Udor E127 Electric Motor Reduction Gearbox

The Udor E127 is a purpose-built reduction gearbox designed to couple standard electric motors to Udor diaphragm pumps for agricultural spraying, chemical dosing, and industrial fluid transfer applications. By stepping down the motor’s output speed through a precision 2.778:1 gear ratio, the E127 delivers the exact RPM range that Udor diaphragm pumps require for optimal performance and longevity. This makes it the ideal drive solution for stationary and mobile electric-motor-driven spraying systems throughout New Zealand.

As the sole authorised Udor distributor in New Zealand, AES Waterblasters stocks the E127 gearbox alongside the full range of compatible Udor diaphragm pumps, ensuring you can source a complete pump-and-drive package from a single supplier with local technical support.
