TD single-stage pipeline circulating pumps, with standard motor and mechanical seals The structure of these products is less susceptible to the influence of impurities in the pumped liquid than similar types of products, the product is designed to be pulled out of the top of the dismantling form, which can be carried out without affecting the pipework system in the case of pump maintenance. Among them, TD32-TD150 calibre products are of extended shaft structure, and TD200-TD300 calibre products are of dismantling structure, which adopts assembled mechanical seal, and there is no need to dismantle the motor when replacing the mechanical seal.
The motor is a fully enclosed, air-cooled two- and four-pole standard motor.
Protection grade:IP55
Insulation class:F
Standard voltage:50Hz:1x220-230/240V
3x200-220/346-380V
3x220-240/380-415V
The products are suitable for conveying thin, clean, non-erosive, non-flammable and explosive liquids that do not contain solid particles, fibres or have physical and chemical properties similar to those of water. The use of viscous or dense liquids will result in a drop in the characteristic curve of the pump and an increase in energy consumption.
Maximum working pressure: 12 bar for conventional type; 16 bar for special type.
Temperature of liquid:-15℃ to 110℃.
Ambient temperature: up to +40°C
Altitude: up to 1000m
Direction of rotation: clockwise (motor blade end looking down)
