WPWEDO Double Speed Worm Reducer — Core Features
■ Universal Body + IEC + O Vertical + D-Split + Double Stage
The WPWEDO combines the WPW universal input shaft direction flexibility, IEC direct motor mounting, O-type vertical upward output, D-split in-situ maintenance cover, and dual-stage extreme ratios in a single FC20+ cast iron housing — the maximum-specification motorised universal vertical agitator drive.
■ IEC Flange + O Vertical + D-Split + Double Stage — Complete Feature Set
Four features combined: direct motor mount, vertical upward output, in-situ maintenance, extreme ratio. Universal WPW body adds the fifth: multiple input shaft directions.
■ Output Torque to 9,066 Nm — Universal Motorised Vertical Drive
WPWEDO worm gear internals are identical to WPEDO. Universal WPW body does not reduce torque capacity — size 155–250 delivers up to 9,066 Nm.
■ D-Split Cover — In-Situ Access with Motor and Agitator Shaft Connected
Cover removes while IEC motor and vertical agitator shaft remain connected. Both worm stage chambers accessible in-situ for worm wheel inspection and planned maintenance.
■ Multiple WPW Input Shaft Directions — Universal Motor Positioning
Universal body accommodates different motor position requirements across the installed base — one WPWEDO model covers all motor positioning configurations for vertical agitator applications.
■ Independent Dual Oil Chambers — O-Type Adjusted Volumes
Two independently sealed chambers with O-type adjusted oil volumes per the WPWEDO lubrication table.
