TD In-line-Umwälzpumpe

Product Info. Introduction The type TD pumps are single stado in-linecentrifugal pumps,equpped with standard motor and mechical seal.Comparing with other pumps in similar structure,these pumps are less accessible to the impurity in the liquid.NPSH To avold the cavitations,and lessen the libration and noise,you are suggested to adopt NPSH in table 2,to make sure that the pumps are under optimal operation conition. The data in the sheet are relative pressure(Bar),which can be read on manometer at the inlet side of the pumps.Application The pumps are applicable for clean,attenuate,non-corrosive,non-flammable,and non-explosive liquid which shall not contain any solid grain and fibre that might damage the pump me chanically or chemically.The detailed requirements on the liquid is in Table 3.If the liquid viscosity or density is beyond the required level,the performance curves will descend and energy consumption will be increased. Liquid temperature : 15∼120 Max.Pressure:PN16Installation requirements Some detailed requirement of installation is as below,The concrete request is as follows: 1If the system pipeline can support the pumps,pumps with 2.2KW motor power(including 2.2KW)can be hung in line;if the system pipeline cannot support the pumps or the pump motor power is higher than 2.2KW,the pumps must be installed in brackets or base. 2Pumps 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(see 2-A). 3The pump installation shall not allow the system pipeline tensile force to be transferred to the pump body. 4The pump should be installed in the environment with sufficient cooling and cooling air shall not be above 40. 5If the pumps are installed outdoors,there should be covers to rotect electric components from water. 6For the convenience of matinenance,there should be enough space above and below the pumps.Minimum 300mm shall be kept for pumps with power lower than 5.5KW,and minimum 1000mm for pumps with motor power higher than 5.5.KW(including 5.5KW).(See 2-B) 7To 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 1.3*pump weight shall be adopted.(See 2-c) 8Pumps with bases or without bases are both available for customers requirements.(See appendix 1 for base dimensions).
