Industrial ceramic plunger is an excellent choice for use in displacement pumps that transport chemical or abrasive media, as they can withstand high pressure levels while boasting exceptional hardness.Plunger pumps work similarly to piston pumps by employing a reciprocating plunger that creates both negative and positive pressure to force liquid out through outlet valves. Different materials are used for building the pump cylinder and its seals; this choice will greatly influence durability of each plunger pump.
