ISG series vertical pipeline cooling water centrifugal pump

    ISG series single stage single suction pipeline centrifugal pump is designed on the base of

    domestic execellent water power model and the performance parameter of  IS series cen-

    trifugal pump.

    ISG Series centrifugal pumps are designed for such as hot water pump and corrosion resi-

    stance pump and oil pump for  the different temperatures and liquids. The pump has good

    performance of reliable operation and high effeciency and little noise etc.

ISG series vertical pipeline cooling water centrifugal pump

  1,Compact structure,horizontal structure ,beautiful appearance and less area of occupied land,

      which comparing with the ordinary ones is reduced by 30%;

  2,Stable running ,low noise,high concentricity of assembly.By the straight joint between motor

     and the pump.the moddle structure is made simplified ,thus enhancing the running  stability ,

     making the impeller of a good balance of moving -resting ,resulting in no vibration during run-

     ning and improving the environment of usage .

  3, No leakage .a mechanical seal of antisepticcaarbide alloy is ued for the shaft sealing so as to

     let rid of the serious leakage of the fillings of centrifugal pumps and ensure the operating place  

     clean and neat ,

 4,Convenient service .


ISG series vertical pipeline cooling water centrifugal pump

 1.ISG series vertical pipeline centrifugal pump is used to transport the water and other liquid

     similar to the water in physical and chemical characteristic. It is widely used for the drainage

     in industry and city, booster and water supply for high-building, irrigation in garden, booster

     in fire fighting, transporting from along distance, water circulation in circultion system etc.

     Working Temperature<80oC.

 2. IRG series vertical hot water pump is suitable in metallurgy, chemical industry, textile, timber

     processing, paper making and booster and circulating for high temperature and hot water in

     hotel.

     Working temperature <240C.

 3. IHG series vertical pipeline chemical pump transports the liquid which is corrosive an without

     solidgrain and similar to water in viscosity. It is suitable in petroleum, chemical industry,metal-

     lurgy, electric power, paper making, food an   pharmacy and synthetic fibre etc.

 4. IHG series stainless steel chemicalcentrifugal pump with explosion-proof is suitable to trans-

     port the flammable  chemical liquid.


Q:What is the lift of diaphragm pump?
Diaphragm pump lift is different from the centrifugal pump, refers to the diaphragm pump can raise the height of water, the unit is meters water column. Lift depends on the size of the outlet pressure, the pressure per kilogram is equivalent to 10 meters height
Q:Is vane pump good or gear pump good?
The main working parts of vane pump is provided with a plurality of sliding vane rotor, when the rotor rotates, the eccentric configuration of stator cavity contour or rotor, blade sliding slot in leaves due to volume changes, resulting in the suction effect. The similarities are: 1, rotary type positive displacement pump has self-priming ability, but are not allowed to do; 2, with continuous flow pulsation, but also have flow and pressure; 3, the theory of flow is determined by the working parts of the size and speed, has nothing to do with discharge pressure; 4, rated discharge size, pressure and working parts mainly depends on the pump speed is independent of the sealing parts and bearing capacity; differences: 1) gear pump structure is more simple, reliable, low price; vane pump has complicated structure and high manufacturing precision parts, the blade is easy to get stuck, more sensitive to the oil clean degree and viscosity.
Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?
The operating pressure of the hydraulic system depends mainly on the load. Generally speaking, the working pressure of the hydraulic system means the highest working pressure of the system. If the pressure is higher than the value of the equipment, the relief valve works to relieve pressure. The actual working pressure of the hydraulic system is determined by the load, which refers to the actual pressure of the hydraulic oil and can be read directly from the pressure gauge. The pressure increases with the increase of the load. You Li's balance can know: the thrust of the cylinder = the load, the thrust of the cylinder = the working pressure of the hydraulic oil, the working area of the cylinder, the working pressure = the load / the area of the cylinder.
Q:If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?
First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.
Q:Why can't the centrifugal pump pump the vacuum?
Condition:The pump shell must be filled with liquid under certain installation height and running without leakage.What is the phenomenon of centrifugal pump? What harm does it have? How to eliminate?)
Q:Fire pump and shower pump flow head selection, high resolution.
Selection of flow head of fire pump and spray pump:1, the volume is greater than 5000 is less than 10000, the minimum water consumption of indoor fire hydrant is 10L/s
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
Q:The distance from the pump button to the ground
After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.
Q:Harm of air pump and pump
If the liquid is not full, this situation is generally the suction pipe or pump shell leakage, then easy to cause cavitationHit the pump for centrifugal pumps, centrifugal pump is recommended to start closed, the discharge valve closed, starting is in the state of pump
Q:What are the problems that should be paid attention to when using vacuum pumps?
(8) in the process of running the pump, the bearing temperature shall not exceed the ambient temperature 35C, and the maximum temperature shall not exceed 80C.(9) if the abnormal sound of the vacuum pump is found, the reason should be stopped immediately.(10) vacuum pump to stop using, first shut down valve, pressure gauge, and then stop the motor. (11) vacuum pump in the first month of work, 100 hours after the replacement of lubricating oil, oil every 500 hours after the change.(12) adjust packing gland regularly to ensure the normal condition of drip in packing room. (13) regular inspection of shaft sleeve wear, larger wear should be replaced in good time.
