Description
WPZ Z-Type Flange-Mount Cast Iron Worm Reducer — Product Overview
Standard foot-mount worm reducers require a flat, rigid, horizontal base surface — a constraint that rules them out for vessel nozzle drives, column-mounted drives, and wall-mounted applications. The WPZ solves this with a Z-type circular flange housing that bolts directly onto any flanged surface: vessel nozzles, structural column flanges, wall brackets, or custom flanged frames — without a flat base.
The circular flange also enables free rotational positioning during installation, allowing the horizontal output shaft to be oriented in any required direction before the flange bolts are tightened. Combined with the T-type top-entry input shaft, the WPZ is the purpose-built choice for vessel-top and column-mounted drive applications in food processing, chemical, and pharmaceutical industries.

WPZ Flange-Mount Worm Reducer — Core Features
■ Z-Type Circular Flange — Vessel & Column Direct Mount
The circular flange housing face bolts directly onto vessel nozzles, column flanges, and wall-mount brackets. No flat base surface required — no custom bracket fabrication.
■ 360° Rotational Output Positioning
Rotate the WPZ housing to any angular position on the mounting flange before tightening — directing the horizontal output shaft precisely toward the driven equipment without custom brackets or angular adapters.
■ T-Type Top-Entry Input Shaft
The input shaft enters from above, enabling the motor to sit directly overhead of the mounting flange — the natural arrangement for vessel-top drive installations.
■ Sizes 50–135 mm — Purpose-Sized for Process Drives
Z-type flange mounting is most effective for smaller mechanism and process drives. WPZ covers the 50–135 mm centre distance range where vessel nozzle and column mounting is most commonly required.
■ Output Torque 17–562 Nm — Full Process Drive Range
From small 17 Nm mixer drives (size 50) to 562 Nm agitator drives (size 135) — covering the torque requirements of standard process vessel drive applications.
■ FC20+ Cast Iron Housing for Process Environments
Resistant to the moisture, cleaning chemicals, and process fluid splash common in food, chemical, and pharmaceutical vessel drive environments.
WPZ Worm Reducer — Industry Applications

⚔ Food Processing Vessel Drives
WPZ Z-flange bolts directly to vessel nozzles on mixing tanks, blending vessels, and cooking vats. Output shaft directs to the conveyor or discharge mechanism without custom fabrication.
☵ Chemical Reactor Drives
Flange mount to reactor vessel nozzles positions the drive directly at the vessel — no floor space penalty, and the compact circular flange suits tight vessel spacing in chemical plant layouts.
⚒ Column-Mounted Process Drives
In tall-column installations where floor space is unavailable, WPZ mounts to structural column flanges at the required elevation — no floor frame, no pedestal fabrication.
☷ Wall-Mounted Mechanism Drives
WPZ circular flange adapts to wall-mounted flanged brackets, enabling drive installation in wall-adjacent locations where foot-mount reducers cannot be fitted.

WPZ Worm Reducer — Customer Reviews
“WPZ-80 on our vessel nozzle drives at our food plant. Z-flange bolts directly onto the vessel nozzle — no custom bracket fabrication needed. Output shaft points to the conveyor drive wherever we need it.”
“Used WPZ-100 on our chemical reactor vessel drives. Circular flange mount to the vessel nozzle gave us a compact, clean drive installation with no floor space penalty.”
“WPZ on our column-mounted drives in our production plant. The Z-flange lets us rotate the housing to any output direction. Saved significant custom fabrication cost on multiple installations.”
“Good flange-mount reducer for vessel applications. WPZ-60 on our small mixing vessels. T-type input from above works well with our overhead motor configuration. Would like more sizes below 50 mm.”
