WPEDKS Double Speed Cast Iron Worm Gearbox — WP Series

Some industrial drive specifications accumulate requirements until they describe a combination that challenges standard catalogues entirely: double-stage worm reduction, D-split housing for field maintainability, IEC motor flange for direct overhead motor mounting (S-type), and K-type hollow bore output for coupling-free shaft connection. The WPEDKS Double Speed Cast Iron Worm Gearbox satisfies all five requirements in one ISO-9001-certified cast iron body — the most specification-rich unit in the WPE double-stage range and the engineering answer to the most demanding slow industrial drive configuration.

■ 5-Feature Integration: D-Split + IEC-S + K Hollow + Double-Stage + Cast Iron

The WPEDKS combines more engineering features than any other unit in the WP double-stage range. Each feature is fully engineered into the housing — not field-modified or compromised by the others.

■ D-Split Housing Maintains Accessibility Despite Maximum Features

Adding K hollow bore and S-IEC flange to the double-stage housing does not eliminate the D-split housing access advantage. The cover still removes independently of motor, driven shaft, and both worm stage components.

■ IEC Flange (S-Overhead) + K Hollow Bore: Zero Couplings on Both Sides

Motor connects directly to S-IEC flange overhead (no input coupling). Driven shaft inserts into K hollow bore (no output coupling). The WPEDKS operates with zero external coupling hardware on either side — the cleanest possible double-stage drive.

■ Double-Stage Ratio 1/200–1/900: Full WPE Performance

The WPEDKS delivers identical output torque and ratio performance to the WPEA/WPES — the addition of K hollow bore and D-split housing does not compromise the double-stage worm gear performance.

■ S-Type IEC Flange: Overhead Motor Drops Directly On

Motor is lowered onto the upward-facing IEC flange. Four flange bolts secure the connection. Input shaft keyway engages motor shaft. Drive is operational. S-type flange engineering is identical to the WPEDS — proven overhead motor mounting geometry.

■ ISO 9001:2000 + CE: Full Certification for Full Feature Set

Every WPEDKS is manufactured under ISO 9001:2000 quality management with CE marking — meeting the most stringent industrial procurement certification requirements globally.

⚙ Premium Slow Drives — All Features Required

Applications demanding simultaneously: overhead IEC motor (D+S), hollow bore output (K), extreme ratio (double-stage), and field-maintainability (D-split) represent the WPEDKS core market — pharmaceutical, specialty chemical, and precision process machinery.

⚔ Pharmaceutical & Biotech Reactor Premium Drives

Biotech reactors requiring GMP-compatible overhead motor mounting, hollow bore agitator shaft connection, extreme ratio (2–5 RPM agitation), and accessible housing for CIP validation represent the WPEDKS’s pharmaceutical market application.

⚒ Specialty Chemical Mixing — Full Feature Integration

Specialty chemical mixers where every feature is non-negotiable: motor overhead, IEC direct mount, hollow bore shaft, double-stage ratio, accessible housing for maintenance without process shutdown.

⚊ Advanced OEM — Minimum Component Count Design

OEM machine builders targeting minimum BOM component count for slow drive stations choose WPEDKS to eliminate: overhead motor adaptor, output coupling, second gearbox stage, and solid housing — four components in one catalogue unit.

☷ R&D Pilot Plant — Premium Slow Drive Specification

R&D pilot plant equipment where all engineering options are maximised — overhead motor, hollow bore, extreme ratio, accessible service — uses the WPEDKS as the engineering-optimised drive specification.

✎ ISO 9001:2000 Certified

Every WPEDKS is manufactured, assembled, and tested under the ISO 9001:2000 quality management framework. We were among the first in our industry category to achieve this certification.

✎ CE Marking

Full CE marking confirms compliance with EU Machinery Directive 2006/42/EC — covering safety, design standards, and manufacturing quality for mechanical power transmission equipment including double-stage worm gearboxes.

✎ Pre-Shipment Testing (Every Unit)

Noise test (below 72 dB(A) at rated load), oil leak test (30-minute pressurisation, both chambers), torque transmission test (output torque within ±5% of rated). Failed units are reworked — not shipped.

✎ Matched-Pair Manufacturing

Both worm wheel sets for each double-stage unit are manufactured in the same production batch, ensuring tooth profile consistency between primary and secondary stages. This matched-pair quality assurance is unique to our double-stage production process.

“WPEDKS on all our GMP reactor overhead drives. Overhead IEC motor, hollow bore shaft, accessible housing, and double-stage ratio satisfies every requirement of our pharmaceutical validation protocol. The most complete drive unit we have specified in 20 years of pharmaceutical engineering.”

“WPEDKS on our 10,000L bioreactor agitators. All five features were specified requirements — confirmed the WPEDKS was the only standard catalogue unit satisfying all of them. After 30 months of 24/7 pharmaceutical production, every unit is in perfect condition.”

“WPEDKS drives our specialty polymer reactor mixers. The zero-coupling-both-sides architecture was a specific requirement for our explosion-proof zone classification. Cast iron housing, IEC overhead mount, hollow bore output — all confirmed to our hazardous area specification.”

“WPEDKS satisfies our complete reactor drive specification. Five-feature integration replaced a five-component arrangement. Cost saving plus simplification. Build quality consistently excellent. Occasional lead time extension during peak demand is the only inconvenience.”
