high quality open impeller slurry pump factory

We use CFD, CAD method for product design and process design based absorbing experience of world leading pump companies. We integrate molding, smelting, casting, heat treatment, machining and chemical analysis, and have professional engineering and technical personnel.

When dealing with slurry, you generally want to go bigger and slower. The thicker the impeller, the better it will hold up. The slower the pump, the less erosion will inflict on the impeller. However, the impeller isn’t the only thing to worry in slurry pump when dealing with slurry. Tough, durable materials of construction are necessary most of the time. Metal slurry pump liners and wear plates are common in slurry applications.

Mixers can also help agitators when pumping very dense particles. In applications where the tank is small and/or where pumping is desired to lower the water level in the tank, a slurry pump with an internal cooling system should be considered to avoid overheating of the stator (when the water level gets low). When pumping sediment from a dam or lagoon, consider the use of a raft unit, which is a submersible device. Agitators are recommended, as well as one or more mixers that can be mounted on the raft or pump to resuspend particles for successful pumping of particles.

It is often used if a short period of dry running is expected. Fluid is introduced into the area between the back of the seal face and the tight-fitting outlet on the drive side of the slurry pump.

Slurry pumps can also simply axially adjust the clearance between the impeller and the adjacent throat casing sealing surface. This helps to maintain pump performance when internal components begin to wear.
