Encompass 511-405-113 Circulator Pump

Product Description

The ENCOMPASS 511-405-113 is a hydronic circulator pump used in hot water heating systems to move heated water through the distribution loop. Circulator pumps maintain consistent flow between the boiler and terminal heating units such as baseboard radiators, fan coils, or radiant floor loops. This unit is sourced through Encompass Parts and Accessories, positioning it as a service replacement component for Weil McLain boiler systems. Licensed plumbers and HVAC technicians handling hydronic heating service and maintenance are the primary installers of this part.

This circulator is applicable to residential and light commercial hydronic heating installations where a Weil McLain boiler serves as the heat source. It is suited for closed-loop hot water distribution systems requiring reliable, continuous circulation to maintain system efficiency and comfort. It is commonly encountered during boiler service calls, seasonal startup inspections, or emergency heating repairs where the original circulator has failed or degraded.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician familiar with hydronic heating systems. Before removing the existing circulator, shut off power to the boiler at the disconnect and close the isolation valves on both sides of the pump to prevent system drain-down. Follow all applicable local plumbing codes and manufacturer guidelines when reinstalling and restoring system pressure. After installation, bleed air from the system as needed and verify proper flow and pressure before returning the boiler to service.
