WPDKZ Single Speed Cast Iron Worm Reducer — WP Series

For vessel-top drive applications in GMP-regulated food, pharmaceutical, and chemical industries, the WPDKZ is the complete solution. Four features in one FC20+ cast iron housing: the Z-type flange mounts directly on the vessel nozzle; the IEC motor flange accepts the motor without an adaptor; the K-type hollow bore receives the driven shaft without a coupling; and the D-type split housing opens for validated worm wheel inspection without disconnecting either motor or vessel mount.

The result is zero external coupling hardware at either the motor or output end, in-situ maintenance access, and direct vessel nozzle installation — all in seven standard sizes from 50–135 mm centre distance.

■ Z-Type Flange — Vessel Nozzle Direct Mount

Circular flange bolts to any flanged surface — vessel nozzles, column flanges, wall brackets. 360° rotational positioning during installation for precise output shaft orientation.

■ IEC Motor Flange — Motor Overhead, No Adaptor

Integrated IEC 72-1 flange at the top entry. Motor bolts on in four bolts without adaptor plate, coupling, or alignment tool — overhead motor, drive complete.

■ K Hollow Bore — Driven Shaft Inserts, No Coupling

H7-tolerance K-bore with GB/T 1095 keyway. Driven shaft inserts directly — no coupling hardware, no coupling maintenance, no coupling in the process or product zone.

■ D Split Housing — In-Situ Validated Inspection

Housing cover removes while IEC motor stays connected and Z-flange stays on vessel. Worm wheel access for GMP periodic inspection without disconnecting motor or vessel mount.

■ Zero External Couplings — Input and Output Both Direct

Neither motor end nor driven shaft end requires a coupling. Eight flange bolts (motor + vessel) and one keyed shaft insertion — the minimum possible external hardware count.

■ FC20+ Cast Iron for GMP Process Environments

Resists CIP cleaning chemicals, steam sterilisation, and process fluid splash. Preferred over aluminium in food, pharmaceutical, and chemical vessel drive applications for chemical compatibility and longevity.

⚔ GMP Food Processing Vessels

WPDKZ delivers the cleanest possible drive architecture for food plant vessel nozzle drives — no coupling hardware in the product zone, in-situ validated inspection access, and direct motor and shaft connections.

☵ Pharmaceutical Bioreactors

For validated bioreactor and mixing vessel drives, WPDKZ in-situ D-split inspection access without disconnecting motor or vessel mount satisfies GMP periodic inspection requirements with minimum validation re-work.

⚒ Chemical Reactor Vessel Drives

Zero external coupling hardware reduces the number of material compatibility checks required for chemical environment drive installation. Fewer components in the chemical environment means fewer failure modes and maintenance points.

⚛ Beverage Tank Agitator Drives

Compact WPDKZ installation on beverage tank nozzles eliminates the floor frame footprint and coupling hardware from the drive system — cleaner plant, tighter tank spacing, simpler sanitation.

■ 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.

“WPDKZ-100 on our pharmaceutical vessel top drives. IEC motor overhead, Z-flange to nozzle, K-bore on the agitator shaft, D-split for GMP inspection — all four requirements in one unit. Remarkable design.”

“Used WPDKZ-80 on our food plant mixing vessels. Zero coupling hardware in the process zone. D-split housing opens for hygiene validation inspection without any disconnection. Exactly what food plant engineers need.”

“WPDKZ on our chemical bioreactor vessel drives. IEC motor direct, vessel nozzle mount, shaft through bore, split cover for periodic inspection — nothing extra, nothing redundant.”

“Excellent four-function unit for vessel applications. WPDKZ-120 working perfectly on our beverage tank drives. Would appreciate a completed torque table for the KZ hollow bore configuration at all ratios.”
