Veichi's VWF series are stainless-steel, water-filled AC submersible pumps for deep wells, agricultural irrigation and clean-water supply, powered by variable-frequency motors from 2.2 to 110 kW (350–400 V / 50 Hz). Sub-series span 6″ to 10″ bodies — 6VWF17/30/42/60, 8VWF75/95 and 10VWF120/150 — with rated flows from 17 to 150 m³/h, heads up to 518 m on the 6VWF17 line, and flows up to 180 m³/h on the 10VWF150 line.

Maximum submergence is 70 m with a pH tolerance of 6.5–8.5, built to NEMA installation standards. As variable-frequency AC pumps they are made to run on solar power through Veichi's SI-series solar pump inverters — see the recommended drives below.
