Traditional solutions bolt a bevel gearbox onto a standard reducer, adding weight, alignment complexity, and an extra failure point. The <strong>WPDZ vertical output worm reducer<\/strong> eliminates that compromise entirely \u2014 the motor mounts directly to the input flange face while the output shaft exits vertically, delivering torque straight down to pump impellers, agitator blades, or mixing paddles in a single rigid unit. Designed for pump stations, mixing vessels, and fermentation tanks where vertical drives are a spatial necessity, not an engineering afterthought.<\/p>\n<\/section>\n<p><!-- SPECS --><\/p>\n<section

The vertical output shaft is supported by pre-loaded tapered roller bearings specifically selected for combined radial and axial load capacity. Check the cantilever load table in the product datasheet; for heavy impellers, size up or contact us for a bearing-load calculation.<\/p>\n<\/details>\n<details style=\"border:1px solid #d7b8e0;border-radius:6px;padding:2.5%;margin-bottom:0.7em;\">\n<summary style=\"cursor:pointer;font-weight:bold;color:#4a1942;font-size:clamp(13px,1.3vw + 9px,16px);\">Does the WPDZ require any special lubrication for vertical mounting?<\/summary>\n<p style=\"margin:0.6em 0 0;color:#555;font-size:clamp(13px,1.2vw + 9px,15px);\">When mounted with the output shaft pointing downward (shaft-down config), the oil level must be topped up to a higher reference point than horizontal mounting. Use the shaft-direction oil-fill diagram on the nameplate. Recommended oil: ISO VG 220\u2013320 for normal ambient, ISO VG 320\u2013460 for hot environments.<\/p>\n<\/details>\n<details style=\"border:1px solid #d7b8e0;border-radius:6px;padding:2.5%;margin-bottom:0.7em;\">\n<summary style=\"cursor:pointer;font-weight:bold;color:#4a1942;font-size:clamp(13px,1.3vw + 9px,16px);\">Is the WPDZ available in sizes larger than 135?<\/summary>\n<p style=\"margin:0.6em 0 0;color:#555;font-size:clamp(13px,1.2vw + 9px,15px);\">The standard WPDZ series covers sizes 50\u2013135.
