Product Overview
The Danfoss M46-20901 axial piston pump, designated by the full ordering code MPV046CBBATABBCAA BDDCHAGGCNNN***, is a high-performance variable displacement piston pump from the Danfoss MPV series. It operates on the proven swashplate principle, where an inclined swashplate drives multiple pistons within a rotating cylinder barrel to generate precise, high-pressure hydraulic flow. The MPV046 frame size delivers a nominal displacement of 46 cm³/rev and is engineered for demanding industrial circuits requiring accurate pressure and flow control, high volumetric efficiency, and long service life. The comprehensive model code defines the exact configuration, including displacement, control type, mounting flange, shaft, ports, and seal options, ensuring a direct-fit solution for OEM and replacement applications.
