The Udor MTP138 is a heavy-duty PTO speed multiplier designed to drive Udor ZETA series diaphragm pumps from a standard 540 RPM tractor power take-off. With a 1:3.8 multiplication ratio, the MTP138 converts the tractor’s 540 RPM PTO input to approximately 2,050 RPM output — the optimal operating speed for Udor ZETA diaphragm pumps used in agricultural and horticultural spraying. Rated at 13.6 HP, this multiplier is built for the demands of broadacre crop spraying, orchard and vineyard treatment, and pasture management across New Zealand farms.
