Product description: The vacuum pump BS-ZK-26 is an important corollary equipment to raise filtering efficiency and enhancing degassing effects. To avoid filtering medium polluted, oil free diaphragm type vacuum pump is a common choice. Oil free diaphragm type vacuum pump forms a vacuum by back and forth movement of rubber diaphragm. Its vacuum pressure is around 0.08Mpa (single-stage). ZK-26 is specially designed to assort various demands of the laboratory vacuum equipments. It can be used for vacuum concentration, vacuum filtration, vacuum drying, etc. Product Features 1. Provide enough motor power to reduce fevers. 2. The vacuum membrane is made of high quality oil resistivity and fatigue resistance rubber with 3mm interlayer to strengthen the textile skeleton. Long service life. 3. Compact and practical, simple operation, high efficiency and low noise. 4. Optional regulating type and vent valve configuration.
