WPEDO Flange-Mounted Vertical Double Speed Worm Gear Reducer \u2014 Motor-Direct 1\/200\u20131\/900 Drive for Vertical Process Equipment & Wastewater Systems<\/h1>\n

Deep wastewater treatment tanks, tall vertical stirring towers, and multi-storey process vessels all share a common drive challenge: a very high reduction ratio must be delivered in a vertical orientation, from a motor that connects directly without couplings, in a configuration that fits the spatial constraints of the structure. The WPEDO flange-mounted vertical double speed worm gear reducer<\/strong> resolves all three requirements simultaneously \u2014 combining IEC motor direct mounting, two-stage 1\/200\u20131\/900 reduction, and multi-direction mounting capability (including full vertical) in a single cast iron unit.<\/p>\n

The WPEDO is particularly distinguished by its multi-face oil-fill system<\/strong>, which ensures both worm gear stages remain correctly lubricated regardless of the mounting angle \u2014 an essential feature absent in many competitor vertical-mount products that ignore the oil level consequences of non-horizontal installation. Available in 9 size groups<\/strong>, motors 0.12\u20135.5 kW, ratios 1\/200\u20131\/900. Gi\u1edbi thi\u1ec7u v\u1ec1 Everpower<\/a> | Request a Layout Consultation<\/a><\/p>\n<\/section>\n

Product Structure \u2014 IEC Flange + Two-Stage Cascade + Multi-Orientation Design<\/h2>\n
\n
\"WPEDO<\/div>\n
\n

The WPEDO combines an IEC motor flange at the first-stage input with a two-stage worm cascade and a housing body that incorporates multi-face oil-fill ports, reinforced output shaft bearings, and multiple mounting face preparations. This allows the unit to operate correctly in horizontal, inclined, and vertical orientations while maintaining adequate lubrication at both worm gear stages \u2014 a critical engineering requirement for two-stage units in non-horizontal service.<\/p>\n\n\n\n\n\n\n\n

\u2705 Key Features & Benefits<\/h2>\n
\n
\n
<\/div>\n

Motor-Direct + Two-Stage + Vertical \u2014 Three Critical Requirements in One<\/h3>\n

The WPEDO uniquely satisfies three simultaneous vertical-drive requirements: no input coupling (IEC flange), extreme reduction ratio (1\/200\u20131\/900), and safe non-horizontal mounting with correct oil lubrication at both stages. No single-stage product meets the ratio requirement; few two-stage products address the lubrication consequences of vertical mounting. Keywords: motor-direct vertical double speed worm gearbox, IEC flange two-stage vertical reducer.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

Multi-Face Oil System \u2014 Both Stages Lubricated in Any Position<\/h3>\n

The WPEDO’s most critical engineering feature is its multi-face oil-fill system, which ensures both the first-stage and second-stage worm gear meshes are correctly lubricated at any supported mounting angle. A two-stage gearbox in vertical orientation without this feature will have at least one stage under-lubricated \u2014 leading to accelerated wear and early failure.<\/p>\n<\/div>\n

\n
<\/div>\n

Strong Self-Locking for Vertical Process Safety<\/h3>\n

At combined ratios of 1\/400 and above, the WPEDO self-locks under static conditions, preventing agitator shafts, pump shafts, or vertical conveyors from back-driving under gravity when the motor is de-energised. Combined with motor-direct mounting, this provides both operational efficiency and passive safety for vertical process equipment.<\/p>\n<\/div>\n

\n
<\/div>\n

Rapid Motor Replacement in Vertical Structures<\/h3>\n

The IEC pilot register allows motor swap in 15\u201320 minutes, even in vertical shaft structures and elevated process vessel locations where coupling disassembly and alignment would otherwise require significant scaffolding and downtime.<\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

Reinforced Vertical Load Bearings<\/h3>\n

The output shaft bearing arrangement is specifically designed for the combined axial and radial loads generated in vertical and inclined mounting. This is not a standard horizontal gearbox rotated vertically \u2014 the bearing selection reflects actual vertical load vectors, ensuring bearing life targets are met in vertical service.<\/p>\n<\/div>\n

\n
\u2699\ufe0f<\/div>\n

Two-Stage Precision for Very Slow Vertical Processes<\/h3>\n

Both worm pairs ground to ISO 1328 Grade 7 deliver smooth, uniform output at the ultra-low speeds (1\/200\u20131\/900 \u00d7 motor speed) essential for clarifier rakes, vertical agitators, and deep well pump auxiliaries where non-uniform output speed causes process disruption.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
