Casting of centrifugal pump casing

The water pump body and flange accessories made of gray iron and ductile iron are generally mass-produced using green sand casting technology, which has the advantages of low casting cost and mature production process.

ZOOMZU in Jiangsu Province, China has equipped 13 water pump and centrifugal pump casting enterprises with automated casting molding lines, which are used for the automated casting production of pump bodies, flange covers and other castings of centrifugal pumps. The production cost of castings is low and the efficiency is fast. For pump body castings, a coated sand core needs to be placed in the casting molding process, and the mold is relatively complex. An automated casting molding machine with vertical sand spraying on the top and bottom of the mold is selected, and a molding sand box with a size of 650mm-750mm is used. The molding effect of the sand mold will be more uniform, and the casting yield will be high. Therefore, the use of a water splitting type automated casting molding machine for the casting production of pump bodies and pump accessories of centrifugal pumps is a very suitable choice;
