\u2705 Key Features & Benefits<\/h2>\n
\n
\n
<\/div>\n

Five Features \u2014 The Peak of the WPW Series<\/h3>\n

The WPWEDKO provides: IEC motor-direct (no input coupling) + two-stage 1\/200\u20131\/900 ratio + hollow bore (no output coupling) + extended multi-direction output reach + universal multi-orientation mount. No other product in the WPW series combines all five. The WPWEDKO is specified when the application demands the maximum feature set from a single product number. Keywords: five-feature double speed hollow shaft universal worm reducer, motor-direct hollow bore ultra-high ratio multi-direction gearbox.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

Offshore & Marine \u2014 Hollow Bore + Vertical + Ultra-High Ratio<\/h3>\n

Offshore platform agitator drives and marine vessel slow-speed auxiliary systems commonly need all five WPWEDKO features simultaneously: IEC motor-direct (for maintenance access in confined spaces), ultra-high ratio (for very slow rotation), hollow bore (for coupling-free direct shaft engagement), extended output reach (for agitator stub shaft depth), and vertical\/inclined mounting (for offshore structural constraints).<\/p>\n<\/div>\n

\n
<\/div>\n

IEC Motor Swap in Confined Offshore Spaces<\/h3>\n

In offshore and marine installations where working space is at a premium, the IEC flange enables motor replacement from one side of the unit without disturbing the hollow bore agitator shaft connection at the other end \u2014 critical in offshore machinery spaces where equipment removal is hazardous or impractical.<\/p>\n<\/div>\n

\n
<\/div>\n

Self-Locking Prevents Back-Drive at Any Mounting Angle<\/h3>\n

At combined ratios \u22651\/400, the WPWEDKO self-locks in all supported orientations \u2014 vertical, inclined, and horizontal. For offshore agitator drives and marine vessel equipment where back-driving under process pressure or vessel motion is a risk, this passive self-locking provides an important safety margin.<\/p>\n<\/div>\n

\n
<\/div>\n

Correct Oil System for Multi-Orientation Double-Speed Service<\/h3>\n

Two worm gear stages in a multi-orientation housing require carefully configured oil ports to ensure both stages are correctly lubricated in each rated orientation. The WPWEDKO multi-face oil port system and position-specific oil fill documentation address this dual-stage lubrication requirement for each mounting position.<\/p>\n<\/div>\n

\n
<\/div>\n

9 Size Groups for Complete Offshore & Marine Range<\/h3>\n

Nine size groups accepting 0.12 kW to 5.5 kW and bore 30\u2013110 mm cover the complete range of offshore platform, marine vessel, and heavy energy industry slow hollow shaft drive requirements within the WPWEDKO product.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
