Choosing the right deep well pump starts with well diameter, required flow and total head. YINGZHI offers four high-speed permanent magnet variable frequency deep well series, each supplied with a matched variable frequency controller. The G100 series reaches 0-6000 r/min for deep-well water lifting, mountain water supply and agricultural irrigation; G130 and G150 run at 0-4500 r/min where larger flow or higher head is required; G200 operates at 0-4500 r/min for large-volume water supply, sprinkler and drip irrigation. Together they cover farm breeding, agricultural and forestry irrigation and high-rise building water supply. Full model data — max. flow (m3/h), max. head (m), voltage (V), current (A), outlet diameter (mm), pump and packaging dimensions, net/gross weight — is listed in the YINGZHI 2026 product catalogue.
