Everest – Hybrid Variable Pitch Dry Screw Vacuum Pump

Q : What do you mean by HYBRID SCREW DESIGN? In what way it is diferent from the variable pitch screw manufactured by other Screw Pump Manufacturers?

Ans: Hybrid Screw design ofer advantages both single pitch and variable pitch. Hybrid screw was designed with two constant pitches and one variable pitch.

General information of Coating

Electroless plating is the process of using an auto-catalytic chemical reaction to deposit a coating onto a wide range of substrates. Electroless nickel plating actually uses a solution that is a nickel phosphorous alloy and the plating solution composition can be tailored to suit a particular application.

How To Get Most Out Of Your Coated Dry Screw Vacuum Pump

Coating is generally highly resistant to corrosive vapours and gasses. since the pump is running under vacuum most of the end product entering the pump is in vapour form at inlet. Since there is compression happening inside the pump in some cases this vapour may get converted to liquid/ co densate. This if not flushed throughly from inside the pump at pump shutdown will crystilize/solidify inside the pump.

Efficient Vacuum Distillation 

at reduced pressures is a widely used process in the chemical industry, specially used in extraction / purification of essential oils, deodorisation of Vanaspati / Vegetable Oils and purification & drying of chemicals. The advantages of low-pressure distillation process over Atmospheric pressure distillation are as under:

Waste Lubricating Oil Purification and Recovery

It may be surprising to note that, under normal circumstances, lubricating oil cannot be easily destroyed; it only gets dirty and is easily contaminated by other solvents. This property makes it a potential pollutant that must not be allowed to get into the environment. The only option is to collect it and treat it so that its original properties are restored and thus enable its re-use. Modern lube oil has at least 8 additions blended into it so as to enhance its life and working properties.
