摘要: A pump that includes a cylinder housing having a through bore. A cylinder liner is disposed substantially within the through bore and includes a substantially uniform aperture having a first diameter. A plunger includes an engagement portion having a second diameter smaller than the first diameter. The first diameter and the second diameter are sized to define a first diametrical clearance that is less than about 0.1 percent of the second diameter.
