里瓦隔膜式计量泵具有计量精度高、完全密封无泄漏等显著特点，适用于无菌领域中的应用。
LEWA diaphragm pump, apart from high accuracy, hermetic tightness is an outstanding feature for aseptic operation.
该型泵为单级、单吸、卧式、径向剖分，轴向吸入、径向排出。全密封，无泄漏。
This pump is of horizontal single stage and single suction type with radial split, axial suction and radial discharge. It is fully enclosed and leakage free.
安全密封：通过并入比泵流体压力更高的低密度阻隔液，保证了没有泄漏发生。
Safety seal: through the incorporation of a low specific gravity barrier fluid at a higher pressure than the pumped fluid, it guarantees a no leakage sealing action.
