Corrosion resistant vacuum pumps

The application in the chemical industry of the water ring pump in recent years makes us accumulate a wealth of experience in special material application which includes application of stainless steel contacting the liquid, plating special components with nickel, macromolecule spray coating and successful application of the pure titanium material. When the cycle medium contains strong acid and strong alkali, and is inflammable ,explosive, poisonous and harmful, our products can be sure to work more smoothly, run more reliably and have longer life.

Corrosion proof vacuum pump—High polymer spraying, electroplating, chemical palting
P coating is a new and patent spraying technology of our company .P owns some specific characteristics like: hard and crisp, high crystallinity , flame resistance , perfect thermal stability , high mechanical strength , favorable electric property , high chemical corrosion resistance ,etc. At present , PPS is regarded as one of the best engineering plastics in heat resistance. Its heat decomposition temperature is  over 260℃.And its chemical resistance ranks second only behind PTFE (Polytetrafluoroethylene).Besides, it has some excellent features like: low molding shrinkage, low water absorption, fire resistance, good vibration fatigue resistance, strong arc resistance ,etc .Even more in the condition of high temperature and high humidity m it shows magnificent electrical insulation property. All the part in the vacuum pumps can be processed by spraying, such as shaft, pump cover, impeller, port plate etc.

Corrosion proof vacuum pump—titanium pump

Titanium pump is one of the corrosion proof water ring pump, which means the components contacting with the liquid is made by titanium or titanium alloy. Its seal is double end surface mechanical seal. The pump is used to transport various organic or inorganic corrosive liquid, especially saline solution containing chlorine. The pump cannot transport fuming nitric acid, hydrofluoric acid, chlorhydric acid with density ＞30%， more safe and reliable than the vacuum pump with normal material. The price of titanium and titanium alloy is relatively high, so it is applied under the condition that other material corrosion proof pump cannot be qualified. Titanium or titanium alloy vacuum pump is generally made by found and welding. The specification and size of the pump and the matching package unit can be produced to non standard according to the customers’ requirement.
