CONDENSATE RETURN UNITS SERIES CVC AND/OR
BOILER FEED UNITS SERIES BFC & BFCE
1) Pump(s)
A single-stage coupled cast iron, bronze fitted casing, leak proof mechanical shaft seal, stainless steel large diameter corrosion resistant shaft, and bronze casing wearing. These pump(s) requirement allows handling of 2500F condensate without flashing and cavitation. The pump(s) is provided with an axial flow impeller being enclosed in a cast bronze construction. The pump(s) cast iron flanged volute has an internal cast iron baffle preventing pre-rotation of the condensate. The entire rotating assembly can be removed without distributing the discharge or return piping.

5) Mechanical Controls:
For CVC Units:
Automatic operation is provided by an internal mounted enclosed adjustable float switch assembly, for simplex (S-CVC) or two float switches or control panel with electrical alternator for duplex (D-CVC) operation.
The alternator shall: Change the operating sequence automatically after each cycle.
                                                 Provide simultaneous operation under peak load conditions.
                                                Operate the second pump automatically, should the active pump or its control fail.
