3/2D-HH High Pressure Slurry Pump Parts DH2147BFA05 Impeller

Tobee 3/2D-HH High Head Slurry Pump Impeller DH2147BFA05 is the back full closed type impeller, to a certain extent, the work life of the impeller can be improved.

Slurry Pump Wear Parts are directly connected with slurries, They are very crucial to the service life. The wetted parts include impeller, volute liner, throatbush, frame plate liner insert, cover plate liner, frame plate liner and casing etc., These parts are very easily worn-out components because they work under longtime impact of abrasive and corrosive slurries in site. For the long service life of pump parts, the material plays an important role here.

Selection of the type of materials to be used for slurry pumping applications is not a precise procedure. The procedure must first account for all the factors (variable characteristics) of the particular slurry. The procedure must take into account the constraints imposed by the following:

1. Type of slurry pump.
2. Slurry pump speed.
3. Options within the range of the models available.

Slurry Pump Impeller Type
Any type of impeller can be used in slurry applications, but closed slurry pump impellers are more common because they are high efficient and abrasion Resistance,. Open slurry pump impellers are usually used well for high concentration solids as they are less likely to clog. For example, the small fibers in paper stock which, in high densities, may have a tendency to clog the impeller. Pumping slurry can be difficult and you want to avoid a clogged pump at all costs.

Slurry Pump Impeller Size
The size of the slurry pump's impeller must be considered to ensure it holds up against abrasive wear. Slurry pump impellers are generally larger in size when compared to slurry pumps for less abrasive liquids. The more “meat” the impeller has, the better it will hold up to the task of pumping harsh slurry mixtures. Think of the slurry pump's impeller as a football team's offensive line. These players are usually large and slow. Throughout the whole game they are beaten up, over and over again, but expected to withstand the abuse. You wouldn't want small players in this position, just like you wouldn't want a small impeller on your slurry pumps.

Slurry Pump Speed
Your process speed doesn't have anything to do with choosing your slurry pump impeller, but it does have an effect on the life of your slurry pump impeller. It is important to find the sweet spot that allows the slurry pump to run as slow as possible, but fast enough to keep solids from settling and clogging. If you are pumping too fast, the slurry can quickly erode the impeller due to its abrasive nature. This is why it is important to select a larger impeller if possible.

When you're 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 you'll inflict on the impeller. However, the impeller isn't the only thing you have to worry in your 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.
