Pump head material:Cast iron/ Brass/Stainless steel
Wire:100% cooper wire
1.Efficient & energy-saving
2.Permanent magnet fequency conversion
3.Constant pressure water supply
5.Quiet& low vibration
6.Shielding without leakage
With stainless steel shield housing .completely separate the water and coil windings , no mechanical seal need ,no leakage,with high tensile porcelain bearing and shaft ,directly water cycle between stator and rotor & stator to cool the system and lubricate the bearing and lower the noise ,30 thousand hours long servie life with easy maintentance .with hall induction principle flow sensor ,high sensitivity and low fault .
For domestic hot water system such as mix water under-floor heating system, air energy hot water circulation system ,solar hot water circulation system and family cold &hot water pressurization circulation,etc.
