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.

Pressure fluctuation propagation of a pump turbine at pump mode under low head condition

Pressure fluctuation at the vaneless space and vanes passages is one of the most important problems for the stable operation of a pump turbine. The fluctuation appears in any operating condition. Much research has been done on the pressure fluctuation of hydraulic machinery. However, the details of pressure fluctuation propagation of the pump turbine at the pump mode have not been revealed. The modern pump turbine with high water head requires the runner to be “flat”, which would induce pressure fluctuation more easily than the low head pump turbine. In this article, a high head pump turbine model is used as the research object. As the pressure fluctuation at off-design point is more serious than at the design point, the low head condition is chosen as the research condition. Pressure fluctuation at the vaneless space and vanes passages is predicted by the computational fluid dynamics method based on k- shear stress transport model. The experiment conducted on the test rig of the Har...

How much is the stainless steel water pump?

We are very concerned about the price of the stainless steel centrifugal pump? How much money of stainless steel pump, in fact, this has a great relationship with product quality,some stainless steel pump like Grundfos,the price is higher, the quality is good. But there are also some stainless steel water pump,like Gelaili pump,the quality is good, but the price is not so high,it’s like buying a steak with the cabbage money. There are some small factories, the quality of their water pump production is not stable, the user experience is very poor, the price is very cheap, but in the process of using, maintenance costs have far exceeded the saved money when the pump was brought down. Therefore, how much is the stainless steel pump, really depends on the quality of the product, there is no enterprise willing to do business at a loss. How much is the stainless steel pump, stainless steel pump manufacturers and production experience affected price.Grundfos pump manufacturing history, c...

Difference between suction stroke and lift head of water pump

Pump self-priming capacity is also called maximum self suction height.It is the maximum height at which the water is pumped (the vertical distance between the pump and the the liquid surface to be pumped) without fill in water into the pump tunnel. General water level is lower than the location of the pump, you need to pump self-priming capacity.For example ,if we need to pump water from a river ,we will not plan pipe first,so we need a pump which has self-priming capacity. Or we need to pump some corrosive liquid,we can not fill water into the water pump tunnel. Some centrifugal water pumps do not have self-priming capacity,they need to fill in water at first time of using. The pump lift is the height that pump can lift water up.We usually expressed in H,the the unit is meter. The lift of the centrifugal pump is based on the center line of the impeller.The lift Consists of two parts,first is the vertical height from the center line of the pump impeller to the surface of the water s...
