TPD25-6S - Circulation Pumps

TPD25-6S/180​

Product Description

TPD contains two parts: a hydraulic section and a motor (with a wet rotor). The hydraulic section contains a pump housing, and impeller while the motor includes a stator, rotor, cartridge, and air-venting nut. The pump does not use a mechanical seal. The stator and rotor are sealed with a cartridge made of stainless steel and two heat-resistant rubber rings, which ensure no leakage. Lubrication of bearings and cooling of the motor by the inner circulation of the pumped liquid. It can be used in single pipe or double pipe heating system. It also can be used in apartments, villas, cooling, air-conditioning, boilers and solar systems etc.

Application
  • Hot water circulation for all heating systems.
  • Industrial circulation systems.
  • HVAC systems.
  • Chilled water systems
Key Features
  • Low noise operation.
  • No leakage.
  • Ecological safety in operation.
  • Easy installation and reliable operation.
Material of Construction
  • Pump housing: Cast Iron/Stainless Steel/Cooper
  • Impeller: Plastic
  • Shaft: Ceramic / Stainless steel
  • Bearing Base: Stainless steel
  • Bearing: Ceramic/ Baptist antimony graphite
  • Connection: Cast iron / Stainless steel / Copper

Pump with Cast iron housing is widely used for delivering water for room heating. 

Pump with Bronze housing is largely used in the floor heating system.
