Delta 50 Series

The Udor Delta 50 is a high-volume triple diaphragm spray pump delivering up to 14.0 GPM (53.0 L/min) at a maximum pressure of 580 PSI (40 bar). With its anodised aluminium body and stainless steel valves, this self-priming pump provides excellent corrosion resistance for agricultural and horticultural spraying. The higher operating pressure offers superior penetration through dense vegetation such as thick gorse, making it a popular choice among New Zealand farmers and contractors. Available in three mounting configurations for PTO, tractor shaft, or belt-drive applications. AES Waterblasters is New Zealand’s sole Udor distributor with over 25 years of experience and full spare parts availability.
