Vermicular cast iron with strong tensility, flexuaral strength and abrasion resistance. Products adopted the processing center processing, ensure each component concentricity, round and smooth, without the "O" ring, assembly is simple, strong reliability. Products support, mail, air inlet nozzle, couplings and other major aluminum casting with vacuum die casting, bright and clean appearance, no leakage, no oil leakage.
EXCELLENT PERFORMANCE
Intergrated cylinder structure and high precision design to ensure the pump is able to work reliably in various conditions.
Constant oil supply pressure system is utilised to maintain the lubrication quality of the oil as well as the reliability of the internal seals. Both measures have been taken to further enhance the reliability and the durability of the vacuum pump.
Automatic anti-backflow valve design, to protect the vacuum pump system from the contamination of the oil and the oil vapor after the pump has been stopped.
Double gas ballast, meet the different requirements of steam exhaustion.
Imported oil seal and fluororubber seals can match different tough working conditions.
