WPZ Single Speed Cast Iron Worm Reducer — WP Series

The WPZ Z-type cast iron worm reducer mounts via a circular flange directly onto vessel nozzles, column flanges, or wall flanges — no flat base surface required. Sizes 50–135 mm, ratio 1/5–1/60, output torque 17–562 Nm, weights 7–80 kg.

Descrição

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

WPZ flange mount worm reducer food processing and vessel drive 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.

Frequently Asked Questions — WPZ Worm Reducer

▶ What makes the WPZ Z-type different from foot-mount WP reducers?
Foot-mount WP reducers (WPA, WPS, etc.) require a flat, rigid horizontal surface for the base plate. The WPZ Z-type housing has a circular flange face that bolts directly onto any flanged surface — vessel nozzles, column flanges, wall mounts — without a flat base.
▶ What flange bolt circle dimensions does the WPZ use?
The WPZ flange bolt circle dimensions are specified per size in the dimension drawing. Contact Ever Power with your vessel nozzle or mounting flange PN/DN specification and size requirement for a flange compatibility check before ordering.
▶ What is the output torque range for the WPZ series?
WPZ size 50 delivers 17–43 Nm (ratio 1/5–1/50). WPZ size 135 delivers 460–562 Nm (ratio 1/40–1/60). The WPZ covers a smaller size range (50–135 mm) than the WPA because Z-type flange mounting is typically required for smaller mechanism and process drives.
▶ How does the T-type top-entry input work on the WPZ?
The WPZ input shaft enters from directly above (T-type). The motor or driving equipment sits above the gearbox and connects via a standard shaft coupling to the upward-pointing worm shaft. This arrangement suits vessel-top drives where the motor is positioned above the mounting flange.
▶ Can the WPZ horizontal output shaft be oriented to any rotational position?
The WPZ circular flange mount allows the housing to be rotated to any angular position relative to the mounting flange during installation, enabling the horizontal output shaft to be directed in any required direction — a flexibility that foot-mount reducers cannot offer.
