"The Zhongguantai submersible pump series is a flood control and emergency drainage equipment developed by Huangshan Zhongguantai Special Equipment Co., Ltd. (a member of the China Fire Protection Association, a high-tech enterprise, and has passed ISO9001 quality system certification). It is specifically designed for emergency drainage scenarios such as flood control, urban flooding, and water conservancy projects. It is widely used in fields such as fire protection, water conservancy, municipal services, and the military, providing efficient and reliable drainage capabilities to support disaster prevention, mitigation, and relief efforts. This series currently includes two core products: 500m3/h and 1000m3/h. Both feature intelligent control, high strength and durability, and comprehensive safety protection. They are equipped with complete auxiliary equipment to meet the drainage needs of different scenarios.

Ⅰ. Core common features

1. Core performance: Both use permanent magnet synchronous motors, with insulation class F, protection class IP68, and can operate stably underwater; they have automatic alarm and protection functions for overvoltage, undervoltage, overcurrent, phase loss, short circuit, overheating, etc., and can automatically or manually restore in case of faults, ensuring equipment safety.

2. Materials and durability: The pump body can be selected from lightweight high-strength alloy or stainless steel materials. The water flow components (impeller, impeller chamber, etc.) are made of wear-resistant and corrosion-resistant stainless steel in one piece. The hardness of the impeller Vickers is ≥1000HV, the filter screen is 304 stainless steel, which is easy to disassemble and clean, and can withstand 25mm solid particles, adapting to complex water quality environments.

3. Intelligent control system: Equipped with an integrated control cabinet (cold-rolled steel material), protection class IP55 (500m3/h) or IP54 (1000m3/h), supporting one-to-one/one-to-two control, one-click start and soft start/shutdown, capable of real-time monitoring of motor temperature, current, flow, etc., and some support remote control; it comes with an external power socket for convenient power supply for rescue operations.

4. Ancillary equipment: All come with dedicated water hoses (polyurethane material of polyester long filaments, wear-resistant and waterproof), JHS grade waterproof cables (national standard copper core, IP67 waterproof connector), high-strength polyurethane float rings (one-piece foaming molding, still usable after damage), and maintenance tool kits to ensure rapid deployment and maintenance."
