In at least one aspect, this disclosure relates to a wellsite pump for a well site having a wellbore penetrating a subterranean formation. The well site has a conduit to pass a wellsite fluid about the wellsite. The wellsite pump includes a housing having an intake and an outtake, at least one hydraulic motor to pump the wellsite fluid from the intake and through the outtake, at least one driver coupled to the hydraulic motor and movable therewith, and a power source. The intake is in fluid communication with the conduit, and the outtake is positioned a distance upstream of the intake. The hydraulic motor includes a rotor and a stator. The power source drives the driver and the hydraulic motor coupled thereto whereby the wellsite fluid is advance from the conduit to a location upstream therefrom.
