WPWA Universal Speed Cast Iron Worm Reducer — WPW Series

Universal P-housing with A-type (below) input shaft direction fixed. Provides the mounting versatility of the WPW body for applications where the A-type input orientation is specified.

The WPW P-housing accommodates all five standard shaft direction configurations in a single casting — eliminating the need for direction-specific housing variants. Input power from 0.06 kW (size 40) to 98 kW (size 250), output torques from 2.2 Nm to 4,440 Nm across 11 standard sizes.

■ WPW Universal Body with A-Type Below Input

Universal P-housing with A-type (below) input shaft direction fixed. Provides the mounting versatility of the WPW body for applications where the A-type input orientation is specified.

■ Standard Worm Reducer in Universal Housing

WPWA delivers the familiar bilateral A-type solid input with the universal body’s multi-orientation mounting capability — the standard foot-mount reducer that can be mounted in 5 positions.

■ 11 Sizes: 40–250 mm, Output Torque to 4,440 Nm

Complete industrial drive range in the universal P-housing. Size 40 at 1/5 delivers 2.2 Nm; size 250 at 1/60 delivers 4,440 Nm.

■ FC20+ Cast Iron Universal P-Housing

Single-cast FC20+ grey cast iron P-housing provides 3× vibration damping versus aluminium and maintains shaft alignment across all 5 mounting orientations.

■ N150–N220 Lubrication — Optimised for Universal Housing

Lower viscosity lubricant than WP-series equivalents, optimised for the universal P-housing oil distribution geometry across all mounting orientations.

■ Bilateral A-Type Input — Motor from Either Side

Standard bilateral solid input shaft accepts motor connection from either side — maintaining full WPA-equivalent motor coupling flexibility within the universal housing.

⚒ OEM Machines Requiring Universal Mounting

Machine builders who need A-type input with universal mounting position flexibility use WPWA — one product accommodates all installation orientations without changing the reducer model.

⚊ Conveyor Drives with Multiple Mounting Options

Conveyor drive applications where the same A-type input reducer must be installed in different orientations (horizontal, wall-mount, inverted) standardise on WPWA for the universal body.

☷ Agricultural Equipment Standard Drive

Agricultural machines using standard A-type input worm reducers gain universal mounting flexibility with WPWA — fitting the same unit in multiple orientations on the same machine.

⚙ Process Equipment Universal A-Type Drives

Process equipment standardising on A-type input reducers uses WPWA for the universal body’s flexibility to accommodate changed installation orientations without a product change.

■ ISO 9001:2000 Certified Production

Every WPW unit is manufactured under ISO 9001:2000 quality management. Raw material inspection, in-process checks, and final testing are documented and traceable.

■ CE Marking — EU Machinery Directive 2006/42/EC

Full CE compliance for export to EU, UK, Australian, and New Zealand markets.

■ Pre-Shipment Testing: Noise, Leak, Torque

Noise below 68 dB(A) at rated load, 30-minute pressurisation leak test, and output torque within ±5% of rated. Non-conforming units reworked before shipment.

■ FC20+ Material Certification

Housing castings verified by mill certificates: minimum 220 MPa tensile strength, 160–200 HB hardness.

“WPWA on our OEM machine. Universal body lets us fit the same reducer in three different mounting orientations across the machine. Standard A-type input — same motor couplings as our WPA units.”

“Used WPWA on our conveyor system. Multiple mounting positions, one product model with universal body. Standard A-type input works with our existing motor hardware.”

“WPWA on our agricultural equipment. Universal body with A-type input — same reducer fitted in horizontal, wall-mount, and inverted positions. Significant inventory simplification.”

“Good universal body A-type unit. WPWA-90 in multiple positions. Working well. Would appreciate a clear comparison chart between WPWA and WPA for our engineering selection.”
