TD In-line pump Introduction
The type TD pumps are single stage in-line centrifugal pumps, equipped with standard motor and mechanical seal. Comparing with other pumps in similar structure, these pumps are less accessible to the impurity in the liquid.

TD In-line pump NPSH
To avoid the cavitations, and lessen the liberation and noise, you are suggested to adopt NPSH in table 2, to make sure that the pumps are under optimal operation condition. The data in the sheet are relative pressure(Bar), which can be read on manometer at the inlet side of the pumps.

TD In-line pump 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 degree-120 degree
Max. Pressure: PN16

TD In-line pump Installation requirements
Some detailed requirement of installation is as below, 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 pipeline cannot 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(see 2-A).
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 40degree.
5. If the pumps are installed outdoors, there should be covers to rotect electric components from water.
6. For 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)
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 1.3*pump weight shall be adopted. (See 2-c)
8. Pumps with bases or without bases are both available for customers requirements. (See appendix 1 for base dimensions).
