TD Pipeline Circulating Pump

The TD series single-stage inline circulation pump, equipped with a standard motor and mechanical seal, is less susceptible to the effects of impurities in the pumped liquid compared to similar products.

The product features a top-pull-out design, allowing for pump maintenance without affecting the piping system. The TD125 and TD150 models are available with extended shafts and easy-to-remove designs, while the TD200 and larger models utilize an integrated easy-to-remove mechanical seal, eliminating the need to disassemble the motor for seal replacement.

Performance Curves

This product is suitable for use in clean, thin, non-corrosive, non-flammable and non-explosive liquids that do not contain any solid particles or fibers that may cause mechanical or chemical damage to the pump. Specific liquid requirements and applications are shown in Table 2 below. However, use in viscous or dense liquids will cause a decrease in pump characteristic curves and an increase in energy consumption.

Liquid Temperature: -15℃~110℃
Maximum Operating Pressure: Standard type PN12 bar; Special type PN16 bar

The product features a separable motor and pump structure, with the pump section designed as a pull-out type. All products of this type are equipped with a standard motor and mechanical seal. The motor is a fully enclosed, air-cooled standard motor, and its main dimensions conform to JB/T8680 standard.

The pump body is equivalent to a section of pipeline. During pump maintenance, the pump body can be sealed with a blind flange, thus not affecting the normal operation of the system.

The connecting flange dimensions of the product conform to GB/T17241.6 (ISO7005-2) standard, with a pressure rating of PN16.

The inlet and outlet diameters of the product conform to relevant standard dimensions.

The pump head is the device connecting the motor and pump. The seal between it and the pump body uses an O-ring.

Different products have different installation requirements, which are as follows:
1. The system piping must be able to support the pump. Pumps with motors of 2.2kW or less (including 2.2kW) can be directly suspended in the piping. If the system piping cannot support the pump, or if the pump motor power is greater than 2.2kW, the pump must be mounted on a bracket or base plate.

2. Pumps with motors of 2.2kW or less (including 2.2kW) can be installed horizontally or perpendicular to the piping. Pumps with motors above 2.2kW can only be installed perpendicular to the piping.

3. During pump installation, ensure that the tension of the system piping is not transmitted to the pump body during operation.

4. To ensure normal motor operation, the pump must be installed in an environment with sufficient cooling, and the temperature of the cooling air must not exceed 40℃.

5. If the pump is installed outdoors, a suitable enclosure must be provided to prevent water ingress or condensation on electrical components.

6. Sufficient space must be left above and below the pump for easy inspection and maintenance. 7. For pump motors less than 5.5kW, allow at least 300mm of clearance; for pump motors greater than or equal to 5.5kW, allow at least 1000mm of clearance.

8. To prevent noise and vibration and ensure optimal operating performance, the pump must be installed using a vibration-damping base. A concrete base is generally used, and its weight should be greater than or equal to 1.5 times the pump weight.

9. To meet different customer needs, TD32~TD150 products are available with and without a base plate. (See attachment for base plate dimensions)
