The Multiquip 01322200 Injection Pump is a genuine OEM component designed for QP3TZ and QP2TZ series trash pumps. As a direct OEM replacement, this injection pump is sourced from Multiquip to meet the same specifications as the original unit installed at the factory. Verified fitment for the QP3TZ and QP2TZ ensures this pump seats and connects exactly as the original did, with no guesswork on compatibility. When your trash pump starts showing signs of hard starting, poor fuel delivery, or inconsistent engine output, the 01322200 is the correct OEM solution to restore full operation.
Key Features
- OEM Fuel Metering Accuracy — Genuine Multiquip part engineered to deliver the correct fuel volume and timing for consistent engine combustion in Hatz-diesel-powered trash pump applications.
- Direct-Fit Replacement — Mounts to the same connection points as the original injection pump, allowing a straightforward swap without adapters or modifications to fuel lines or mounting hardware.
- Confirmed Fitment for QP3TZ and QP2TZ — Verified compatibility with the QP3TZ and QP2TZ Hatz-diesel trash pumps, so you can order with confidence.
- Restores Full Engine Output — A worn or failed injection pump causes hard starts, uneven power, and reduced pumping capacity; replacing it with part 01322200 returns the engine to its rated output.
- Fuel System Integrity — Correct injection pump function is critical to safe diesel engine operation; using a genuine OEM unit ensures fuel delivery pressure and timing remain within the designed operating range.
The injection pump is the heart of a diesel fuel system — it draws fuel from the tank, pressurizes it, and delivers precisely metered charges to the injector at the right moment in the engine's cycle. On the QP3TZ and QP2TZ trash pumps, a properly functioning injection pump is what allows the engine to start reliably and sustain the power needed to move high volumes of debris-laden water. When the injection pump wears out or fails, fuel delivery becomes erratic, leading to rough running, loss of pumping performance, or an engine that won't start at all.
