• repairs after operation with contaminated water (deposits and sand reduce valve sealing),
• periodic inspections in older units where valve wear is a common cause of reduced performance.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Typical symptoms of worn pump valves:

• noticeable drop in working pressure and output,
• jet pulsation and pressure fluctuations during operation,
• difficulty maintaining stable parameters under load,
• unstable pump behavior after releasing the trigger (pressure rollback/“floating”),
• signs of leakage in the pump section after ruling out accessories (nozzle, gun, water filter).

HOW TO CHOOSE THE RIGHT PART

Valve selection must match the pump design and valve seats:

• by manufacturer MPN / reference: 43.096,
• by application: Kränzle Junior 120,
• by comparison with removed parts: verify valve type, dimensions, and how they seat in the valve ports.

Accurate fit is critical for valve-section tightness and restoring stable pump parameters.

COMPATIBILITY

Kit described as intended for the pump used in Kränzle Junior 120 units.
For safe selection, confirm compatibility by MPN 43.096 and the pump documentation/parts list (table/specification). Older units may have production variants, so reference verification is the most reliable method.

Will replacing valves fix pressure drop in a Junior 120?|Often yes, if valves are leaking or worn. Similar symptoms can also be caused by the nozzle, water filter, air ingress, or an unloader/regulating valve — it’s worth ruling these out before opening the pump.
How do I confirm kit 43.096 fits my pump?|The safest method is checking MPN 43.096 in the Junior 120 parts list and comparing removed valves with the new ones (type, dimensions, seating method).
Can I use aftermarket valve replacements instead of the Kränzle kit?|Only if type, dimensions, and intended use match exactly. Valves must seal properly on their seats; an incorrect match leads to pulsation and reduced output, so use the MPN and pump technical data as your reference point.
