Armstrong 110108MF-675 Raypak 1 Boiler Header Pump

Description

Restore boiler-header circulation with Armstrong 110108MF-675 Raypak 1, a pump-less-volute assembly for high-temperature commercial boiler service. The package includes the motor, bearing assembly, and impeller while allowing a compatible existing volute to remain in the piping. Its 1/3 HP single-phase motor and 115 V supply suit targeted replacement work. Confirm the volute condition, shaft fit, and impeller clearance before installation.

The three-piece maintenance-free design uses a 4-3/8-inch non-ferrous impeller and Viton seal rated for temperatures up to 300°F. The supplied data identifies the base circulator as a 2B 1050 AB LV and lists Raypak, Teledyne, Laars, and Lochinvar equipment as target boilers. Flow, head, amp draw, dimensions, weight, and bolt measurements were not supplied, so verify the existing casing and system curve before startup.
