Type SG(SGH) sand gravel pumps are a single casing pump connected to the cassette shell structure, with wide wet passage.This sand pump wet parts are made of Ni hard and high chrome abrasion resistance alloys material.The discharge direction of pump can be oriented in any direction of 360 degree. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and resistance. The gravel pumps are designed for continuously handling the most difficult high abrasive slurries which contain too big solids to be pumped by a common pump.
