As what we explained how is slurry pump impeller designed? Slurry pump is the key slurry pump parts influence slurry pump performance and working head by rotating to create hydraulic power in order to keep slurry pump efficiency.
Slurry impeller are divided into closed type of slurry pump impeller and open type of slurry pump impeller, Warman slurry pump, who is the most popular slurry pump manufacturer in the world, is showing how to select slurry pump impeller in following.
How To Select Slurry Pump Impeller? - Closed Impeller
Closed slurry pump impeller is more efficient than open slurry pump in general, and the efficiency is less affected by wearing life, because of the reduction of short circuiting leakage over the impeller vanes.
Comparing with open type of slurry pump impeller, the open type of slurry pump impeller if more prone to clogging when coarse particles are encountered, on the base of the same inch of closed type of slurry pump and open type of slurry pump.
Closed slurry pump impeller has a back wall and front wall around the vanes with the gap between the two walls for particle pass, therefore how to select slurry pump impeller, for closed type of slurry pump impeller, China slurry pump manufacturer Do Pump needs to make sure the particle pass ability for the slurry pump is larger than the solid that is pumping.
How To Select Slurry Pump Impeller? - Open Impeller
When China slurry pump Do Pump describes open impeller of slurry pump, it is actually explained as semi-open impeller by Warman pump company, which are designed for non-clogging particle design, more than that, the semi-open slurry pump impeller can overcome the limitation of particle pass ability that the closed slurry pump can not achieve, the open slurry pump impeller is also designed for high viscosity of the slurry and presence of entrained air in mineral processing, such as the floating system in iron mining.
Semi-open slurry impeller is designed with a single plate, it leaves the other side of impeller side exposed to the interior of the pump housing. The semi-open type of impeller can help the liquid immediately interacting with the rest of the liquid in slurry pump casing, however, the working efficiency of semi-open type of slurry pump is less than closed type of slurry pump, and the semi-open slurry pump is achieving less working head than closed impeller type of slurry pump.
How To Select Slurry Pump Impeller? - Conclusion
China slurry pump Do Pump introduced the type of slurry pump impeller, including closed type of slurry pump impeller, semi open type of slurry pump impeller and open type of slurry pump impeller.
Closed type of slurry pump impeller is achieving high working efficiency comparing with semi open type of slurry pump impeller as well as the working pressure, however, closed type of slurry pump is lack of particle pass ability while semi open type slurry pump is designed of non clogging characters.
