Product Overview:

The PM5(m)-EMH series is an intelligent permanent-magnet multistage pump system comprising a permanent-magnet motor, an intelligent variable-frequency controller, a pressure tank, a pressure sensor, and a five-way check valve. It achieves intelligent constant-pressure control via the integrated pressure sensor and features high efficiency and energy savings, corrosion and rust resistance, a compact and smart design, ease of use and maintenance, and durable reliability.

Product Applications:

Primarily used for domestic water supply, equipment integration, pipeline boosting, garden irrigation, greenhouse watering, aquaculture, industrial and mining operations, enterprise facilities, high-rise building water supply and drainage, and circulation systems for central air conditioning and district heating.

Application Conditions:

1. Suitable for low-viscosity liquids that are non-flammable, non-explosive, and non-vaporizing, and free of solid particles or fibers. The liquid must not chemically react with the pump materials. A higher-power motor is required when pumping liquids with density or viscosity exceeding that of water.

2. Liquid temperature range: 0°C to 60°C

3. Maximum ambient temperature: +40°C

4. Maximum working pressure: 10 bar

5. Liquid pH value: 6.5 to 8.5

Motor:

1. High-efficiency permanent-magnet synchronous motor; energy efficiency exceeds IE5 standards

2. Protection class: IPX5

3. Insulation class: Class F

Variable-Frequency Controller:

1. Input power: Single-phase 220V–240V; Three-phase 380V–480V

2. Input frequency: 50Hz/60Hz

3. Protection class: IP55
