Flange connector
First Claim
1. A pump flange comprising:
- a flange blank having a first face adapted to be connected to a pump housing, and a second face adapted to be connected to a fluid conduit;
a central bore extending through said flange blank adapted to permit fluid flow;
a recess formed in said flange blank, concentric with said central bore, said recess having a first diameter;
said recess including a plurality of apertures adapted to allow for the passage of fasteners to secure said pump flange to the pump housing;
an insert plate adapted to be positioned within said recess, having a central bore extending through said insert plate, and a sealing member positioned between said insert plate and said flange blank adapted to seal said insert plate to said flange blank to prevent fluid leakage from the pump.

Abstract
This invention is directed to a novel multi-piece flange connector used for connecting a pump housing to a fluid conduit. The pump flange is comprised of a flange blank, an insert plate, and a seal. The flange blank is adapted to be connected to the housing of a pump and includes a central bore adapted to allow the passage of fluid. The flange blank also includes a recess surrounding the bore that is adapted to accept the insert plate and the seal. The flange blank is connected to the pump housing by the use of bolts or other fasteners that pass through apertures in the flange blank beneath the insert plate. The insert plate includes a seal member that prevents fluid from the central bore from leaking outside of the flange.

13. A pump flange for mounting to a pump comprising:
-
a base member having a first mounting surfaced adapted to be connected to the pump and a second mounting surface adapted to be connected to a fluid conduit;
said base member including a bore passing therethrough;
a recess formed in said second mounting surface and surrounding said bore, said recess includes a plurality of apertures adapted to accept fasteners to secure said base member to the pump;
a plate member positioned within said recess and adapted to engage the fluid conduit, said plate member including a bore passing therethrough;
a seal attached to said plate member and adapted to create a seal between said base member and said plate member to prevent fluid loss from said bores. - View Dependent Claims (14, 15, 16, 17, 18)
