WPES Double Speed Cast Iron Worm Reducer — Product Overview
Single-stage worm reducers achieve ratios up to 1/60. When applications demand 1/200, 1/500, or 1/900 — solar trackers, valve actuators, slow-speed conveyors, and positioning drives — a second worm stage is the engineering answer. The WPES places two matched worm stages in tandem in a single cast iron housing, delivering ratios from 1/200 to over 1/900 in one compact, foot-mount unit with no intermediate shafting, no external coupling between stages, and no additional mounting frame.
Combines two worm stages with S-type top-entry input, enabling the motor to mount overhead while achieving ratios that n… The dual-stage architecture uses matched tin-bronze worm wheels and 20CrMnTi worm shafts at both stages, providing consistent mesh quality and noise performance across the full ultra-high ratio range.

WPES Double Speed Worm Reducer — Core Features
■ S-Type Top-Entry + Double Stage — Overhead Motor at 1/200–1/900+
Combines two worm stages with S-type top-entry input, enabling the motor to mount overhead while achieving ratios that no single-stage reducer can reach. Reduces lateral machine footprint at ultra-high ratio.
■ Same Torque Ratings as WPEA — S Input Does Not Reduce Capacity
S-type top-entry designation changes input shaft direction only. WPES worm gear internals and torque ratings are identical to the WPEA — up to 6,050 Nm from size combination 155–250.
■ Matched Dual-Stage Worm Wheels — Both Stages
Both reduction stages use precision-matched ZCuSn10Pb1 tin-bronze worm wheel pairs for consistent inter-stage ratio accuracy across the full 1/200–1/900+ range.
■ Overhead Motor Reduces Lateral Footprint
S-type input positions the motor vertically above the dual-stage reducer. In confined-width installations where lateral motor projection would exceed available space, WPES resolves the constraint without sacrificing ratio capability.
■ Bilateral Input Option Maintained
The S-type top-entry input shaft extends on both sides, accepting coupling connections from either direction — the same flexibility as the standard WPS single-stage unit.
■ FC20+ Dual-Chamber Cast Iron Housing
Single-cast dual-chamber housing from FC20+ grey cast iron maintains inter-stage alignment across the operating temperature range. No bolted joint between stages — worm shaft centreline geometry is set at manufacture.
WPES Worm Reducer — Industry Applications
☀ Overhead-Motor Solar Tracker Drives
WPES combines ultra-high ratio reduction with overhead motor geometry — reducing the lateral projection of the drive assembly on solar tracker frames where horizontal space between panels is constrained.
⚒ Valve Actuators in Tight Lateral Spaces
In pipe galleries and valve manifolds where lateral clearance beside the actuator drive is limited, WPES overhead motor positioning achieves the required 1/200–1/900+ ratio within the available installation envelope.
⚙ Slow-Speed Drives in Narrow Machine Frames
Machinery with constrained lateral width — narrow conveyors, slim elevator frames, compact processing lines — uses WPES to achieve ultra-high ratio reduction while keeping the motor above the frame rather than beside it.
⚊ Overhead-Driven Positioning Systems
Where the mechanical design requires the motor to be above the driven equipment and the output speed must be below 5 rpm, WPES is the standard double-stage solution.

WPES Double Speed Worm Reducer — Customer Reviews
“WPES on our solar panel tracker drives where horizontal clearance between panel arrays is limited. Overhead motor plus 1/600 ratio gives us the tracking speed we need in a narrower drive envelope than the WPEA configuration.”
“Used WPES on our narrow-frame conveyor drives. Motor overhead keeps the drive within the frame width. 1/500 ratio gives us correct belt speed from a standard 4-pole motor. Good solution.”
“WPES on valve actuator drives in our pipe gallery. Limited lateral clearance made WPES the only workable option. Overhead motor, 1/800 ratio, correct torque output for the valve size. Works well.”
“Good S-type double-stage unit for overhead motor applications. WPES-80–135 on our positioning drives. Overhead motor reduces machine width. Would appreciate a combined S+K variant for shaft-mount applications.”
