Company Profile
Hunan Shenyu Emergency Technology Co., Ltd. is based in Changsha, Hunan, China, and specialises in portable, high-capacity, long-distance emergency water supply and drainage technology. The portfolio covers five lines: emergency submersible pumps, pump control systems, mobile pump trailers, rescue and drainage vehicles, and firefighting water supply systems — serving flood response, municipal pipeline repair, and firefighting where no hydrant network exists.
Technical Approach
Units are built around an electric pump architecture. Housings are formed from aviation-grade aluminium billet, forged and then hard anodised, which keeps unit weight down while improving corrosion and impact resistance in harsh conditions. Wetted parts are 304 stainless steel. The complete unit follows an integrated fluid–structure–electromagnetic design.
- Multi-layer composite sealing: hard-particle seal, sewage-side seal and mechanical seal, isolating solids from the fluid path.
- Anti-wrapping cutting impeller: shears floating debris to prevent clogging and stall.
- Efficiency: above 94% at 65% rated speed and above 94% at 120% load.
Products and Duty Range
Submersible pump units cover 100–1,000 m³/h and heads of 7–100 m, weighing 22–70 kg so that two operators can carry and deploy them. Four series — Regular, Heavy-Duty, Large-Flow and Special — cover different duty levels. Series-connection control allows heads to be added: a single DN250 line can deliver up to 500 m³/h at 80 m head.
Vehicle-based systems range from pickup-mounted rescue vehicles to super-heavy drainage trucks across six classes, with 25–280 kW power packs, up to ten pumps in parallel, 5,000 m³/h maximum drainage capacity and an operating radius beyond 500 m.
Manufacturing and Delivery
The factory is located at Unit 112, Building A1, Xinggongchang Industrial Park, Changsha Economic and Technological Development Zone. It handles pump assembly, control system integration and special vehicle conversion. Export configurations can be customised for destination voltage, frequency, phase, plug type and nameplate; body colour and logo customisation are available.
