CHM-Z Self-priming VFD Motor Multi-stage Centrifugal Intelligent Inverter Water Pump

Product Features

1. Intelligent Frequency Conversion (VFD Control)

The CHM-Z series is equipped with an advanced Variable Frequency Drive (VFD) system, which automatically adjusts motor speed based on real-time water demand. This not only ensures constant water pressure but also significantly reduces energy consumption by avoiding unnecessary high-speed operation. It helps extend the motor’s service life and reduces operational costs over time.

2. Self-Priming Function – Hassle-Free Start-Up

Thanks to its self-priming capability, the pump can automatically evacuate air from the system and draw water into the impeller chamber without manual priming. This feature simplifies installation and startup, especially in environments where initial water levels are unstable or when dry-run protection is needed.

3. Multi-Stage Centrifugal Design for High Head & Stable Flow

The CHM-Z utilizes a multi-impeller (multi-stage) centrifugal system that delivers high head (up to 60 meters) and consistent flow even at long distances or in vertically demanding applications. This design is ideal for pressure boosting in high-rise buildings, long piping systems, or precision-controlled irrigation systems.

4. Durable & Corrosion-Resistant Structure

The pump body and internal components are made from stainless steel and high-performance engineering plastics, offering strong resistance to rust, corrosion, and mechanical wear. This makes the CHM-Z suitable for a variety of clean water and light industrial fluid transfer tasks, even in challenging environments.

5. Low Noise, Smooth Operation

Designed with a balanced rotor and noise-dampening motor housing, the pump operates quietly even under heavy load. This is ideal for indoor or residential use, where noise can be a critical factor in equipment selection.

Installation & Maintenance

The CHM-Z pump features a plug-and-play design, making installation simple and efficient even for first-time users. It comes pre-wired and factory-tested, requiring only standard plumbing and electrical connections. No specialized tools or complex configuration is needed during setup.

The system is compatible with clean water and light industrial fluids that are non-corrosive and free of solid particles. For environments with stricter requirements, inlet filtration is recommended to extend service life.

Each unit is equipped with a pre-configured VFD controller, suitable for most common applications. If you have specific operating parameters, custom programming or adjustment via the control panel is also supported, with easy-to-follow instructions.

Maintenance is minimal — the pump is designed for long-term operation with occasional checks. We recommend periodic inspection of the impeller chamber, seals, and electrical connections every 6–12 months, depending on usage intensity. No daily upkeep is necessary under normal conditions.
