plunger metering pump

Principles The reciprocating motion of the plunger help absorb and discharge working media(yellow). The plunger and seal all contact with the media, so proper choice of plunger material and seal method can ensure a ideal operatoin of the pump Pump head of plunger is easy, economic with metering accuracy. Seal method should be carefully chosen and maintained. The plunger and seal would be automatically on neutral in horizontal direction to keep friction at the minimum level. Plunger materials include stainless steel, oxidized ceramic which is anti-erosion, tough and durable. Major Performance Parameters Single-joint maxium flow 50000 liters/hour Maxium discharge pressure 50 MPa Steady state accuracy ±1% Media Viscosity0-800mm2/s Temperature of transporting media can reach over 450 degree centigrade Application It is suitable for the high pressure and large flow situation during the technique process of oil, pertolization and chemoindustry, or prying and loading system of dangerous chemicals injection and land gas transporting and marine oil and gas transporting, nuclear power and military industry as well as other key processes in environment protection, medication, paper making and food industry.
