SIKOPUMP - Following are the salient features of Piston Metering Pumps: High pressure: Piston type metering pump has the highest pressures among all the metering pumps, it can reach 50MPa pressure. So it can be high pressure metering pump as well. Self-priming: It has simple structure, so easy maintenance need. Because of its special structure, it has a very strong self priming ability; it can be installed above the liquid level. Washing seal: Plunger metering pump has a seal, so it is not suitable for the dangerous chemical liquid delivery. With washing seal, a long service time can be achieved. Heating jacket: The piston metering pump head can be insulated a heating or cooling jacket, so this pump is very suitable for the high temperature liquid delivery. Heating model can be hot water and so on
