Abstract
A shaft alignment system for pumps which utilizes a clamp for holding a reciprocating shaft to a piston in an abutting relationship. The clamp can be loosened and retightened after the piston, which is attached to the reciprocating shaft, is inserted in a cylinder. Forces induced on the piston after insertion in the cylinder cause the piston and shaft to be realigned. Resecuring the reciprocating shaft assembly to the piston assembly causes the system to be precisely aligned in a transverse direction.
