Description
WPWDKO Universal Speed Cast Iron Worm Gearbox
The most comprehensively specified vertical drive in the universal speed series — combining IEC direct motor connection, hollow bore vertical output, D-split housing for field service, and universal installation orientation support — is the WPWDKO Universal Speed Cast Iron Worm Gearbox. D-type IEC motor flange, K-type hollow bore in the O-type vertical upward direction, D-split housing, and WPW universal body in one cast iron unit. For process engineers specifying the maximum-feature motorised hollow shaft vertical agitator drive across diverse vessel orientations, the WPWDKO is the definitive single-product catalogue solution.

Universal W-Body Structure
The WPW-series universal housing is manufactured as a single FC20+ grey cast iron casting with bore positions, keyway orientations, and oil channels configured for the selected shaft direction. All 5 shaft direction configurations (A/B/C/D/E) use the same casting geometry with specific machining per configuration.
Hardened 20CrMnTi steel worm shaft with case-hardened tooth flanks (55–60 HRC). The worm shaft and its bearings are selected for the specific input orientation of the model — A-type (below), S-type (overhead), or bilateral — ensuring rated bearing life in the correct load direction.
Tin-bronze ZCuSn10Pb1 alloy worm wheel machined to mesh precisely with the hardened worm shaft. The bronze material provides excellent anti-seizure properties and wear-in characteristics for the worm gear mesh.
Output shaft in quenched-and-tempered steel with double-lip oil seals rated for the specific output orientation (horizontal, vertical upward O-type, vertical downward X-type, side T-type, or extended V-type). Seal selection matches the hydrostatic pressure requirements of the installed orientation.
Single-stage oil bath lubrication. Oil fill port, oil gauge, vent plug, and drain plug are positioned for the selected shaft direction configuration. Fill quantities are specified per configuration in the installation guide — do not use generic fill values across configurations.
FC20+ cast iron foot-mount base integrated with the housing casting. Four mounting holes for B3 foot mounting. The base orientation is fixed for the selected shaft direction configuration. For shaft-mount (hollow bore) applications, the torque arm boss provides housing restraint.
Core Features & Benefits
■ 4-Feature Integration: D-IEC Flange + K Hollow Vertical + D-Split + Universal W-Body
The WPWDKO combines the four most requested motorised vertical drive features: IEC motor flange (D), hollow bore vertical output (K+O), in-situ maintenance (D-split), and universal orientation (W-body). Four specifications. One catalogue unit.
■ IEC Flange + K Hollow Bore: Zero Couplings Both Sides
Motor bolts to D-type IEC flange — no input coupling. Driven shaft inserts into K hollow bore vertical output — no output coupling. Complete zero-coupling-both-sides motorised hollow shaft vertical drive.
■ D-Split Housing: In-Situ Worm Wheel Access at Vessel Top
D-split cover removes without disturbing motor or agitator shaft — in all 5 shaft direction configurations. Motor stays mounted. Agitator shaft stays connected. Only the cover is removed for routine service.
All 5 shaft direction configurations (A–E) available with D+K+O+D-split features. Full universal orientation coverage maintained at maximum feature integration.
■ Full WP Performance: 4,796 Nm, 1/5–1/60
No performance derating for maximum feature combination. Full WP output torques and ratio range in all 5 shaft direction configurations.
■ CE + ISO 9001:2000 — Full Certification for Full Feature Set
All 5 configurations with D+K+O features are covered by ISO 9001:2000 and CE certification.
