Frequency Conversion Cold And Hot Water Circulation Pump 25PBG-6-HB-N (A)

Production Introduction:
With stainless steel shield housing, completely separate the water and coil winding; no mechanical seal need, no leakage; with high tensile ceramic bearing and shaft, directly water cycle between stator and rotor to cool the system and lubricate the bearing and work quietly; 30 thousand hours long service life with free maintenance. The energy saving function that max power is 100W and min power is 40W of conventional models but the max power is 45W and min power 5W only of constant pressure frequency conversation models, which can be saving the power 60%, with manual, automatic and automatic save electricity at night function.

Features:
1. Energy saving & high efficiency
2. Permanent magnet frequency conversion
3. Constant pressure water supply
4. No noise without vibration
5. Multi-protection
6. Shielding without leakage
7. Full seal, Moisture-proof design
