Abstract

A transfer pump includes a drive module having electronic components and a fluid module not including electronic components. The drive module provides motive power to a pump of the fluid module to power pumping by the fluid module. The transfer pump further includes a spout extending mounted to an outlet connector of the fluid module by an inlet end of the spout interfacing with an outlet end of the outlet connector. The spout is repositionable relative to the outlet connector while mounted to the outlet connector.

First claim

The invention claimed is:

1. A transfer pump configured to pump material from a bucket having an opening into the bucket, the transfer pump comprising:
a fluid module comprising:
a mounting frame;
a cylinder extending from the mounting frame in a first axial direction along a pump axis;
a piston extending into the cylinder, the piston configured to reciprocate along the pump axis to pump material from the bucket; and
an outlet connector supported by the mounting frame and having an inlet end and an outlet end;

a drive module supported by the fluid module, the drive module including an electric motor operatively connected to the piston to power reciprocation of the piston; and
a spout extending between a first end having a spout inlet and a second end having a spout outlet, wherein the spout is mounted to the outlet connector by the first end interfacing with the outlet end of the outlet connector, and wherein the spout is repositionable relative to the outlet connector with the first end interfacing with the outlet end, wherein the spout inlet and the spout outlet are spaced from the cylinder in a second axial direction opposite the first axial direction such that both of the spout inlet and the spout outlet are above the cylinder.

2. The transfer pump of claim 1 , wherein the spout inlet is located vertically below the drive module.

3. The transfer pump claim 1 , wherein the spout outlet is located vertically above the drive module.

4. The transfer pump of claim 1 , wherein the outlet connector outputs the material horizontally, and the spout redirects such horizontal flow of material vertically and then horizontally.

5. The transfer pump of claim 1 , wherein the spout is repositionable such that the spout outlet is below the drive module in a first position and is above the drive module in a second position.

6. The transfer pump of claim 1 , wherein the spout is rotatable relative to the outlet connector such that the spout outlet is disposed vertically over the bucket with the spout in a first orientation and such that the spout outlet is not disposed over the bucket with the spout in a second orientation.

7. The transfer pump of claim 1 , wherein the outlet connector includes a curved flowpath between the inlet end and the outlet end such that a flow through the outlet connector is redirected from substantially horizontal flow at the inlet end to substantially vertical flow at the outlet end.

8. The transfer pump of claim 7 , wherein the spout includes a first portion extending from the spout inlet and along a vertical spout axis, wherein the spout includes a second portion extending from the first portion to the spout outlet, and wherein the second portion extends radially relative to the vertical spout axis.

9. The transfer pump of claim 1 , wherein the spout further comprises:
a flange projecting from the first end, the flange including a notch formed in an outer edge of the flange.

10. The transfer pump of claim 9 , wherein the outlet connector further comprises:
a pin projecting from the outlet end, wherein the pin includes a pin body extending between the outlet end and a pin head;
wherein the pin is sized such that with the spout mounted to the outlet connector the spout can be moved vertically away from the outlet end with the pin head aligned with the notch, and such that the pin prevents the spout from being moved vertically away from the outlet end with the notch misaligned with the pin head.

11. The transfer pump of claim 10 , wherein the outlet connector further comprises:
a spout lock configured to interface with the spout to prevent rotation of the spout relative to the outlet connector.

12. The transfer pump of claim 1 , wherein the spout further comprises:
a duckbill nozzle connected to the second end of the spout by a clip;
wherein the second end includes an annular groove and the duckbill nozzle includes at least one slot; and
wherein the clip extends through the at least one slot and into the annular groove to secure the duckbill nozzle to the second end.

13. The transfer pump of claim 1 , wherein the drive module extends in the second axial direction from the mounting frame.

14. The transfer pump of claim 13 , wherein the spout outlet is spaced in the second axial direction from the mounting frame such that the electric motor is disposed axially between the spout outlet and the mounting frame.

15. The transfer pump of claim 14 , wherein a battery of the drive module is disposed axially between the spout outlet and the mounting frame.

16. The transfer pump of claim 13 , wherein the spout outlet is spaced in the second axial direction from the mounting frame such that an entirety of the drive module is spaced in the first axial direction from the spout outlet.

17. The transfer pump of claim 1 , wherein the spout is toollessly mountable to the outlet connector and toollessly dismountable from the outlet connector.

18. A transfer pump configured to pump material from a bucket having an opening into the bucket, the transfer pump comprising:
a fluid module comprising:
a mounting frame;
a cylinder extending from the mounting frame in a first axial direction along a pump axis;
a piston extending into the cylinder, the piston configured to reciprocate along the pump axis to pump material from the bucket; and
an outlet connector supported by the mounting frame and having an inlet end and an outlet end;

a drive module supported by the fluid module, the drive module including an electric motor operatively connected to the piston to power reciprocation of the piston; and
a spout extending between a first end having a spout inlet and a second end having a spout outlet, wherein the spout is mounted to the outlet connector by the first end interfacing with the outlet end of the outlet connector, and wherein the spout is repositionable relative to the outlet connector with the first end interfacing with the outlet end;
the spout including a flange projecting from the first end, the flange including a notch formed in an outer edge of the flange;
wherein the outlet connector includes a pin projecting from the outlet end;
wherein the pin includes a pin body extending between the outlet end and a pin head;
wherein the pin is sized such that with the spout mounted to the outlet connector the spout can be moved vertically away from the outlet end with the pin head aligned with the notch, and such that the pin prevents the spout from being moved vertically away from the outlet end with the notch misaligned with the pin head.
