Abstract

A support system for a pump having a plurality of pumping elements is disclosed. The support system may include a first flange, a second flange opposite the first flange, and a support member between and abutting the first and second flanges. The support system may further include a plurality of fasteners, each being coaxially aligned with a respective one of the plurality of pumping elements, wherein each of the plurality of fasteners is configured to draw the actuating and pressurizing ends against the support member.

First claim

What is claimed is:

1 . A support system for a pump having a plurality of pumping elements, the support system comprising:
a first flange; a second flange opposite the first flange; a support member between and abutting the first and second flanges; and a plurality of fasteners, each being coaxially aligned with a respective one of the plurality of pumping elements, wherein each of the plurality of fasteners is configured to draw the first and second flanges against the support member.

2 . The support system of claim 1 , wherein each of the plurality of fasteners is spaced radially outward from the support member.

3 . The support system of claim 1 , wherein each of the plurality of fasteners includes a guide bore extending through a respective center of each fastener.

4 . The support system of claim 3 , wherein each of the plurality of fasteners is connected in tension to the first flange via a first nut, and to the second flange via a second nut.

5 . The support system of claim 4 , wherein the first and second nuts each include a guide bore passing through a respective center of each of the first and second nuts.

6 . The support system of claim 5 , wherein the pump includes a plurality of actuators configured to reciprocate between the first and second flanges, and the first and second nuts are each configured to be in a sealed relationship with one of the plurality of actuators.

7 . The support system of claim 1 , wherein the support member is a solid rod.

8 . The support system of claim 1 , wherein the support member is a tubular member having a solid wall and a hollow core.

9 . The support system of claim 8 , wherein the support member is coaxially aligned with one of the plurality of pumping elements.

10 . The support system of claim 1 , wherein the first flange includes a first socket configured to receive a first end of the support member, and the second flange includes a second socket configured to receive a second end of the support member.

11 . A pump, comprising:
an actuating end having a driving mechanism; a pressurizing end opposite the actuating end and including a plurality of pumping elements; a plurality of actuators, each configured to be reciprocally driven between the driving mechanism and a respective one of the plurality of pumping elements; a support member between and abutting the actuating and pressurizing ends; and a plurality of fasteners, each being configured to draw the actuating and pressurizing ends against the support member, wherein each of the plurality of actuators is slidably disposed within a respective one of the plurality of fasteners.

12 . The pump of claim 11 , wherein each of the plurality of fasteners includes a guide bore extending through a respective center of each fastener.

13 . The pump of claim 12 , wherein each of the plurality of fasteners is connected in tension to the actuating end via a first nut, and to the pressurizing end via a second nut.

14 . The pump of claim 13 , wherein each of the first and second nuts includes a guide bore passing through a respective center of each of the first and second nuts.

15 . The pump of claim 14 , wherein the guide bore of each of the first and second nuts is in a sealed relationship with one of the plurality of actuators.

16 . The pump of claim 11 , wherein each of the plurality of pumping elements is spaced radially outward from the support member.

17 . The pump of claim 11 , wherein the support member is one of a solid rod and a tubular member, wherein the tubular member has a solid wall and a hollow core.

18 . The pump of claim 17 , wherein the support member is a tubular member, and the pump further includes:
an additional pumping element coaxially aligned with the support member; and an additional actuator slidably disposed within the support member.

19 . The pump of claim 11 , wherein the actuating end includes a first socket configured to receive a first end of the support member, and the pressurizing end includes a second socket configured to receive a second end of the support member.

20 . A pump, comprising:
an actuating end having a driving mechanism; a pressurizing end opposite the actuating end and including a plurality of pumping elements, each being spaced radially outward from and symmetrically arranged about an axial center of the pump; a plurality of actuators, each configured to be reciprocally driven between the driving mechanism and a respective one of the plurality of pumping elements; a first flange connected to the actuating end; a second flange connected to the pressurizing end; a support member between and abutting the first and second flanges; and a plurality of fasteners, wherein:
each of the plurality of fasteners is connected to the first and second flanges and configured to draw the actuating and pressurizing ends against the support member;
each of the plurality of fasteners includes a guide bore passing through a respective center of each fastener; and
each of the plurality of actuators is slidably disposed within the guide bore of a respective one of the plurality of fasteners.
