Patent ID: 8251021

Claim:
A compact assembly of a hydronic manifold with a hydraulic separation chamber and at least one end-suction type secondary loop pump, comprising: (a) a manifold having a primary loop inlet, a primary loop outlet, one or more secondary loop outlets, and one or more secondary loop inlets, all communicating with the hydraulic separation chamber within the manifold; (b) the primary loop inlet and the primary loop outlet being parallel to each other at a distance and with fittings for coupling to other hydronic components such that the primary loop inlet and the primary loop outlet will mate with other hydronic components having a mating inlet fixed to a mating outlet, the mating inlet and mating outlet being parallel to each other and conforming to the distance and the fittings; (c) each of the one or more secondary loop outlets respectively coupled to an inlet of an end-suction type centrifugal pump having an outlet in a plane that is perpendicular to its inlet; (d) wherein the manifold is configured so that, when mounted alongside a vertical wall, the assembly may be oriented so that (1) the secondary outlets and secondary inlets are directed parallel to the wall or away from the wall but not toward the wall, and (2) each secondary loop outlet and coupled pump inlet is oriented horizontally and parallel to an axis of a rotational impeller in the pump, and (3) the manifold and at least one pump are each alongside the wall such that one could mount the assembly with the manifold and at least one pump at equal distances from the wall.
