Silent water pump



Silent water pump refers to a miniature water pump with very low noise. The noise of the water pump not only comes from the operation of the motor, but also from the friction between the water and the pipe wall. Generally speaking, we call a low noise water pump a silent water pump. The design focus of a silent water pump is to reduce the generation of noise. This type of water pump adopts a special structural design, which can minimize the noise while ensuring normal operation.


Silent water pump is a new type of water pump that is efficient, energy-saving, and environmentally friendly. Its noise mainly comes from two aspects: 

1. It is generated by the power of the electric motor;

2. It is generated by friction between water and the pipe wall.


Another advantage of silent water pumps is energy efficiency. Due to its excellent design, the water pump can more effectively utilize energy during operation, thereby reducing energy waste. This not only helps to save resources, but also benefits environmental protection.


At present, most of the silent water pumps on the market are DC silent water pumps, because DC water pumps have the characteristics of long service life, no maintenance, small size, high efficiency, low power consumption, strong anti-interference ability, stable operation, and strong waterproofing, ensuring low noise during operation. Some can reduce noise to below 25dB.

Selection of silent water pumps: What are the standards for silent water pumps ?

You can choose according to the following principles.

1. Working medium at room temperature (0-70℃), simply pumping water or solution, not using both water and gas, and has requirements for flow and output pressure.

Note: The working medium to be pumped is water, non-oily, not strong corrosive liquids and other solutions (can not contain solid particles, etc.), must not have self-priming function, you can choose the following pumps:

(1). The flow requirements are not high (about 12-20 liters/min), and the pressure requirements are not high (about 8-11 kg), mainly used for water circulation, water sampling, lifting, etc., requiring low noise, long life, small size, etc., Then the optional P4520 and P6077 series;

(2). High flow requirements (about 11 to 90 liters/minute) and high pressure requirements (about 9 to 40 kg), mainly used in industries such as circulation, booster, and chiller, and do not need to work under high pressure or heavy load for a long time , you can choose P6037, P6076 and other series;

(3). It is used in the plumbing mattress industry, etc., which requires as small a volume as possible, small flow requirements and low noise (about 1-3 liters/min), and P4002, P4549 and other series are optional.


2. Working medium at room temperature (0-50℃), need to pump water or gas (may be mixed with water and gas or idling, dry running), pay attention to the performance of volume, noise, continuous use and so on.

Description: It is required to be used for both water and gas, and it can run dry for a long time without damaging the pump; it can run continuously for 24 hours; the volume is particularly small and the noise is low, but the requirements for flow and pressure are not high.

(1). Pump air or vacuum with a micro pump, but sometimes liquid water will enter the pump cavity.

(2). The micro-pump is required to be able to pump both air and water.

(3). Use a micro pump to pump water, but sometimes the pump may have no water to pump, and it is in a "dry run" state.

(4). Mainly use micro-pumps to pump water, but do not want to manually add "water diversion" before pumping, that is, hope that the pump has a "self-priming" function.


3. High temperature working medium (0-100℃), such as water circulation heat dissipation, water cooling, or pumping high temperature liquid, etc., must use high temperature type.

(1). The temperature is between 50-70°C, the water pump P6077 and high temperature medium type used in the water heater industry can be selected, and the maximum temperature resistance temperature is 80°C or 100°C;
