Description:

All spare parts are designed into standard size, the middle section is sealed by O ring and connected by bolts outside of the middle section. Metal composite wave tooth gasket can be used in special occasion.
The suction section and discharge section is generally foot mounted, and centerline mounted when the liquid’s temperature more than 150 °C.
Each type have two sets of impeller/guide vane, and the TDY pump have a wide high-efficiency zone. Changeable wear ring to seal between pump casing and impeller. Most axial forces is balanced by hydraulic balanced devices and other are balanced by thrust bearing. 
Grease lubrication or oil lubrication.

Q:Domestic pump automatic shut off the water, but also turn around, stop what happened?
What should have Water Leakage place, check all the toilet faucet is Water Leakage, Water Leakage, water heater and so on, if no problem, to check the pump, which has a check valve, when the valve is broken, can not maintain the pressure, there will be the phenomenon
Q:Relationship between power and flow of sewage pump
There is a formula for motor power = flow (m3/h) * lift head (meter), *9.81/3600/ efficiency (general sewage pump efficiency is about 55%), *1.2 (motor safety factor)For example, 10 tons of flow, lift 10 meters, how much power?N=10*10*9.81/3600/0.55*1.2=0.595. so the motor power we chose should be 0.75KW
Q:What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
The feed pump is a pump for supplying water to the boiler and maintaining the water level of the boiler. The condensate pump provides water to the deaerator after condensing the turbine and provides water for some condensate users. Vacuum pump is to maintain the vacuum of the pump, the pump is to lower the drain in a timely manner to the next level of low pump
Q:Under what circumstances should we set up fire pool and fire pump room? Is it necessary to have a building?
These facilities are available only in large public buildings.
Q:What does water flow mean?
Forehead... Flow do not understand it....
Q:About water pump selection
Domestic I do not understand, only know that you dock water, it is best to use sea water pump, or allow manufacturers to do your anti-corrosionVille, Grundfos.Lift up, I'll do it. 30m is pretty muchThe self-priming pump is OKWhich brand do you want to use? Just call them directlyLet them count it for you and then type itFirst know about yourself, generally know a power head water quantity on the line
Q:Why does the pump head decrease when the pump flow rate increases?
When the power increases to a certain extent, can not be increased, so when the flow increases, the head can only be reduced
Q:Difference between primary hot water pump and two hot water pump
A hot water pump is a water pump circulating between the boiler and the heat exchanger, and the two hot water pump is a circulating water pump between the heat exchanger and the user. That is, there is no relationship between a water pump and heating users.
Q:Should the no-load power of the pump be equal to the rated power?
Manufacturers in order to make money, the nameplate marked "1200W", in fact, the maximum power of the motor, only 750W.
Q:How to install circulating water pump for cooling tower?
This should be installed at the inlet of the cooling tower. The water at the outlet of the cooling tower is returned to the pool
