WPDO Single Speed Cast Iron Worm Reducer — WP Series

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.

■ 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.

⚔ 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.

■ Produção com Certificação ISO 9001:2000

Cada unidade é fabricada sob o sistema de gestão da qualidade ISO 9001:2000. A inspeção da matéria-prima, as verificações durante o processo e os testes de montagem final são totalmente documentados e rastreáveis ​​até o número de série de cada unidade.

■ Marcação CE — Diretiva de Máquinas da UE 2006/42/CE

A conformidade total com a marcação CE confirma a adesão às normas europeias de segurança e de projeto para transmissão de potência mecânica, permitindo a exportação para os mercados da UE, Reino Unido, Austrália e Nova Zelândia.

■ Testes pré-embarque: ruído, vazamento, torque

Cada unidade passa por três testes: ruído abaixo de 68 dB(A) com carga nominal, teste de vazamento sob pressurização por 30 minutos e torque de saída dentro de ±5% do valor nominal. Unidades não conformes são recondicionadas — não são enviadas.

■ Certificação de Material FC20+

As peças fundidas da carcaça são verificadas por certificados de fábrica para a classe FC20: resistência à tração mínima de 220 MPa e dureza de 160–200 HB. Teste de defeitos por ultrassom em peças de tamanho 135 e superiores.

“WPDO on our clarifier agitator drives. IEC flange motor, vertical shaft output, split cover for annual inspection — all in one unit. No additional brackets or right-angle attachments needed.”

“Used WPDO-120 on our chemical vessel agitators. Direct motor flange eliminates the adaptor plate. D-split cover opens for inspection while the motor stays mounted. Very efficient design.”

“WPDO drives our vertical screw conveyors in a food processing plant. IEC motor bolts on in minutes. Vertical shaft connects to the screw directly. Split housing for hygiene inspection without full teardown.”

“Good D+O combination unit for our water treatment paddles. Motor mounts direct, vertical output connects to the paddle shaft. Would appreciate a size 165 between 155 and 175.”
