The <strong>WPDKZ hollow shaft vertical worm reducer<\/strong> delivers all four requirements in a single machined cast iron unit. The hollow bore slides directly onto the vertical screw or mixer shaft; the flange face accepts the motor directly; the output exits vertically \u2014 all in a footprint smaller than a traditional motor-coupler-gearbox-bevel chain. Designed for filling equipment, standing mixers, and dry powder screw conveyors where vertical integrated drives are the only practical choice.<\/p>\n<\/section>\n<p><!-- SPECS --><\/p>\n<section

The WPDZ has a solid output shaft, while the WPDKZ has a hollow bore output. Use WPDZ when your driven shaft has a protruding end and you need a coupling; use WPDKZ when you want the driven shaft to pass through the gearbox bore \u2014 eliminating the coupling entirely for a more compact, rigid drivetrain.<\/p>\n<\/details>\n<details style=\"border:1px solid #c0c8e8;border-radius:6px;padding:2.5%;margin-bottom:0.7em;\">\n<summary style=\"cursor:pointer;font-weight:bold;color:#1a2a6c;font-size:clamp(13px,1.3vw + 9px,16px);\">Is the WPDKZ self-locking at rest?<\/summary>\n<p style=\"margin:0.6em 0 0;color:#555;font-size:clamp(13px,1.2vw + 9px,15px);\">Worm gears are self-locking when the lead angle is less than the friction angle. At ratios \u22651\/25, the WPDKZ is effectively self-locking under static load, which prevents gravity-driven backdriving in vertical installations. For safety-critical hold applications, confirm with our engineering team for your specific load and ratio combination.<\/p>\n<\/details>\n<details style=\"border:1px solid #c0c8e8;border-radius:6px;padding:2.5%;margin-bottom:0.7em;\">\n<summary style=\"cursor:pointer;font-weight:bold;color:#1a2a6c;font-size:clamp(13px,1.3vw + 9px,16px);\">What hollow bore diameters are available for WPDKZ?<\/summary>\n<p style=\"margin:0.6em 0 0;color:#555;font-size:clamp(13px,1.2vw + 9px,15px);\">Standard hollow bore diameters (S) are: size 50 \u2192 20 mm, size 60 \u2192 25 mm, size 70 \u2192 30 mm, size 80 \u2192 35 mm, size 100 \u2192 40 mm, size 120 \u2192 45 mm, size 135 \u2192 60 mm.

For tank-top mounting, the foot flange is bolted to the vessel cover plate. An anti-rotation torque arm is recommended for sizes \u226580 to prevent housing rotation when the driven shaft experiences torque spikes.<\/p>\n<\/details>\n<details style=\"border:1px solid #c0c8e8;border-radius:6px;padding:2.5%;margin-bottom:0.7em;\">\n<summary style=\"cursor:pointer;font-weight:bold;color:#1a2a6c;font-size:clamp(13px,1.3vw + 9px,16px);\">Can I use a VFD with the WPDKZ?<\/summary>\n<p style=\"margin:0.6em 0 0;color:#555;font-size:clamp(13px,1.2vw + 9px,15px);\">Yes. WPDKZ is fully compatible with variable frequency drive (VFD\/inverter) controlled motors. When using a VFD at low speeds (below 600 r\/min input), ensure adequate motor cooling (use a motor with forced-air cooling fan if running extended periods below 30 Hz). The gearbox itself does not require modification for VFD use.<\/p>\n<\/details>\n<\/section>\n<p><!-- CTA --><\/p>\n<section style=\"border:2px solid #1a2a6c;border-radius:10px;padding:3%;text-align:center;margin-bottom:2em;background:#f0f2fb;\">\n<h2 style=\"color:#1a2a6c;margin:0 0 0.5em;font-size:clamp(16px,2vw + 10px,22px);\">Ready to Simplify Your Vertical Drive Design?<\/h2>\n<p style=\"color:#555;margin:0 0 1.2em;font-size:clamp(13px,1.3vw + 9px,16px);\">Send us your shaft diameter, required output speed, torque, and mounting arrangement.
