Iron Casting, Pump Castings Tags:

Description

The pump casing is a metal casting outer housing, pump volute or pump shell that holds a pump and protects the internal pump parts, allowing fluid to flow through while maintaining pressure and preventing leaks by sealing off the inside of the pump from the atmosphere.

The two main types of casings in centrifugal pumps are volute casings and diffuser casings. A very common classification of pump casings is the diffuser construction. A diffuser is actually a series of vanes surrounding the impeller which accepts the discharge of liquid from the impeller.

A cast iron impeller is typically made from gray iron as it is the most common cast iron due to its good castability, machinability, and vibration damping properties, although in situations requiring higher strength and impact resistance, ductile iron might be used instead.

Cast Iron pump housing’s material

Gray iron pump housing ASTM A48 Standard Specification for Gray Iron Castings, for example, ASTM A48 Class 30, ASTM A48M class 35, ASTM A48 class 40, etc. More brittle but has better vibration damping and is generally cheaper than ductile iron.
Ductile iron pump casing ASTM A536 Standard Specification for Ductile Iron Castings. ASTM A536 grade 65-45-12, ASTM A536 Grade 80-55-06, ASTM Gade 60-40-18, etc Offers greater strength and ductility, making it suitable for applications with higher impact loads.

 Investment Casting Sand Casting Centrifugal Casting Precision Machining

Process

 Investment casting, also named lost-wax casting, making parts from molten metal. Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex, metal parts that can be made of nearly any alloy Centrifugal casting, sometimes called rotocasting, is a metal casting process that uses centrifugal force to form cylindrical parts

Precision machining from the tubes, bars, blocks to get the required shapes.

Metal

 steel, brass, copper and bronze steel, brass, copper and copper, cast iron Brass, bronze and copper alloy steel, brass, copper and bronze, aluminum, etc
