The <strong>WPDA Single Speed Cast Iron Worm Gearbox<\/strong> solves this with a D-type split housing that integrates an IEC-standard motor flange directly into the gearbox structure. Drop your motor onto the flange, tighten four bolts, and the drive is complete \u2014 no coupling, no adaptor, no alignment headaches. Delivering output torques up to 3,025 Nm, the WPDA is the preferred choice for motor manufacturers, OEM machine builders, and maintenance engineers upgrading legacy conveyor and pump drives across Australia and Southeast Asia.<\/p>\n<p style=\"margin:0;\"><a href=\"\/nl\/contact-us\/\" style=\"color:#2d6a2d;font-weight:bold;text-decoration:underline;\">&#9993; Request a Quote<\/a> &nbsp;|&nbsp;
