Description
WPDKS Triple-Feature Cast Iron Worm Reducer — Product Overview
Le WPDKS is the most fully specified single-speed worm reducer in the WP series, combining all three auxiliary features in one FC20+ cast iron housing. The D-type split housing enables in-situ worm wheel maintenance. The S-type top-entry IEC flange mounts the motor overhead without an adaptor plate. The K-type hollow bore output accepts the driven shaft directly without a coupling.
For overhead-driven shaft-mount applications — food processing conveyors, pharmaceutical agitators, packaging turntables — the WPDKS eliminates the motor adaptor, the output coupling, and the teardown downtime from a single drive station simultaneously.

WPDKS Worm Reducer — Core Features
■ D-Split Housing — Cover Off, Motor Stays
Split below the IEC flange joint. Remove the housing top cover without touching the motor bolts — full worm wheel access with the overhead motor in place.
■ S-Type IEC Flange — Motor Bolts On Overhead
Top-entry IEC 72-1 flange eliminates the motor adaptor and the lateral motor projection. Motor mounts in four bolts from above — the most compact overhead motor drive in the WP series.
■ K-Type Hollow Bore — No Output Coupling
H7-tolerance through-bore accepts the driven shaft directly. No coupling hardware — shorter installed drive length, no coupling lubrication, no coupling fatigue failure.
■ Three Components Replaced by One
WPDKS replaces motor adaptor + worm reducer + output coupling. Reduces BOM count by two SKUs, installation time by approximately 55%, and total drive length by 80–250 mm across the size range.
■ FC20+ Cast Iron — Suitable for Wash-Down Environments
Cast iron resists cleaning chemical exposure in food and pharmaceutical installations better than aluminium. The WPDKS sealing system maintains ingress protection in wet cleaning cycle environments.
■ Output Torque to 3,025 Nm — Full WP Rating
Triple features do not reduce torque capacity. The WPDKS size 250 delivers the same 850–3,025 Nm as the WPDA and WPDKA at each ratio — the worm gear internals are identical.
WPDKS Worm Reducer — Industry Applications
⚔ Food Processing Conveyors
Overhead IEC motor keeps electrical connections away from food contact zones. Hollow bore eliminates the coupling exposed to washdown cleaning chemicals. Split housing enables hygienic inspection access without motor removal.
☵ Pharmaceutical & Chemical Agitators
Clean, compact drive configuration with no external coupling hardware minimises contamination risk around vessel openings. Annual inspection via split cover with motor in-place reduces validated maintenance procedure complexity.
⚒ Packaging Turntable & Indexing Drives
WPDKS achieves the minimum overhead drive envelope for packaging machine turntable and index station drives — overhead motor, direct shaft bore, and in-situ maintenance all in a single compact unit.
⚊ Overhead Conveyor & Elevator Head Drives
In applications with restricted headroom above the drive, WPDKS overhead motor configuration and compact housing achieve the lowest total installed height in the WP product series.

■ Certification des matériaux FC20+
Les pièces moulées des carters sont vérifiées par des certificats d'usine pour la nuance FC20 : résistance à la traction minimale de 220 MPa, dureté de 160 à 200 HB. Un contrôle par ultrasons des défauts est effectué sur les pièces de taille 135 et supérieure.
WPDKS Worm Reducer — Customer Reviews
“WPDKS on our food processing conveyor head drives. Overhead IEC motor, hollow bore on the head shaft, split housing for cleaning inspections — three requirements satisfied with one unit. Excellent.”
“Used WPDKS-100 on our overhead-driven mixer shafts. Direct motor overhead, shaft through the bore, split cover for annual inspection without motor removal. Reduced maintenance time by 60%.”
“WPDKS drives our packaging machine turntable shafts. D+K+S gave us the smallest possible overhead drive envelope in a very constrained machine layout. No compromises needed.”
“Very functional unit. Triple DKS combination is the right choice for our overhead shaft-mount agitator drives. Would like better documentation on oil volume for combined S+K orientation.”
