WPWED Double Speed Cast Iron Worm Gearbox — WP Series

Process equipment designers needing both universal installation versatility AND direct IEC motor connection in a double-stage extreme-ratio gearbox face a combination that standard catalogues rarely address as a single product. The WPWED Double Speed Cast Iron Worm Gearbox combines the WPW-series universal body (5 shaft direction configurations), D-type IEC motor flange, and double-stage worm reduction in a single D-split cast iron housing. The standard specification for OEM machinery platforms where one motorised double-stage drive unit must cover multiple machine configurations with direct motor mounting.

■ Universal W-Body + IEC D-Flange + Double-Stage: The Universal Motorised Slow Drive

WPWED combines the three most requested features of double-stage motorised drives: universal orientation (W-body), direct motor connection (D-IEC flange), extreme ratio (double-stage). One product. All orientations. All slow process speeds.

■ D-Split Housing Enables In-Situ Service Regardless of Orientation

The D-split housing cover can be removed in all 5 shaft direction configurations without disturbing the motor or driven shaft connections — universal in-situ serviceability across all orientations.

■ 5 Shaft Direction Configurations — All Available with IEC Flange

All 5 shaft direction configurations (A–E) are available for the WPWED — maintaining full universal orientation support even with the IEC motor flange added.

■ IEC Motor Range: M8 to M16 Bolts, Full Power Range

WPWED IEC flange accepts all standard IEC motor frames from fractional-horsepower (0.12 kW) to 5.5+ kW across the size range, covering all motor power requirements for slow industrial process drives.

■ Double-Stage Ratio 1/200–1/900 with Full Torque

The combination of universal body, D-flange, and D-split housing does not compromise double-stage output torque ratings. WPWED delivers the same maximum torques as the WPEDA for each size combination.

■ Anti-Corrosion Coating — Suitable for Diverse Process Environments

Standard epoxy/polyurethane coating provides corrosion resistance across the diverse process environments where the WPWED’s universal versatility finds application.

⚙ OEM Platform Motorised Slow Drives — Multiple Orientations

OEM machine platforms requiring motorised slow drives (IEC direct mount) in multiple machine configurations use the WPWED as their single motorised double-stage SKU — universal body handles all orientations.

⚒ Process Plant Standardised Motorised Drives

Process plants standardising their slow drive specification to one motorised double-stage product across all plant orientations use the WPWED for universal body plus IEC direct mount.

⚔ Slow Food Processing — Universal Motorised Configuration

Food processing facilities with multiple equipment lines in different orientations use the WPWED to standardise their slow motorised drive specification — IEC motor direct mount and universal body in one model.

⚊ Multi-Axis Slow Drives — Automated Production Lines

Automated production lines with slow drives in multiple axes use the WPWED as their standard motorised slow drive unit — one product serves all axis orientations.

☷ Industrial Maintenance Standardisation

Maintenance departments standardising spare parts benefit from the WPWED’s universal body + IEC flange combination — one spare gearbox model covers motorised slow drives across the entire plant.

✎ ISO 9001:2000 Certified

Every WPWED 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.

“WPWED is our standard motorised slow drive specification across all product lines. Universal body, IEC motor direct, double-stage ratio — one catalogue number serves our entire range. Spare parts holding reduced from 12 models to 1. Quality is consistent and IEC motor dimensions match precisely.”

“We standardised our complete slow drive range on WPWED. Universal body and IEC direct mount across all orientations made this possible. Previously had 8 different gearbox models. Now 1. Significant cost and complexity reduction.”

“WPWED drives our slow processing equipment across multiple product lines with different installation orientations. Universal body + IEC direct mount = one product for all. Quality excellent across all delivered batches.”

“WPWED universal motorised double-stage on our processing line. 5-orientation universal body was the key feature for our multi-position installation. IEC motor direct mount works perfectly with our standard 4-pole motors.”
