WPDO D+O Cast Iron Worm Reducer — Product Overview

Vertical agitator and mixer applications typically require three separate items: a motor adaptor, a gearbox, and either a right-angle adapter or vertical-output configuration. The WPDO addresses all three directly: the D-type split housing enables in-situ maintenance, the integrated IEC motor flange eliminates the adaptor plate, and the O-type output shaft exits vertically upward — ready to connect directly to the agitator or driven shaft above.

With output torques up to 3,025 Nm and 12 standard sizes from 40–250 mm centre distance, the WPDO serves the full range of water treatment, chemical processing, and food industry vertical drive applications without custom fabrication.

WPDO Worm Reducer — Core Features

■ O-Type Vertical Upward Output — Direct Agitator Connection

Output shaft exits vertically upward, connecting directly to agitator shafts and vertical driven equipment without right-angle brackets or bevel gear stages.

■ IEC Motor Flange — Four-Bolt Direct Motor Mount

Integrated IEC 72-1 flange eliminates the motor adaptor plate. Motor bolts on in four bolts — no coupling, no alignment tool, no adaptor fabrication.

■ D-Type Split Housing — In-Situ Cover Removal

Two-piece cast iron housing allows the top cover to be removed while motor and vertical output shaft remain connected. Worm wheel inspection in-situ during standard maintenance windows.

■ Output Torque to 3,025 Nm — Full WPDA Capacity

The worm gear internals are identical to the WPDA. D+O configuration does not reduce torque — WPDO size 250 delivers 850–3,025 Nm.

■ FC20+ Cast Iron — Splash and Moisture Resistant

Vertical agitator environments often involve process fluid splash. FC20+ cast iron housing provides better corrosion resistance than aluminium in wet industrial environments.

■ Weight 5–396 kg Across 12 Sizes

Full industrial power range from compact size 40 mechanism drives to heavy-duty size 250 agitator drives — all within the standard WPDO product series.

WPDO Worm Reducer — Industry Applications

WPDO cast iron worm reducer water treatment and chemical agitator applications

⚔ Water Treatment Agitators

WPDO vertical upward output connects directly to clarifier, flocculator, and aeration basin agitator shafts. IEC motor bolts on without adaptor, D-split cover opens for maintenance without shaft disconnection.

☵ Chemical & Pharmaceutical Mixers

No coupling or adaptor hardware in the process environment. D-split cover access for annual inspection without removing the motor from the vessel mounting frame.

⚒ Food Processing Vertical Conveyors

Vertical screw and bucket conveyor drives benefit from WPDO direct-motor, direct-shaft connection — fewer external components mean fewer contamination risk points in food plant environments.

⚊ Industrial Wash Agitator Drives

In industrial parts washing and surface treatment lines, vertical agitator drives with IEC motor and upward output simplify the mechanical design and reduce the number of sealing interfaces in a wet environment.

Frequently Asked Questions — WPDO Worm Reducer

▶ What distinguishes the WPDO from the WPO?
The WPO uses a standard solid input shaft and solid one-piece housing. The WPDO adds the D-type split housing (for in-situ cover removal) and the integrated IEC motor flange (eliminating motor adaptor), while retaining the O-type vertical upward output.
▶ Can the WPDO top cover be removed while the motor and vertical shaft are connected?
Yes — that is the maintenance advantage of the D-type split housing. The cover splits below the IEC flange joint, allowing worm wheel inspection and replacement in-situ without disconnecting either the motor or the vertical output shaft.
▶ Is the WPDO oil level adjusted for O-type vertical output orientation?
Yes. With the output shaft pointing up, fill to the WPDO-specific oil level mark. The oil volume differs from horizontal-output WPDA configurations to maintain adequate worm wheel submersion in O-type orientation.
▶ What output torque does the WPDO size 250 deliver?
The WPDO size 250 delivers 850–3,025 Nm at 1/5–1/60 ratio — identical to the WPDA size 250 since the worm gear internals are the same. D+O configuration affects mounting and output direction only, not torque capacity.
▶ Does the WPDO require a motor support bracket?
For sizes 200 and 250 with heavier motors, a support bracket is recommended to prevent bending stress on the horizontal IEC flange joint. Sizes 40–175 are designed for cantilevered motor mounting within IEC specifications.
