PBG Series Energy Efficient Wet Rotor Pump for Wall Mounted Boilers

The hydraulic module of the gas wall-hung boiler incorporates a specialized pump with an integrated self-venting mechanism. This system continuously detects and expels trapped air from the water circuit, ensuring optimal thermal efficiency in both heating and cooling modes.

Product Description

This specialized pumping solution for hydronic systems incorporates a three-phase air removal process: centrifugal separation, microbubble coalescence, and positive displacement venting through a spring-loaded automatic valve. The wet rotor configuration immerses all rotating components in the process fluid, creating a self-lubricating system that eliminates traditional maintenance requirements. Critical materials include an aluminum oxide ceramic shaft, Noryl end shields, and FDA-compliant EPDM seals suitable for potable water applications. Performance specifications indicate optimal operation with fluids having kinematic viscosity between 0.8-1.2 mm²/s at 20°C, with strict prohibitions against glycol concentrations exceeding 40% or liquids containing fibrous contaminants. Unique safety features include thermal overload protection and dry-run prevention circuitry, making these pumps ideal for unattended operation in residential heating systems.
