Description :

Non negative pressure variable frequency water supply equipmentProduct Features

　　1. Save investment: Save about 50% of investment, no need to build reservoirs or roof water tanks, adopt stacked water supply, and reduce initial equipment investment.

　　2. Efficient and energy-saving, with low operating costs: It can fully utilize the water supply pressure of the municipal pipeline network, adjust the difference and supplement, without generating negative pressure, and can save 30% -90% energy compared to traditional water supply equipment. Power outages can also maintain the water pressure and supply of the municipal pipeline network.

　　3. High degree of intelligence, simple operation, and labor-saving: The device is controlled by a fully automatic intelligent controller, which adjusts itself according to the user's water consumption and the tap water pressure in the pipeline network. And it adopts a human-machine interface (text, numbers) display, allowing customers to more intuitively see the operation status of the equipment.

　　4. Environmental hygiene: The equipment operates in a fully enclosed manner, completely eliminating secondary pollution of the water source.

　　5. Complete protection functions: It has automatic protection functions such as overload, short circuit, overvoltage, undervoltage, phase loss, overcurrent, short circuit, and water shortage. Can perform signal alarm, self check, fault diagnosis, etc. in abnormal situations.

　　6. Small footprint and easy installation: The entire equipment consists of only one set of water supply control cabinet, non negative pressure stabilizing tank, and water pump unit, making installation very simple and convenient.

　　7. Extend the service life of the equipment: It can reliably achieve soft start for multiple pump units, avoiding impact on the power grid and pipeline network, and rotating them alternately, greatly extending the service life of the water pump and motor. The lifespan of the equipment can be extended by more than three times.
