WPDZ D+Z Vessel-Top Cast Iron Worm Reducer — Product Overview
Vessel-top drive applications in food processing, pharmaceutical, and chemical industries impose three requirements simultaneously: mount directly to the vessel nozzle without a floor frame, connect the motor without an adaptor plate, and enable worm wheel inspection without vessel shutdown or motor removal. The WPDZ meets all three.
The Z-type circular flange bolts directly to the vessel nozzle. The IEC motor flange accepts the motor directly overhead without an adaptor. The D-type split housing opens for worm wheel inspection with both motor and vessel connections intact. Seven sizes from 50–135 mm centre distance cover the full range of standard process vessel drive torque requirements from 6 Nm to 690 Nm.

WPDZ Worm Reducer — Core Features
■ Z-Type Flange Mount — Vessel Nozzle Direct
Circular flange housing bolts to vessel nozzle, column, or custom flanged frame. No floor frame, no pedestal, no flat base surface required — essential for vessel-top installations.
■ IEC Motor Flange — Motor Bolts Direct Overhead
Integrated IEC flange eliminates the motor adaptor plate. Motor connects in four bolts from above — the standard overhead motor arrangement for vessel-top drives.
■ D-Type Split Housing — In-Situ Maintenance on Vessel
Remove the housing cover while the IEC motor stays connected and the Z-flange stays bolted to the vessel. Worm wheel inspection and replacement in-situ during standard maintenance windows.
■ Rotatable Output Shaft Direction
The Z-type circular flange allows housing rotation before bolt tightening — directing the horizontal output shaft toward any required direction without angular adapter hardware.
■ 7 Sizes: 50–135 mm — Purpose-Sized for Process Vessels
Z-type flange mounting is most common in the 50–135 mm centre distance range where vessel nozzle drives are typically specified. Torques from 6 Nm to 690 Nm cover standard mixing and conveying vessel drive requirements.
■ FC20+ Cast Iron — CIP and Steam Compatible
FC20+ grey cast iron housing withstands cleaning-in-place chemical exposure and steam cleaning procedures common in food and pharmaceutical vessel environments.
WPDZ Worm Reducer — Industry Applications
⚔ Food Processing Tank & Vessel Drives
WPDZ Z-flange bolts to mixing tank nozzles. IEC motor overhead, output shaft rotatable to required direction. D-split cover for hygiene inspection without vessel shutdown.
☵ Pharmaceutical Bioreactor Drives
Validated maintenance protocol requires worm wheel inspection without disconnecting the motor or the vessel seal. WPDZ D-split cover allows this without disturbing the motor or the validated vessel nozzle seal.
⚒ Chemical Reactor Column Drives
Mount to reactor column nozzles at any elevation without floor frame or pedestal. IEC motor overhead, horizontal output to discharge conveyor or downstream equipment.
⚛ Beverage Production Tank Drives
In beverage plant tank farms where vessel spacing is tight, WPDZ Z-flange mount eliminates the floor frame footprint, allowing tighter tank spacing and improved plant layout efficiency.
