The vertical multistage constant pressure VFD pump is a centrifugal type with sensor-controlled constant pressure functionality, offering compact design. Using variable frequency technology, it auto-adjusts flow and pressure based on demand. Its multistage impeller design enables high-head delivery, making it ideal for high-rise water supply, fire systems, and industrial fluid transport. Features include stable operation, energy efficiency, and low noise.

Features
1.Fully automatic operation:Not only starts/stops automatically but also intelligently identifies water consumption, compensating water supply by pressure difference (supply as much as the pressure deficit).
2.High pressure & head:Vertical multistage pump for pressurization, with max head up to ~200m, suitable for small-to-medium flow & high-head scenarios.
3.Compact & aesthetic design:Pump and controller integrated with the motor, featuring small size, compact structure, and elegant appearance.
4.Hygienic & clean:Flow-through components made of full 304 stainless steel/chrome-plated brass, minimizing secondary contamination of the medium.
5.High-precision constant pressure:High-precision sensors and closed-loop control technology enable real-time stepless speed regulation, ensuring stable water pressure.
6.Multiple protections:Controller offers conventional protections (overcurrent/overload/overvoltage/undervoltage/phase loss/water shortage) to ensure safe operation.
7.Human-machine interaction:Equipped with a concise yet powerful code-based HMI, allowing parameter optimization via settings.
8.Customizable pressure:Set target pressure values conveniently through the interface to meet diverse water demand.
9.Cost-effective:Adopts backpack-type VFD with integrated control module (no extra modules), balancing economy and practicality.
