WPDKZ Maximum-Feature Vessel-Top Cast Iron Worm Reducer — Product Overview
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.

WPDKZ Worm Reducer — Core Features
■ 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.
WPDKZ Worm Reducer — Industry Applications
⚔ 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.
Ever Power Manufacturing Quality — WPDKZ Worm Reducer
■ ISO 9001:2000 Certified Production
Every unit is manufactured under ISO 9001:2000 quality management. Raw material inspection, in-process checks, and final assembly testing are fully documented and traceable to each unit’s serial number.
■ CE Marking — EU Machinery Directive 2006/42/EC
Full CE compliance confirms adherence to European safety and design standards for mechanical power transmission, supporting export to EU, UK, Australian, and New Zealand markets.
■ Pre-Shipment Testing: Noise, Leak, Torque
Every unit passes three tests: noise below 68 dB(A) at rated load, 30-minute pressurisation leak test, and output torque within ±5% of rated. Non-conforming units are reworked — not shipped.
■ FC20+ Material Certification
Housing castings are verified by mill certificates for FC20 grade: minimum 220 MPa tensile strength, 160–200 HB hardness. Ultrasonic defect testing on size 135 and above.
WPDKZ Worm Reducer — Customer Reviews
“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.”
