Product Description

Polyurethane Lined Slurry Pumps for Electric Factory Coal Preparation
 

The Slurry Pump Polyurethane Impeller design is crucial as it influences flow patterns and ultimately, wear rates throughout the pump. The number of impeller vanes usually varies between three and six depending on the size of the particles in the slurry.

Most slurry pump casings are [slower" than their water pump cousins, primarily to reduce wear though lower internal velocities. Slurry Pump Parts including many types. Such as Slurry Pump Polyurethane Throatbush and Slurry Pump Polyurethane Back Liner, which replaceable with standard metal and rubber liners.


Polyurethane material for Slurry Pump Liners
i)  Used for pump side liners, where the peripheral speed of the impeller is higher than 27.5 m/s, (and precluding the use of standard rubber) and used for impellers where occasional trash may damage a rubber impeller.
ii)  Erosion resistance is greater where erosion is of a sliding bed type rather than one of directional impact.
iii)  Has less erosion resistance to fine solids than natural rubber. Has greater erosion resistance to coarse sharp edged particles than natural rubber, in some circumstances.
iv)  Unsuitable for temperatures exceeding 70°C and for concentrated acids and alkalies, ketone, esters, chlorinated and nitro hydrocarbons.
