JB single stage pipeline centrifugal pumps equipped with standard electric motor and mechanical seal include ISG centrifugal pump, IRG centrifugal pump, YG centrifugal pump etc.
Comparing with other pumps in similar structure,these pumps are less accessible to the impurities in the liquid.
Application:
The pumps are applicable for clean, attenuate, non-corrosive, non-flammable and non-explosive liquid, which shall not contain any solid grain and fiber that might damage the pump mechanically or chemically. The detailed requirements on the liquid are listed as follows,if the liquid viscosity or density is beyond the required level, the performance curves will descend and energy consumption will be in creased.
Liquid temperature: -15℃~+110℃
Max pressure: Normal:PN12 Special:PN 16
The pump can be applied to kinds of water conveying system, such as domestic water system, industrial water system, cooling system, district heating system etc.
1. Main circulation pump
2. Mixed circulation system.
3. Mixed flow pump
4. Gas refrigerating machine
5. Some flow filters
6. Pressure leveling system
7. Domestic hot water circulation system
Additional,it can be used in chemical industry, pharmaceutical industry, food industry and so on.
1. Material conveying.
2. Pressure increasing
3.Mixed circulation system.
Installation requirements:
The concrete request is as follows
1. If the system pipeline can support the pumps,pumps with 2.2KW motor power(including 2.2KW) can be hung in line. If the system can not support the pumps or the pump motor power is higher than 2.2KW, the pumps must be installed in brackets or base.
2. Pumps with motor power lower than 2.2KW(including 2.2KW) can be installed horizontally or vertically to the pipeline. Pumps with motor power higher than 2.2KW can only be installed vertically to the pipeline.
3. The pump installation shall not allow the system pipeline tensile force to be transferred to the pump body.
4. The pump should be installed in the environment with sufficient cooling and cooling air shall not be above 40℃.
5. If the pumps are installed outdoors, there should be covers to protect electric components from water.
6. For the convenience of maintenance, there should be enough space above and below the pumps, minimum 300mm shall be kept for pumps with motor power lower than 5.5KW, and minimum 1000 mm for pumps with motor higher than 5.5KW(including 5.5KW)
7. To prevent noises and vibration and ensure the best operation, anti-vibration base shall be used in installation. Generally, cement base with the weight equal or bigger than 1.5x pump weight shall be adopted.
9. Pumps with bases or without bases are both available for customers requirements.
