Why is the stainless steel centrifugal water pump very quiet?

Most of the time when a electric pump started, it makes a buzzing sound,the normal cast iron water pump 's sound is about 40db.
If the water pump works ,it is affect our rest and sleep.so pump station usually build far away from resident house.some pump station even were designed and built under ground.
The sound of water pump runing has two prats,one is because the motor drive the pump,then there is sound made by electric motor.the other is come from the pump tunnerl,the impeller drives the water, the flow and impeller has friction,the sound comes out.
Gelaili GDL series water pump and HL series water pump are made of stainless steel,they are very quite,they run only 12db,only slightly larger than the leaves blown by the wind.
Why stainless steel water pump is so quiet?
Due to rough surfaces of cast iron water pump,greater friction with the flow was caused.But the stainless steel impeller and tunnel is very smooth,the friction is very small,so the stainless steel water pump is so quiet that you can not notice it is exist.
Besides,these pumps are all use NSK bearing,so when you operate the water pump,it is very low sound.
Gelaili stainless steel water pump,protect your sleep time,keep you away from noisy,leave you only peace and quiet every night.
Gelaili pump industry supply good pumps with 50 years manufacture experience.
We provide aquarium water pump,shower pump, coolant pump,dirty water pump,dewatering pumps,booster pump,ro booster pump and so on.

Several type of pumps for changing human life

Today we will talk about several type of water pump ,which changes our life. 1, Booster pump :The last decades,people who lives in high building can feel pains caused by the low water pressure,especially in rush hour.But now,the convenience booster pump takes to us become a part of our life. We nearly forget it exist.In nowadays,building is taller and taller,but even on the top of the high cloud bulding,the flow of water is also very stable and strong. 2,Ro booster pump:As ro technology developed,ro booster pump step into our daily life,since the pump appeared ,make water clean and safety is not a hard work,this type of pump helps a lot of people drink clean water,avoid disease,especially some people who is required only drink purified water,do not need to pay too much money to buy purified water,we can get it anywhere.Even in desert,bottle water can be brought easily.some sweet water purified by sea water,how magical pump is it? 3, Aquarium water pump ,fishes which we can see on...

Causes of Electric Motor Burning by Water pump

1. First, find out whether the motor burns the bearing (mechanical fault) or the coil (electrical fault). If it is the fault of burning coil, it is mainly caused by overcurrent, sometimes too high or too low voltage will also cause the coil to heat and short circuit, so check that the voltage when running is too different from the rated voltage.There may be several reasons for over-current short-circuiting: A. the equipment is overloaded to make the motor run for a long time at rated or over rated current. In particular, the starting current of the motor is 3-5 times that of the rated current. Therefore, we should try to avoid running with load or full load when starting the equipment (mainly depending on the matching allowance of rated current and normal operating current of motor). B, the motor works in a wet working environment. The insulation of the coils should be checked before the motor starts. The insulation requirements of different voltage grades are also different. May r...

A modification project for dirty water pump sealing

The mechanical seal of a sewage circulating pump in a factory has been seriously leaking since it was put into operation.It can not be operated normally after several times of replacement.The leakage of wastewater containing organic matter, acid, alkali, salt, etc.It has resulted in varying degrees of corrosion to the equipment,and caused pollution to the environment, the loss is more serious.the dirty water pump leakage become a problem affecting the production of the factory. After a thorough renovation of the sealing structure of the dirty water pump, good results have been achieved. Let's talk about the modification design, we will know better about how to make dirty water pump to work better. Field analysis This dirty water pump is a cantilever centrifugal pump,Internal rotation, internal leakage, single spring, non - balanced carbide cemented carbide mechanical seal.After disassembly, it is found that the sealing device is seriously damaged and the friction material ...
