Casings are newly designed one piece style, including extra deep ring section for greater rigidity under vacuum of pressure service. In many of the longer cases inspection ports are provided to give access for internal and clearance check.Impellers and Shaft are made of SG iron and separate forged shaft duly precision machined is shrink fitted accurately machined for close tolerance operation S . G Iron Forged steel material is used for better strength and longer life.Steel shafts are made from alloy steel [BS : 970 series of steel] toughened to resist bending and for imparting high fatigue life. The shrink fit through the impeller eliminates torsional deflection and permits increased pressure ratings and greater efficiencies.
