Abstract

A water pump assembly comprises an electric water pump, a suction-intake arm assembly, a discharge arm assembly, and a chassis configured to dampen vibrations generated by the electric water pump during operation. The electric water pump includes a pump motor, an inlet port, and an outlet port. The suction-intake arm assembly is connected to the inlet port, and the discharge arm assembly is connected to the outlet port. The chassis includes a baseboard and a yoke. The baseboard includes one or more vibration isolators on an underside thereof. The yoke includes a first opening configured to fit about a portion of the electric water pump, a second opening configured to support one end of the suction-intake arm assembly, and a third opening configured to support one end of the discharge arm assembly.

Claims (20)

1 . A portable water pump assembly comprising:

an electric water pump configured to move water, the electric water pump comprising a pump motor, an inlet port, and an outlet port;

a suction-intake arm assembly connected to the inlet port;

a discharge arm assembly connected to the outlet port; and

a chassis configured to dampen vibrations generated by the electric water pump during operation, the chassis comprising a baseboard and a yoke;

wherein:

the baseboard includes one or more vibration isolators on an underside thereof; and

the yoke comprises a first opening configured to fit about a portion of the electric water pump, a second opening configured to support one end of the suction-intake arm assembly, and a third opening configured to support one end of the discharge arm assembly.

2 . The portable water pump assembly of claim 1 , wherein the yoke further comprises a tab extending from a bottom edge of the yoke, and the baseboard includes a slot configured to receive the tab of the yoke.

3 . The portable water pump assembly of claim 1 , wherein the first opening of the yoke is lined with an elastomeric material that dampens vibrations generated by the electric water pump during operation.

4 . The portable water pump assembly of claim 1 , wherein the first opening of the yoke is lined with a length of elastomeric material that dampens vibration generated by the electric water pump during operation, and the length of elastomeric material includes a longitudinally extending groove configured to receive therein an inner edge defining the first opening.

5 . The portable water pump assembly of claim 1 , further comprising at least one elastomeric bushing positioned between a top side of the baseboard and an underside of the electric water pump.

6 . The portable water pump assembly of claim 5 , wherein the at least one elastomeric bushing is a hollow cylinder made of an elastomer.

7 . The portable water pump assembly of claim 1 , wherein:

the suction-intake arm assembly comprises an elbow fitting connected to the inlet port of the electric water pump, an inline filter configured to filter water being drawn into the electric water pump, and a hose adapter to which a hose can be attached; and

the discharge arm assembly comprises an elbow fitting connected to the outlet port of the electric water pump and a hose adapter to which a hose can be attached.

8 . The portable water pump assembly of claim 7 , wherein the second opening of the yoke is configured to fit about the hose adapter on the suction-intake arm assembly, and the third opening of the yoke is configured to fit about the hose adapter on the discharge arm assembly.

9 . The portable water pump assembly of claim 1 , further comprising a pair of handles positioned on opposite ends of the baseboard.

10 . The portable water pump assembly of claim 9 , wherein each of the pair of handles includes a pair of spaced apart legs extending from a square bend.

11 . The portable water pump assembly of claim 1 , further comprising a power supply that includes an electronic circuit contained within an electronics enclosure, wherein the electronic circuit comprises a printed circuit board configured to protect the electric water pump from overcurrent, the printed circuit board comprises an inrush current limiter and a removable fuse, the inrush current limiter is configured to prevent an EMF surge from damaging the removable fuse.
