The pump is high pressure driven by a cam lobe and is a mechanical pump, the pump seal is probably of a hard material or teflon which causes the cricket like sound. Unless you replace it with an electrical one. But replacement mechanical pumps will eventually make noise again. Dunno if an electric can be put in place of the mechanical and high pressure electric pumps are typically noisy.
