Abstract

A universal pump coupling system that allows various style submersible pumps to be mounted to a pump mounting frame assembly to be used interchangeably within a single pump station system. The universal pump coupling system comprises a submersible pump holding device and universal guide rail assembly for use in both submersible and converted dry pit pump stations that allow numerous brands of pumps to be utilized in a single interchangeable system. The universal pump coupling system is particularly suitable for conversion of wet well/dry well pump stations to a single wet well pump station.

Claims

1. A universal pump coupling system, comprising:

a submersible pump having an inlet and an outlet;

a frame assembly supporting said pump removably mounted thereto, said frame assembly comprising a base plate having an opening therethrough in flow communication with said pump inlet, said base plate including a guide means formed therein and having a plurality of legs attached to the bottom thereof for supporting said base plate, said base plate having at least two support members extending upwardly for supporting a top plate having a guide means formed therein alignable with said guide means of said base plate;

a guide rail defining a vertical longitudinal axis, said guide rail being complementary sized and shaped for slidably engaging said guide means of said top plate and said base plate, said guide rail being secured to a lift station wall by holding means;

a flexible discharge conduit removably attachable to said pump outlet; and

means for lifting said frame assembly removably secured to said top plate for raising and lowering said frame slidably engaging said rail guide.

2. The universal pump coupling system of claim 1, wherein said frame is designed to hold said submersible pump in a fixed position with its discharge outlet angled outwardly from the lift station wall at a range of about 45 degrees to about 135 degrees.

3. The universal pump coupling system of claim 2, wherein said frame is designed to hold said submersible pump in a fixed position with its discharge outlet angled outwardly from the lift station wall at about 90 degrees.

4. The universal pump coupling system of claim 1, including an adapter for connecting said submersible pump outlet to said flexible discharge conduit, said adapter providing a means of orienting said pump outlet in a selected position.

5. The universal pump coupling system of claim 4, wherein said adapter forms an elbow.

6. The universal pump coupling system of claim 1, said pump outlet and said flexible discharge conduit being connected together by a quick disconnect assembly.

7. The universal pump coupling system of claim 1, wherein said flexible discharge conduit comprises a high strength ribbed suction hose.

8. The universal pump coupling system of claim 1, including:

a 90 degree elbow connecting at least one horizontal section of fixed discharge pipe to said flexible discharge conduit, a check valve connected to said fixed discharge pipe, a flowthrough valve connected to said discharge pipe, and a "T" or "cross" pipe connection connected to a receiving force main.

9. A universal pump coupling system, comprising:

a submersible pump having an inlet and an outlet;

a frame assembly supporting said pump removably mounted thereto and positioning said pump outlet from a wall, said frame assembly comprising a base plate having an opening therethrough in flow communication with said pump inlet, said base plate including a slotted guide means formed therein and having a plurality of legs attached to the bottom thereof for supporting said base plate, said base plate having a plurality of support members extending upwardly for supporting a top plate having a slotted guide means formed .therein alignable with said slotted guide means of said base plate;

an "I-beam" shaped fiberglass guide rail defining a vertical longitudinal axis, said guide rail being complementary sized and shaped for slidably engaging said guide means of said top plate and said base plate, said guide rail being secured to a lift station wall by holding means;

a flexible discharge conduit removably attachable to said pump outlet;

a pump adapter with a quick connect for connecting said flexible hose with said pump outlet; and

above ground fixed discharge piping and valving with a quick connect for connecting said fixed discharge piping with said flexible hose;

friction reducing material lining said guide means of said top plate and said base plate;

electrical power and sensor means in electrical communication with said submersible pump, said electrical and sensor means in electrical connection being electrically connected with a panel board by cords having twist lock plugs; and

means for lifting said frame assembly removably secured to said top plate for raising and lowering said frame slidably engaging said rail guide.
