High end residential areas, villas, schools, hospitals, offices, high-rise residential areas in large and medium-sized cities, apartments, office buildings, office buildings, hotels and other buildings with low environmental requirements, no noise, no vibration, small footprint, and high configuration for daily and domestic water use.

1. Save investment: This equipment does not require water storage facilities such as pools or tanks, nor does it require a dedicated pump room, saving floor space and reducing construction costs.
2. Ultra quiet advantage: This device has advanced anti vibration and noise reduction functions, and operates smoothly with ultra quiet operation. There is no noise pollution such as water hammer or motor operation, and the sound is controlled within 30 decibels.
3. Efficient and energy-saving: This equipment can be directly connected in series with the tap water pipeline network, fully utilizing the pressure of the municipal water supply pipeline network. Based on this, the equipment only compensates for the difference between the inlet pressure of tap water and the required pressure. When the tap water pressure meets the requirements, the equipment stops working and is supplied directly by the municipal pressure. Compared with ordinary water supply equipment, it can save 30% -90% electricity.
4. Power outage and continuous water supply: When the power supply line is cut off, it can automatically switch to municipal tap water pressure supply to maintain the original pressure of the tap water network.
5. Environmental protection and hygiene: The motor adopts a fully stainless steel shielded water filled motor, and uses water lubricated bearings that are advanced in the world today, without the need for grease. Water lubrication, water circulation, and water cooling avoid secondary pollution of water. Truly achieve full food grade stainless steel configuration.
6. Non negative pressure water supply: This device has the function of protecting the municipal pipeline network, and will not cause negative pressure to the municipal tap water pipeline network during the direct connection and pressurized operation of water intake with the municipal pipeline network. Due to the fluctuation of pressure in the municipal pipeline network with the increase or decrease of users, when the pressure in the municipal pipeline network drops to the warning pressure, the pressure holding system of the equipment will automatically detect the signal and transmit it to the electrical control system, causing the pump group to reduce or stop suction from the municipal pipeline network, thereby ensuring that the pressure in the municipal pipeline network is not disturbed.
7. High degree of intelligence: The device adopts an internationally advanced computer system to sense and transmit pressure signals, ensuring accuracy and correctness; And it can achieve fully automatic intelligent control, with functions such as manual/automatic switching, timed rotation of main and auxiliary pumps, pressure adjustment, constant voltage, high and low voltage protection, under phase protection, leakage protection, overload protection, overheating protection, water shortage and pressure loss protection, water leakage detection compensation, no water parking, instant trip protection, etc. It is equipped with RS485 bus interface for visual remote adjustment, monitoring and maintenance.
