Backed by extensive pump manufacturing expertise spanning decades, Shanghai Crowns Pump Manufacturing Co., Ltd. introduces its high-performance Split Case pump Diesel Fire Pump, purpose-built to deliver reliable emergency water supply in fire protection scenarios. This robust firefighting solution is designed to meet critical demands for high-flow water delivery during emergencies, combining durable construction with operational efficiency. The pump’s horizontal split-case design stands out for its maintenance-friendly features, allowing quick access to internal components without pipeline disassembly. This design ensures minimal downtime and enhanced convenience, making it a trusted choice for large-scale firefighting applications where reliability and easy servicing are paramount. Equipped with a heavy-duty diesel engine, the pump offers autonomous operation during power outages, guaranteeing continuous water supply when electrical systems fail.

With decades of hands-on experience in pump engineering, Shanghai Crowns Pump has perfected the art of crafting reliable fire safety solutions. Take their Long Shaft Fire Pump, for instance—this workhorse is built for one critical purpose: delivering dependable water flow when seconds matter in firefighting. Designed specifically for deep wells and underground water sources, it’s a lifeline in areas where surface water is scarce, like rural communities, sprawling industrial sites, or any location where traditional fire hydrants fall short. What sets this pump apart? The long vertical shaft isn’t just a feature—it’s a game-changer. It lets the pump tap into deep water reserves that other systems can’t reach, ensuring a steady supply even when the nearest water source is buried below ground. You don’t have to worry about it faltering under pressure, either. Built with rugged components and an efficient design, it’s tested to withstand the chaos of emergency situations, keeping water flowing consistently when every drop counts.

Shanghai Crowns Pump Manufacturing Co., Ltd. is deeply committed to the design, production, and distribution of top-notch water pumps. Our Immersed Multistage Pump CDLK/CDLKF series strictly adheres to ISO standards. This ensures not only remarkable efficiency but also outstanding durability. These pumps are ingeniously designed to perform extremely well in a wide range of applications. Whether it's for industrial cooling purposes, maintaining urban water systems, or lubricating precision machinery, they can operate consistently under different environmental conditions.

With over 20 years of manufacturing expertise, Shanghai Crowns Pump Manufacturing Co., Ltd. presents the CQ series magnetic drive pump (referred to as magnetic pump), a new type of centrifugal pump that applies the working principle of permanent magnet couplings. Absorbing advanced technologies, materials, and processes from domestic and international horizontal magnetic pump production, this pump successfully solves the technical challenges of easy damage to components like isolation sleeves and impellers in domestic magnetic pumps, achieving more refined performance. It features rational design, advanced craftsmanship, full sealing, no leakage, and corrosion resistance.
