The present invention concerns a tooling system for maintaining hand pumps (1) for deep boreholes remarkable in that it consists of a winch (4) comprising means for attachment to the body (2) of the pump (1) and intended to be attached facing an inspection hatch (3) formed on said body (2) of the pump (1), a pulling rope (5) controlled by said winch (4) and carrying, at the end of same, a friction and stop gripping device (6), and a return wire (7) linked to said gripping device (6) and able to release the engagement of the gripping device (6). According to a first variation, the gripping device (6) is a weighted sliding knot. According to another variation, the gripping device (6) is a C-plate (60). The tooling system according to the invention allows pumps to be used in compliance with VLOM requirements.
