Hengdong Pump Manufacturing Cluster

Hengdong's pump industry spans precision pumps for vehicle powertrains and submersible pumps for industrial and agricultural water use. Meihu develops lubrication, cooling and electrification products; Dongchuang supports automation and parts; Dadi makes submersible and related water pumps. Buyers should begin with duty and fluid conditions, then compare pump type, performance curves, bench tests and batch consistency rather than relying on a single park-wide capacity figure.

Formation and regional foundations

Hengdong Pump Manufacturing Cluster appears in authority list dated 2025, and each named entity uses its corresponding public record.

The authority list uses the name Hengdong Pump Manufacturing Cluster. A working review can begin with castings and pump-body casting and machining.
