1. The material must be able to bear slurry abrasion, erosion and corrosion.
2. In order to get a longer service life, under the same parameters paremeters, the working speed of horizontal slurry pump will be slower than clean water pump.
3. The bearing and roller of horizontal slurry pump can adapt to overloading, bad working conditions and so on.
4. Allowed to pass abrasion of solid particals, in particular cases, the size of solid particals is big, the biggest horizontal slurry pump can allow to pass solid particals under the size of 530 mm.
5. In order to satisfy different slurry and the needs of the different installation conditions, it must have various forms of shaft sealing and material.
