High-Pressure Gear Pumps KP 0

High-Pressure Gear Pumps KP 0 High Pressure Gear Pumps KP 0 Construction According to its design, the Kracht KP 0 external gear pump belongs to the type of so-called gland type pumps. The essential functional elements, gearing and bearing glands are located in an aluminium housing of high-strength extruded alloy, which is limited laterally by the the cover plate and flange cover. The gearing, made of case hardened steel with surface hardening, consists of the drive shaft wheel and pin wheel. The highest manufacturing quality is guaranteed by shaving the tooth flanks. The shaft journals are finely...
