Diaphragm Vacuum Pump
Products Introduction
Our Diaphragm Vacuum Pump has the features of continuous oil free pumping , low noise level , higher efficiency , long lifetime . It is mainly used in medicinal products analysis , industry of fine chemicals , biochemical pharmacy , food examination , The criminal investigation technology , etc . It is used with the precision chromatography instrument , the necessary of laboratory . This product is specially designed for laboratory , reliable and easy to use . These series of products have obtained the national patent .
FEATURES:
- The product could work without any medium and does not produce pollution .The gas exchange room is placed with filtering material , to ensure that the air is clean .
- New material and new technology are adopted in production . It is convenient to move , and work smoothly , thus ensuring the ideal vacuum degree and higher air velocity .
- Using frictionless membrane body movement , does not produce heat , no friction consumption . Imported rubber diaphragm has corrosion resistance and long service life .
- Automatic cooling exhaust system is designed in the body , ensures continuous operation 24 hours a day .
- The pressure adjustable design can satisfy a certain range of vacuum and gas velocity .
- Bearing imported classic bearing , smooth operation , low noise , high efficiency .
- The parts in contact with the gas of anticorrosive pump is with TEFLON surface treatment , which have complete ability of resistance to chemical corrosion .
- Special motor is ODM provided by the export of professional motor manufacturer and has got the European CE certification . It has the reasonable rotation design , equipped with a power overheat protector , when the pump body temperature reached 130 degrees , it will automatically power off , to protect the motor from being damaged in the long running work .
- Small volume and light weight , easy to move , save space , convenient repair and maintenance .
