1. A pump for introducing treatment fluid into a well, comprising:
a power end having a piston disposed in a power end bore;
a fluid end having a fluid end bore and a chamber in fluid communication with a suction valve and a discharge valve; and
an expandable bellows disposed in the chamber and in fluid communication with the fluid end bore;
wherein the power end is configured to reciprocally expand and contract the bellows within the chamber based on movement of fluid by the piston,
wherein the power end bore and the fluid end bore are fluidly coupled to form a continuous pump bore without external piping therebetween, and
wherein:
the power end further comprises a power end housing, with the power end bore disposed in the power end housing,
the fluid end further comprises a fluid end housing, with the fluid end bore disposed in the fluid end housing,
the power end housing and the fluid end housing are configured to be directly coupled together, and
the continuous pump bore is entirely disposed within the power end housing and the fluid end housing.
