Abstract

A pump system e.g. as a piston pump for hydraulic Jacquard nozzle looms has its moving parts e.g. piston and cylinder or drive shaft and positioning device of piston pump or rotary pimp respectively constructed from ceramic material e.g. sintered aluminium oxide of a hardness (RC) 78. The piston and internal bore of the cylinder of the piston pump are smooth for at least the travel of the piston, as is the internal box wall of the rotary pump drive shaft. Both the piston pump system and the drive shaft of the rotary system are built around a metallic core former which is then coated in the ceramic material.
