PBG Series Stainless Steel Shielded Pump for Clean Non Corrosive Liquids

The wet rotor pump installed in the hydraulic module autonomously handles air evacuation during operation. Its built-in venting mechanism uses float-actuated valves to purge air pockets, ensuring uninterrupted fluid circulation in HVAC applications.

Product Description

The modular pump system represents a significant advancement in boiler hydraulics, featuring simultaneous flow generation and air elimination in a single compact unit. Its wet rotor principle utilizes the pumped medium for both heat dissipation and bearing surface lubrication, achieved through precisely machined silicon nitride journal bearings. The automatic vent valve employs a dual-density float mechanism that responds to both macro and micro air bubbles without requiring manual adjustment. Construction materials have been carefully selected for residential heating applications, including lead-free brass volutes and food-grade sealing elastomers. Operational limitations include maximum 3.5m³/h flow capacity, 6m head pressure, and absolute prohibition against pumping liquids containing surfactants or viscosity modifiers that might compromise the self-lubricating characteristics.
