摘要： A centering support for a piston in a piston-type pump having a diaphragm extending between the piston and the cylinder to define a product end of the pump and a driven end of the pump includes at least three equally radially spaced, centering elements extending radially outwardly from the piston for contacting the cylinder wall. The centering elements define a gap between the piston and the cylinder wall. The centering elements are disposed on the piston spaced from the diaphragm at the product end of the pump.
