WPKZ Single Speed Cast Iron Worm Reducer — WP Series

Vessel nozzle drives that require a coupling-free shaft connection face a specific engineering challenge: the Z-type flange mounts on the vessel, but the driven shaft needs to enter without a coupling. The WPKZ resolves this by combining the Z-type circular flange housing with a K-type hollow bore output. Mount the Z-flange to the vessel nozzle, insert the driven shaft through the hollow bore, key it, and the drive is complete — no coupling at the vessel interface.

This is the standard architecture for vessel-mounted shaft drives in food processing, pharmaceutical, and chemical industries where coupling hardware at the vessel nozzle level creates contamination risk or complicates validation documentation.

■ K+Z: Flange Mount + Coupling-Free Shaft Output

The only WP reducer that combines vessel nozzle flange mounting with hollow bore shaft insertion. No coupling hardware at the vessel nozzle level — the shaft passes through the K-bore directly.

■ Z-Type 360° Rotational Positioning

Rotate the circular flange housing to any angular position during installation — directing the K-bore to precisely align with the driven shaft axis before bolting to the vessel nozzle.

■ Hollow Bore 22.8–64.4 mm Across 7 Sizes

Bore diameters from 22.8 mm (size 50) to 64.4 mm (size 135) cover the driven shaft diameters typical of process vessel agitator and conveyor shaft applications.

■ T-Type Top-Entry Input for Overhead Motor

Input shaft enters from above, positioning the motor directly overhead the vessel nozzle — the standard arrangement for vessel-top drive installations in process industries.

■ FC20+ Cast Iron for CIP Environments

Z-flange mounting at vessel nozzle level exposes the housing to cleaning-in-place chemicals and steam. FC20+ cast iron provides better chemical and moisture resistance than aluminium.

■ No Coupling Hardware at Vessel Interface

Eliminating the output coupling removes one contamination risk point, one lubrication maintenance point, and one fatigue failure mode from the vessel nozzle drive — essential in GMP-regulated production environments.

⚔ Food Processing Vessel Shaft Drives

Z-flange to vessel nozzle, shaft through K-bore — no coupling in the product zone. Clean drive architecture that simplifies GMP compliance documentation and reduces contamination risk.

☵ Pharmaceutical Mixer Shaft Drives

Coupling-free vessel nozzle drive for bioreactors and mixing vessels. K-bore eliminates the shaft coupling from the validated vessel boundary — simplifying change control and periodic inspection protocols.

⚒ Chemical Process Vessel Agitators

In chemical environments where coupling hardware requires compatible materials, WPKZ eliminates the coupling entirely — no compatibility verification required for the drive-to-shaft interface.

☷ Beverage Tank Discharge Drives

Z-flange mount to tank outlet nozzle with hollow bore for the discharge shaft — compact, coupling-free drive that contributes to the clean-zone design of beverage processing equipment.

■ आईएसओ 9001:2000 प्रमाणित उत्पादन

प्रत्येक इकाई का निर्माण ISO 9001:2000 गुणवत्ता प्रबंधन के अंतर्गत किया जाता है। कच्चे माल का निरीक्षण, प्रक्रिया के दौरान की जाँच और अंतिम संयोजन परीक्षण पूरी तरह से प्रलेखित होते हैं और प्रत्येक इकाई के सीरियल नंबर से इनका पता लगाया जा सकता है।

■ सीई मार्किंग — यूरोपीय संघ मशीनरी निर्देश 2006/42/ईसी

पूर्ण सीई अनुपालन यांत्रिक शक्ति पारेषण के लिए यूरोपीय सुरक्षा और डिजाइन मानकों के अनुपालन की पुष्टि करता है, जो यूरोपीय संघ, ब्रिटेन, ऑस्ट्रेलिया और न्यूजीलैंड के बाजारों में निर्यात का समर्थन करता है।

■ शिपमेंट से पहले परीक्षण: शोर, रिसाव, टॉर्क

प्रत्येक यूनिट तीन परीक्षणों से गुजरती है: निर्धारित भार पर 68 dB(A) से कम शोर, 30 मिनट का दबाव रिसाव परीक्षण, और निर्धारित टॉर्क के ±5% के भीतर आउटपुट टॉर्क। जो यूनिटें मानकों के अनुरूप नहीं होतीं, उन्हें संशोधित किया जाता है और भेजा नहीं जाता।

■ FC20+ सामग्री प्रमाणन

हाउसिंग कास्टिंग को एफसी20 ग्रेड के लिए मिल प्रमाणपत्रों द्वारा सत्यापित किया जाता है: न्यूनतम 220 एमपीए तन्यता शक्ति, 160-200 एचबी कठोरता। साइज 135 और उससे ऊपर के मॉडलों पर अल्ट्रासोनिक दोष परीक्षण किया जाता है।

“WPKZ-80 on our vessel nozzle agitator shaft drives. Z-flange to nozzle, shaft through the K-bore — no coupling at the vessel flange level. Clean installation, no coupling contamination risk.”

“Used WPKZ-100 on our column-mounted shaft drives. Z-flange to column, driven shaft through the hollow bore. Rotating Z-mount to align the shaft precisely took two minutes — no bracket fabrication.”

“WPKZ on our food processing vessel drives. Shaft inserts through K-bore, Z-flange on nozzle — eliminates coupling hardware entirely. Very clean drive architecture for food plant requirements.”

“Good K+Z combination for vessel shaft applications. WPKZ-70 working well on our small process vessels. Would welcome a smaller size 40 mm for very compact vessel nozzle installations.”
