Pump Slurry Ebara

SAL SLURRY PUMPS FEATURES

No power overload: Specially designed impeller with a limit load feature is used so that there is never a power overload no matter what the head. Low energy consumption and yet highly efficient: Unique hydraulic design makes this pump more efficient than any other type. The initial rate of efficiency is sustained for reducing electrical power consumption. Highly durable: A special, wear-resistant iron casting is used for both body and impeller. Ample motor output allowance: The motor has ample power output allowance. It will operate without change of output with mixed solution of 1.1 specific gravity. Minimal gland packing leakage: Rear impeller vane ensures minimal leakage from durable gland packing. Corrosion and wear-resistant materials: Both chrome iron casting and two-phase stainless steel are available. Interchangeability makes a wide range of applications possible.

ABOUT WEAR AND CORROSION RESISTANCE

The impellers, which are subject to the greatest possibility of wear, are of tough high chrome cast iron about 20 times as wear resistant as ordinary cast iron. The casing, which is subject to less possibility of wear, is of less expensive low chrome cast iron with three to five times the wear resistance of ordinary cast iron.

TWO-PHASE STAINLESS STEEL

18-8 system stainless steel now widely favored as an anticorrosive material is vulnerable to an atmosphere with chlorine ions. To cope with this, EBARA has developed two-phase stainless steel which is resistant to stress corrosion cracks, for use especially in chemical plants, ocean development equipment and food industrial plants. Two-phase stainless steel is composed of austenite with a 40 to 60% ferrite content. The principle features of the superior corrosion resistance of austenite and the hardness and strength of ferrite-have been skillfully combined. This two-phase stainless steel can be used without the problems of conventional steel such as wear, corrosion, and cracking and is especially suited for use with sea water.
