1. A system for pumping treatment fluid into a well, comprising:
a bellows pump configured to pump treatment fluid into the well, comprising:
a power end comprising a piston;
a fluid end having a chamber; and
an expandable bellows, wherein the power end is configured to reciprocally expand and contract the bellows within the chamber based on movement of fluid by the piston;
a make-up system configured to maintain a controlled volume of fluid between the piston and the bellows; and
a control system having one or more sensor configured to detect one or more parameters of the system;
wherein:
the make-up system comprises a make-up fluid source fluidly coupled to the bellows and to at least one additional component of the system;
the make-up system is configured to receive heat via circulation of fluid with the at least one additional component of the system, and to discharge heat via circulation of the fluid with the bellows, wherein the at least one additional component comprises another pump;
the control system is configured to receive data from the one or more sensor, to evaluate the sensor data to detect a leak, and responsive to detecting a leak, to fluidly isolate the make-up system from the bellows; and
the control system is further configured to evaluate the sensor data to determine whether the bellows and piston are out of sync, and responsive to determining that the bellows and piston are out of sync, to use the make-up system to adjust the amount of fluid between the piston and the bellows to return the piston and bellows to sync.
