The DFMM series intelligent silent pumps feature a segmented modular design. They have a compact structure, facilitating installation and maintenance. The pump is sealed within a pipe and equipped with a submersible motor, resulting in low - running noise, which gives it unique advantages in building pressurized water supply. The product can be equipped with a dedicated pump frequency converter for variable - frequency control of the pump. To ensure safe operation of the equipment, it has built - in multiple protections such as no - flow operation protection, phase - loss protection, over - heat protection, and over - current protection.
Product Technical Parameters
Power supply: Three - phase (380 ± 5%) V
Head: 11 - 151 m
Medium temperature: Maximum water temperature 35°C
Flow rate: 4 - 60 m³/h
Rotational speed: 2850 r/min
Maximum particle diameter of medium: ≤ 0.2 mm
Product Applications
Secondary water pressurization in buildings
Renovation of pump rooms in old residential communities
Design of water supply pump rooms for refuge floors or booster water supply floors in high - rise residential buildings
Occasions with strict requirements for pump room noise
Product Features
1. Low Noise
Equipped with silent - type submersible pumps + silent submersible motors/shielded motors.
The factory - matched flow guide cover can effectively absorb noise.
2. Intelligence
The dedicated pump frequency converter has control and variable - frequency functions, and multiple frequency converters can communicate with each other.
It has protection functions such as repeated start - stop, phase - loss, over - current, and idle - running protection.
The frequency converter has a one - key function to adjust pressure and various parameters, which can be operated without professional personnel.
3. Energy - Saving
The efficiency of the pump is higher than the national standard, making the product more energy - efficient.
4. Safety and Convenience
It has a complete set of protection functions.
The wetted parts are made of sanitary - grade stainless steel, avoiding secondary pollution.
The segmented modular structure makes inspection and maintenance convenient.
Basic Working Principle
The intelligent silent pump assembles the submersible pump and the silent submersible motor in the pipeline and fixes them in the pipeline through a specific method to ensure no vibration during operation. The submersible motor is filled with antifreeze liquid inside, which lubricates the bearing. Water - cooling is adopted externally. Through precise calculation, the internal water flow of the pipeline meets the requirement of cooling the motor, thus increasing the service life of the submersible motor.
Principle of Silent Operation
Our company has conducted multiple tests and improvements on the structure and material of key components based on ordinary submersible pumps, further controlling the noise. In terms of the motor, silent submersible motors or shielded motors are used. Continuous improvements have been made to the thrust bearing inside the motor to ensure the smooth operation of the motor and greatly reduce noise. The liquid filled between the motor and the cylinder also plays a role in noise reduction. The overall structure optimization has significantly improved the product in terms of shockproof and noise reduction.
