G HLK horizontal stainless steel ro booster pump

G-HL/HLK horizontal multistage centrifugal pump is a small type stainless steel pump, can be used at home and industry,as it is small size, easy install and quite noise booster pump, a lot of people choose use it at home and hotel,restaurant as shower pump, it can rise water pressure.
Besides, industry also choose this pump to transport drinkable water such as ro booster pump,a lot of food and medical industry use large quantity of this kind of pump.
Some industry choose G-HLK pump as aquarium water pump,to pump fish water .
So G-HL/HLK horizontal multistage centrifugal pump be produced in a lot of usage,widely used.
Gelaili pump industry focus on advanced pump manufacture,supply good quality water pump.

The advantages of the stainless steel centrifugal pump

The stainless steel  centrifugal water pump  can be used to convey various medium from tap water to industrial liquid at different temperature with different flow and pressure.the stainless steel  centrifugal water pump  can be used to transport the liquid,which PH Value is 5-9,the liquid can be slightly alkaline water,take off a mineral water,distilled water,swimming pool water,chloride liquid, they are anti-corrosion pumps. Stainless steel  centrifugal water pump  can last for a long time, stainless steel gear pump because the high quality material and light weight rotating parts, the stainless steel  centrifugal water pump  life expectancy is much longer than the ordinary pump. Gelaili pump industry ,supply professional stainless steel water pump. www.jxgllpump.com

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...

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...
