Abstract

A rotary pump includes a rotatable shaft, a rotary drive member connected with the shaft and having an angled drive surface centered about a shaft drive axis. One or more pumping units each include a piston linearly displaceable along a pump axis, spaced from and extending parallel with the drive axis, a and having a working end for pressurizing a fluid and an opposing driven end. A coupler assembly is configured to operably couple the piston driven end with the angled drive surface such that rotation of the rotary member linearly displaces the piston along the pump axis and configured to substantially reduce sliding contact between the piston and any portion of the rotating pump component. Each piston is disposed within a bore through a drive base and a removably connected pressurizing base and is formed of drive and pressurizing portions, the pressurizing portion being separately removable from the pump.
