Portable pump
A pump for non-flammable liquids has an improved mounting for the motor which facilitates the relatively quick and easy removal of the motor from the pump. The pump has a main body which is hollow and cylindrical. A motor housing is connected to the main body by threads at a first end and has a removable end cap on its second end. The electric motor is located in said motor housing and secured when the end cap is on the motor housing. An electronics housing has a battery adapter plate, a switch, and a discharge port, and encloses wires and electronics such that the motor pumps the liquid from the end cap, through the motor housing and the main body, and out of the discharge port when the switch is turned on.
1. A portable pump for pumping non-flammable liquids, comprising:
a main body, said main body being hollow and cylindrical;
a motor housing, said motor housing being connected to said main body by threads at a first end and having a removable end cap on a second end;
an electric motor located in said motor housing; and
an electronics housing having a battery adapter plate, a switch, and a discharge port, said electronics housing enclosing wires and electronics such that said motor pumps liquid from the end cap, through the motor housing and the main body, and out of the discharge port when said switch is turned on,
wherein said motor can be removed from said motor housing when said motor housing is disconnected from said main body and said end cap is removed.
2. The portable pump as recited in claim 1 , wherein the motor is contained within a wire harness assembly, the wires from said electronics housing passing through a first end of said wire harness assembly and being terminated in terminals that can be connected to terminals of said electric motor by hand.
3. The portable pump as recited in claim 2 , wherein the pump further comprises a spacer in the motor housing, said spacer being located between a motor mount of said electric motor and said end cap such that said electric motor is secured in place when said end cap is on.
4. The portable pump as recited in claim 3 , wherein the motor mount of said electric motor comprises a plurality of flanges and said spacer comprises a plurality of slots equal in number to the plurality of flanges, and the plurality of slots of the spacer engage the plurality of flanges of the motor mount when the spacer is properly positioned.
5. The portable pump as recited in claim 3 , wherein a screen or filter fits into the spacer and can be removed or replaced when the end cap is off.
6. The portable pump as recited in claim 1 , wherein the discharge port comprises a magnetic washer and the connector of a discharge hose connected to the discharge port has a plurality of magnets that secures the discharge hose to the discharge port.
