Abstract: A metering pump is provided with stroke adjustment and having a laterally, stress-free, self-aligning piston with a floating seal. A wire coupling is utilized between the pump piston and a plunger reciprocated by a drive motor. The wire is so mounted as to be pre-loaded in tension but may bend. The piston is positively driven in the axial direction but floats free laterally with no lateral force applied and with no linear backlash. Thus, the piston is positively driven, absolutely rigid in the axial direction. The arrangement is suitable for a relatively delicate and brittle piston acted upon by relatively large liquid pressure and driving force.
