The Wacker Neuson Water Pump Complete is a genuine OEM component designed for the APT4S and APT4T pump series, including standard, surge brake, electric brake, and cold weather configurations. As a direct factory replacement, this assembly ships as a complete unit and restores full pumping function without the need to source individual internal components. Fitting the full range of APT4S and APT4T models — including cold weather variants — this part ensures your pump returns to service with the correct OEM specifications intact.
Key Features
- Genuine OEM Pump Integrity — Manufactured by Wacker Neuson to the same internal clearances and flow ratings as the original unit, maintaining consistent hydraulic performance across the pump assembly.
- Complete Assembly Replacement — Supplied as a fully assembled water pump complete, allowing direct swap-out at the pump housing without rebuilding individual internal components.
- Broad APT Series Compatibility — Fits APT4S (with skid) and APT4T (surge brake and electric brake) models, including all cold weather variants across both series.
- Sustained Flow Performance — A correctly functioning water pump complete maintains rated flow output and prime; a worn or failed unit causes pressure loss, reduced discharge, and potential dry-run damage to downstream components.
- Verified Part Number Match — Part number 5200020098 is confirmed across six APT4S and APT4T machine configurations, so you can order with confidence that this is the correct assembly for your unit.
The water pump complete is the core fluid-moving assembly in a dewatering or transfer pump. It draws liquid into the pump housing and discharges it at the rated flow and pressure by converting engine power into hydraulic energy through the impeller and volute. When this assembly wears or fails — through impeller damage, seal degradation, or internal erosion — the pump loses prime, output drops sharply, or it stops moving fluid entirely, making timely replacement critical to keeping the machine productive on site.
