WPDS Single Speed Cast Iron Worm Gearbox — WP Series

Industrial processes that require a vertical motor configuration — motor mounted from above — combined with direct IEC motor flange connection and no separate coupling hardware demand a very specific gearbox: S-type input geometry, D-type split housing, and an integrated IEC motor flange. The WPDS Single Speed Cast Iron Worm Gearbox delivers exactly this combination. Building on the D-type split housing architecture with its field-maintenance advantages, the WPDS adds the S-type upward input shaft orientation required for overhead motor mounting, serving OEM machine builders who need the leanest possible bill of materials for vertical motor drive configurations.

■ S-Type Input + D-Type Housing: The Vertical Motor OEM Solution

No other single cast iron worm gearbox combines upward input shaft geometry (S-type) with an integrated IEC motor flange (D-type). The WPDS is purpose-designed for this exact application requirement.

■ Split Housing Enables Rapid Field Maintenance

The D-split housing means the worm wheel and bearings can be inspected and replaced without disconnecting the motor from the IEC flange or the driven shaft from the output — saving hours on scheduled maintenance in difficult-to-access overhead positions.

■ IEC Motor Frame Compatibility: 56–350 Frame Range

Full compatibility with A02, Y-series, and international IEC motor frames across the WPDS size range. At size 250, M16 flange bolts accept motors up to 315 frame — suitable for the heaviest industrial motor applications.

■ Precision Oil Channel Engineering for S-Geometry

Like the WPS, the WPDS oil circuit is specifically calibrated for upward input shaft orientation. The worm mesh submersion depth, oil slinger geometry, and air vent position are all configured for the S-type bearing and shaft loads.

■ Chemical-Resistant Paint System — Marine-Grade Finish

Standard epoxy primer with polyurethane topcoat resists the chemicals, cleaners, and humidity typical of food processing and chemical plant overhead environments.

■ Nameplate Compatibility with Australian Standards

CE marking, ISO 9001:2000 certification, and permanent metal nameplate meet Australian industrial procurement requirements for traceable mechanical components.

⚔ Vertical Motor OEM Machines

Machine builders who use overhead motors across their product line standardise on WPDS to eliminate adaptor plates and flexible couplings from their BOM, reducing per-machine cost and assembly time.

☵ Hygienic Processing — Dairy & Beverage

Dairy and beverage equipment with washdown-duty overhead motors use the WPDS for its combined advantages: IEC flange direct mount (no corrosion-prone coupling hardware), S-input geometry for the overhead motor, and cast iron durability for the wet environment.

⚊ Elevator & Hoisting Equipment

Lightweight lifting and hoisting equipment frequently positions the motor overhead. The WPDS provides the required S-input geometry with IEC motor flange for these vertical motor hoist drive applications.

⚒ HVAC & Ventilation Equipment

Roof-mounted HVAC equipment with vertically-oriented motor drives uses the WPDS for compact, direct motor coupling in the restricted space inside roof plant rooms.

⚛ Pharmaceutical & Chemical Mixing

Sterile mixing equipment with overhead motor mounting requires sealed, cleanable drive components. The WPDS cast iron housing and direct IEC flange connection minimise exposed surfaces and seal interfaces in clean-room-adjacent environments.

✎ ISO 9001:2000 Certified

We hold ISO 9001:2000 International Quality System Certification — the first in our industry category to achieve this standard. Every WPDS is manufactured, assembled, and tested under this quality framework.

✎ CE Marking

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

✎ Pre-Shipment Testing

Every unit undergoes: Noise test (below 68 dB(A) at rated load), Oil leak test (30-minute pressurisation), and Torque transmission test (output torque within ±5% of rated). Failed units are reworked — not shipped.

✎ FC20+ Material Certification

Housing castings are verified by material test certificates for FC20 grade (220 MPa minimum tensile strength). Hardness testing (160–200 HB) and ultrasonic testing for internal defects are performed on size 135 and above.

“WPDS gearboxes drive our pasteuriser conveyor overhead positions. The IEC flange direct mount means no coupling in the washdown zone — a significant hygiene improvement. Split housing means we service them without a scaffold — a safety improvement too. Excellent product.”

“Standardised WPDS units across our chemical mixing equipment line. The S-input geometry and IEC direct mount reduced our drive assembly time by 35% per machine. Quality is consistently excellent across every order.”

“We changed to WPDS on our pasta dough mixer overhead drives. The split housing meant our maintenance team could service the gearbox without removing the motor or the agitator paddle assembly. Reduced mixer maintenance time from 4 hours to 45 minutes.”

“WPDS units drive our tomato processing conveyor overhead positions. Cast iron durability in a high-moisture washdown environment has exceeded our expectations. The direct IEC motor mount was a major simplification for our local maintenance team.”
