WPWKO Worm Reducer — Core Features

■ WPW Universal Body + K Hollow Bore + O Vertical — Coupling-Free Vertical Drive

Universal P-housing with coupling-free K hollow bore in O-type vertical upward direction — agitator shaft inserts directly from below in any WPW input configuration.

■ K+O Hollow Bore Vertical — No Coupling at Agitator Interface

Agitator shaft inserts through the K-bore vertically — no coupling hardware at the vessel shaft interface in any input orientation.

■ Universal Input Direction — Motor Position Flexible

All WPW input shaft directions supported — motor position does not constrain the K+O hollow bore vertical output.

■ Shaft-Mount + Vertical Hollow Bore — Compact Drive

Torque arm boss enables shaft-mounting in any WPW orientation with K-bore vertical agitator connection.

■ Output Torque to 4,440 Nm — K+O Full Capacity

Torque ratings identical to WPW.

■ One Product — All K+O Vertical Input Positions

Eliminates direction-specific K+O vertical reducer variants.
