The Multiquip EM50442 Nozzle is a genuine OEM component designed for QP3TZ and QP2TZ series trash pumps. As a direct OEM replacement, it meets the original design and material specifications set by Multiquip, ensuring the part seats and functions exactly as intended in these Hatz diesel-powered quick-prime units. Whether you are performing scheduled maintenance or replacing a failed nozzle, part number EM50442 is the correct factory-sourced solution for QP3TZ and QP2TZ pumps.
Key Features
- Genuine OEM Fuel Delivery Precision — Manufactured to the exact orifice and flow specifications required by QP3TZ and QP2TZ engines, ensuring the correct fuel atomization pattern that aftermarket nozzles may not replicate.
- Drop-In Installation — Engineered to the original mounting interface, so the EM50442 installs directly into the existing nozzle seat without reworking fittings or adapters.
- Confirmed Fitment for QP3TZ and QP2TZ — Verified OEM replacement for both Multiquip quick-prime Hatz-powered trash pump models, eliminating guesswork when ordering.
- Consistent Engine Start and Run Quality — A correctly functioning nozzle delivers a clean, metered fuel spray that supports reliable cold starts and smooth engine operation under pump load; a worn or clogged nozzle causes hard starting, rough running, and loss of prime.
- Fuel System Integrity — Using the OEM-spec nozzle maintains proper injection pressure and spray pattern, protecting downstream engine components from the effects of incorrect fuel delivery.
The nozzle is a precision fuel-injection component responsible for atomizing diesel fuel into a fine, controlled spray before it enters the combustion chamber. A properly functioning nozzle ensures complete fuel burn, stable engine power output, and efficient pump operation. When a nozzle wears, clogs, or develops a distorted spray pattern, the engine may exhibit hard starting, increased fuel consumption, black exhaust smoke, or an inability to maintain the output pressure needed to move water and solids through the pump.
