Prietoková dýza čerpadla 1,8mm

The 1.8 mm pump flow nozzle is a component of the washer’s internal flow system, used in the pump assembly to control/restrict flow according to the system design. In service practice, the nozzle is replaced when clogging is suspected, when the working orifice is damaged, or when operating parameters deviate from normal despite the main components being in good condition.

MPN / reference: 13225
Orifice diameter: 1.8 mm

APPLICATION

The flow nozzle is used in typical pump-system service work:

• maintaining correct flow conditions in the pump subassembly,
• repairing flow disturbances caused by dirt or deposits,
• rebuilding flow-related components during pump overhaul,
• replacing the nozzle after mechanical damage or improper prior intervention.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Consider replacing the nozzle when you notice:

• unstable system behavior caused by flow disturbances,
• reduced operating parameters after ruling out the working spray nozzle/accessories,
• symptoms of partial clogging (variable operation, fluctuations),
• orifice damage (out-of-calibration enlargement or deformation),
• deposits/contamination that can’t be reliably removed without replacement.

HOW TO CHOOSE THE RIGHT PART

Selection should be unambiguous:

• verify the 1.8 mm orifice diameter,
• confirm the manufacturer number: MPN 13225,
• compare with the removed part: seating method, length, and geometry,
• base selection on the pump subassembly service documentation.

For flow nozzles, orifice diameter is critical-changes by fractions of a millimeter can alter system operating conditions.

COMPATIBILITY

Select the nozzle based on MPN 13225 and the 1.8 mm parameter, according to pump service documentation. Don’t choose a nozzle “by diameter only” without confirming the part number and seating type, because similar nozzles can differ in design.

[faq]

Is the 1.8 mm flow nozzle the same as the spray nozzle on the lance?|No. The flow nozzle works inside the pump system to control flow conditions. The spray nozzle is an end accessory component that shapes the washing jet.

What contaminants most often clog flow nozzles?|Most commonly fine sand, scale, and debris from the water supply. That’s why inlet filtration and clean water supply directly affect nozzle life.

Will using a larger diameter than 1.8 mm “improve flow” and fix the issue?|You shouldn’t do that. Changing diameter alters the system characteristics and can cause improper pump or control behavior. Use the nozzle specified for the system.

How do I know the flow nozzle is the issue and not the filter or inlet hose?|First rule out simple causes: inlet filter, water supply, and accessories. If those are OK and flow symptoms remain, then it makes sense to inspect internal components such as the flow nozzle.

What should I check after replacing the flow nozzle?|System stability, absence of parameter fluctuations, and cleanliness of the water supply/filters. If contamination was the cause, remove the source so the new nozzle doesn’t clog again.
