Introduction: Construction of this gravel pump lmg is of single casing and wide wet passage. The wet parts are made of high-chrome wear resistant alloys. The discharge direction can be oriented in any direction of 360¡ã due to its connection by means of clamp bands. This type of pump owns the advantage is of easy installation, good performance of npsh and wear-resistance. Gravel pumps are designed for continuously handling the most difficult higher abrasive slurries, which contain too big solids to be pumped by common pumps. Application: They are suitable to transport slurries in the mining, metallurgy, coal washery, dredging and other fields.
