TPDF Vertical Multistage Canned Motor Pump

TPDF is a centrifugal pump with pump and hermetically sealed electric motor mounted on single shaft thus eliminating the mechanical seal or other sealing device. A part of the pumped liquid is by-passed through the motor, for cooling the motor and lubricating the bearing. TBDF is the ideal solution for the common problems of excessive noise, vibration, and water leakage in water pumps on the market.

Application

Transportation medium: Low viscosity, clean, non-flammable and non-explosive liquid, liquid without solid particles or fibers

· Circulation water for air-conditioning
· Cooling and freezing system
· Liquid Circulation in industrial process
· Water supply and booster for high-rise buildings

Product Features

Extremely low noise level The pump features a silent design with reduced noise levels due to the elimination of rolling bearings. Instead, it is equipped with sliding bearings, which possess low friction, excellent self-lubrication properties, and high wear resistance. This design allows for silent operation and eliminates the need for regular lubrication and maintenance of bearings.
	No seal, no leakage TPDF pump is guaranteed to be leakage-free for life, ensuring a clean and dry pump room. By eliminating the common mechanical seal (shaft seal), the pump overcomes the issue of water leakage caused by seal damage, thus maintaining a dry and clean pump environment.
Easy maintanence and longer warranty With a suspended impeller design, the pump reduces wear on graphite bearings, significantly extending their lifespan to over 40,000 hours. As a result, we offer a three-year maintenance-free guarantee, reducing operational costs and labor intensity for our customers.
	Non overload design The pump is specifically designed for air conditioning circulation systems to ensure stable operation within the full performance range without overload.This multistage pump is a perfect substitute choice for normal stainless steel TEFC multistage pump

Model selection instructions

After sales1

Users' selection shall not be limited by the performance parameters list. Parameters in the catalog are only for reference. We could design and manufacture the product according to the actual requirements. If there is a special selection beyond the sample performance parameters, please get in touch with our technical support.

If the selected model is close to performance parameters, generally standard impeller pumps and high-speed pumps are preferred. (NPSH shall meet the requirements).

If a high-voltage motor or special motor is required, please DO NOT make the foundation according to the installation dimension of the sample. Our technical support shall customize the drawings.
