The HK(L) is Hongjiu’s all-stainless-steel vertical multistage pump for high-head, clean-water applications. All wetted components — pump body, impellers, guide vanes, shaft — are AISI 304 stainless steel as standard. 11 frame sizes cover 0.4–85 m³/h with head up to 245 m; three motor options scale from simple on/off to IE5 permanent magnet.

High-rise building water supply boosting · Boiler feed and condensate return (up to 110°C) · RO / UF / NF membrane feed · Agricultural and landscape irrigation · Fire protection parallel configuration
HK vs HKL — what is the difference? HK uses stainless steel connection flanges; HKL uses cast iron flanges. Hydraulic performance and wetted materials are identical.
Is single-phase power available? Yes — models up to 2.2 kW are available in single-phase 220V/50Hz.
