767 Knapsack Power Sprayer Overview
The 767 knapsack power sprayer pairs a two-capacity choice — 20 L or 25 L, both customizable — with the pump platform WENXIN builds its backpack line around: 18 mm plunger, 25–30 MPa, 8 L/min, 7–8 m of throw for orchard and tall-crop coverage. Four engine options from 25.6 to 35.8 cc and 0.7 to 0.85 kW let a distributor run one model number across markets with different power habits. Its aluminum pump head can be built with twin air chambers or dual water inlets to order, and the standard 90 cm brass spray gun swaps for other gun types.
