MD 4 NT 隔膜泵
MD 4 NT 隔膜泵
此类三级隔膜泵是针对非腐蚀性气体的持续的、无油抽气的优秀解决方案。它们具有卓越的JX真空，可达1mbar。所有与所抽气体或蒸汽接触的部件都由铝、不锈钢和经仔细选择的塑料等材质制成，可广泛用于非腐蚀性气体。全新的NT系列泵运行更加安静，振动更低，具有更好的气密性，整个系统的性能得到改善。高柔韧性的纤维增强的双层膜片采用氟橡胶（FKM）材质，延长了运行寿命。 此款三级隔膜泵是持续无污染抽气或者在特定真空需求下抽取非腐蚀性气体的J佳选择。它们非常适合于物理和分析领域的应用。好的JX真空使其在很多应用中可以很好地取代旋片泵，比如用于分子泵的前级泵，或用于粘稠介质的脱气。
