NBR FKM Diaphragm Seals O-rings for Diaphragm Drum Pumps Solids Diaphragm Pumps
Introduction:
Diaphragm pump is divided into pneumatic diaphragm pump and electric diaphragm pump, pneumatic diaphragm pump as the name implies is the kind of using compressed air as the power, to form a diaphragm reciprocating deformation volume change of positive displacement pump. Its operating principle and electric diaphragm pump is similar to the plunger pump, because the characteristics of the working principle of the diaphragm pump, in the process of diaphragm pump use, the diaphragm becomes an important accessory, but also because the positive displacement is particularly important.
Characteristics:
• Good elasticity, anti aging, strong sealing.
• High and low temperature resistance, wear resistance, oil resistance, acid and alkali resistance, corrosion resistance.
Specifications:
| Note: The hardness of the O-ring material is the most important indicator for evaluating the sealing performance. The hardness of the O-ring determines the compression amount of the O-ring and the maximum allowable extrusion gap of the groove. Since the nitrile seal of Shore A70 can meet most of the service conditions, if there is no special instruction for the sealing material, generally provide nitrile rubber of Shore A70. | |||||
