Boiler Feed Water Pumps & Condensate Pumps | Boiler Supplies Boiler Feed & Condensate Replacement Pumps Sterling 4100 G-Series Condensate Pump & Motor (With Volute)
Built with a heavy cast iron housing and brackets for durability, the G-Series uses the advanced SterlSeal ceramic seal for long service life. The motor shaft is isolated from water, with seal flush/vent provisions included. Close-coupled to a 3450 RPM motor (ODP, TEFC, or explosion-proof), the design allows motor and impeller removal without disturbing piping. Features a bronze impeller hub, stainless steel motor shaft, ¾" NPT discharge, and is rated up to 250°F. Available in ⅓, ½, and ¾ HP models.
Note: Pumps made prior to 2023 use a different impeller design. Seal kits fit all models, but 2022 and earlier units require a full new pump & motor (less volute) if replacing the impeller.
