PBG Series Domestic Heating System Pump for Clean Water Circulation

The pumps are assembled in the hydraulic module of the gas wall hung boiler for heating and cooling system, An integrated air venting system of the pump can automatically deposits the air out of the water.Its model is 15PBG-6(A2).

Product Description

The gas-fired wall-mounted boiler's hydraulic module incorporates high-efficiency wet rotor circulation pumps specifically engineered for dual heating/cooling applications. These innovative pumps feature an intelligent auto-venting mechanism that continuously separates and evacuates air bubbles from the liquid medium through a patented multi-stage separation process. Utilizing a completely flooded rotor design, the system achieves maintenance-free operation as the process fluid itself provides both cooling and lubrication to the precision bearings. Key components include a corrosion-resistant stainless steel rotor assembly, epoxy-coated stator windings, and a reinforced polymer venting chamber with automatic float valve. Strictly designed for pH-neutral (6.5-8.5), particle-free (<50 micron) heat transfer fluids, these units are expressly prohibited from handling petroleum derivatives or combustible liquids due to their non-explosion-proof construction.

FAQs

1.Q：Any installation tips?
A：Mount horizontally, add inlet filter, prevent cavitation.
2.Q：Can pumps be installed vertically?
A：Yes, but verify motor cooling method (some require forced air).

3.Q：Is regular maintenance required?
A：Annual seal/bearing check; no complex maintenance.
