WPWEO Double Speed Cast Iron Worm Reducer — Product Overview
The WPWEO provides the universal WPW body flexibility for vertical upward output applications at extreme ratios. Where the WPEO covers a single fixed-direction input configuration, the WPWEO accepts input from multiple WPW shaft directions — serving OEM machine builders and process plant engineers who need a universal vertical agitator drive platform accommodating different motor position constraints.

WPWEO Double Speed Worm Reducer — Core Features
■ WPW Universal Body + O Vertical Output + Double Stage
The WPWEO extends the WPWE universal body to include O-type vertical upward output at dual-stage extreme ratios. Universal shaft direction input configurations, vertical upward output, and ratios from 1/200 to 1/900+ — covering all installation geometries for ultra-slow vertical agitator drives.
■ O-Type Output at All WPW Input Directions
Vertical upward output shaft direction is maintained regardless of which WPW input shaft direction configuration is used — universal input geometry, consistent vertical upward output.
■ Same 6,050 Nm Output Torque — Universal Body Does Not Affect Capacity
WPWEO worm gear internals are identical to WPEO at equivalent size combinations. Universal body and O-type designation do not reduce torque capacity.
■ Dual Independent Oil Chambers — O-Type Adjusted Volumes
Both stage chambers have O-type orientation adjusted oil volumes per the WPWEO lubrication table. Independent fill, gauge, and drain for each stage.
■ Weight Range 19.5–476 kg — Full Industrial Drive Range
From compact size 40–70 (19.5 kg) to heavy-duty size 155–250 (476 kg), covering all standard vertical agitator and lift mechanism drive requirements.
■ FC20+ Dual-Chamber Universal Housing — O-Type Stable
Cast iron dual-chamber housing maintains oil submersion geometry and inter-stage alignment in O-type vertical output orientation across all WPW shaft direction configurations.
WPWEO Worm Reducer — Industry Applications
⚔ Universal Vertical Agitator Drive Platform
WPWEO universal body covers multiple motor position configurations for vertical agitator drives in process vessels — single product model for different plant layouts requiring extreme ratio slow agitation.
☵ Multi-Orientation Vertical Mixer Drives
OEM mixer machine builders with varying motor position requirements standardise on WPWEO universal body for all extreme-ratio vertical mixer shaft drives — one product, all input orientations.
⚒ Water Treatment Infrastructure Agitators
Wastewater and water treatment agitators requiring ultra-slow output speeds (below 5 rpm) from multiple motor position configurations use WPWEO universal body at 1/200–1/900+.
⚊ Process Plant Universal Slow Vertical Drives
Chemical and food process plants with slow vertical drives at multiple input shaft positions use WPWEO to standardise the extreme-ratio vertical drive on one universal product model.
