2.Tightness:the pump does not use mechanical seal. Stator and rotor are  sealed with shield cover made of stainless and two heat-resistant rubber rings, which makes no leakage.

3.Lubrication of bearings and cooling of motor by inner circulation of pumped liquid.

4.Insulation class H, up to 180 celcius working temperature, motor fixed with thermal protector, three speeds to match the best working point of system.



The pump is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. Speed no: The pump has 3-step speed selector. 

Shinhoo circulators have over 80% components self-produced, with own workshops for motor, rotor, injection parts, shielding cann etc.
