WPDKS Single Speed Cast Iron Worm Reducer — WP Series

De 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.

■ 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.

⚔ 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.

■ ISO 9001:2000-certifierad

Varje enhet tillverkas enligt kvalitetsledningsstandarden ISO 9001:2000. Råmaterialinspektion, kontroller under processen och slutprovning dokumenteras och kan spåras till varje enhets serienummer.

■ CE-märkning — EU:s maskindirektiv 2006/42/EG

Full CE-överensstämmelse bekräftar efterlevnad av europeiska säkerhets- och designstandarder för mekanisk kraftöverföring, vilket stöder export till marknaderna i EU, Storbritannien, Australien och Nya Zeeland.

■ Testning före leverans: Buller, läckage, vridmoment

Varje enhet klarar tre tester före leverans: buller under 68 dB(A) vid nominell belastning, 30 minuters läckagetest vid trycksättning och momentöverföring inom ±5% av nominellt värde. Icke-överensstämmande enheter omarbetas – levereras inte.

■ FC20+ Materialcertifiering

Gjutgods i hus verifieras med fabrikscertifikat för FC20-kvalitet: minst 220 MPa draghållfasthet, 160–200 HB hårdhet. Ultraljudsdefekttestning utförs på storlek 135 och uppåt.

“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.”
