Find out Pump Head without curve

You are handling lot many centrifugal pumps & is always struggling for design data which may or may not be available specially in case of vintage units its very difficult to recollect them.

Even in newer plants if you do not have all procedures in place for documents handling you might face the same problem. What to do in such a case?

Vacuum Pumps - Dry Vs Liquid Ring

Vacuum is any system of reduced
pressure, relative to local (typically atmospheric) pressure. Achieved with a pump, vacuum systems are commonly used to

• Remove excess air and its constituents.
• Remove excess reactants or unwanted byproducts.
• Reduce the boiling point.
• Dry solute material.
• Create a pressure differential for initiating transport of material

Liquid-ring and dry pumps offer the most advantages for the chemical process industries (CPI). Both of these pump types have bearings sealed off from the pumping chamber and do not require any internal lubrication because the rotors do not contact the housing. Both, when employing a coolant system, prevent the coolant from contacting the process fluid and causing contamination, and both use mechanical shaft
seals for containment.

Type of Valves - Globe

In the last article I discussed brief & important things about Gate Valve. Today I will discuss some basics of Globe Valve.

The Globe valves as name suggests is having a globe type spherical body which is divided in two parts by a baffle. Flow direction is steeply changed in this type of valve so the controlling of flow is better by the movement of restriction element.
