What is slurry?

Slurry is a semi-liquid mixture comprised of fine particles; examples being manure, cement and starch. Due to these added particles, and the fluid’s thicker consistency, it is crucial a special pump is selected.

How to select the Right Pump?

To ensure your pump is suitable, consider the following attributes:

• Impeller: the impeller should have large enough passageways so that the solid particles, no matter their size, can pass through without clogging.

• Casing: The casing of the pump, which handles the pressure, should have larger gaps between the impeller and the cut water tongue, to reduce wear and prevent large solid particles from getting stuck.

These two elements, when combined with the other components, have crucial roles in the operational success of the pump moving the slurry. If these parts are not appropriate you may be spending money on maintenance and causing longer downtime. 

Design advantages of each parts:

1. Well designed for interchangeable wet parts with metal lined slurry pump.

2. Casing - Casing halves of cast or ductile iron with external reinforcing ribs contain the wear liners and provide high operating pressure capabilities

3. Bearing assembly - A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.

4. Pump frame - A rigid, one-piece casting cradles the "cartridge" shaft and bearing assembly. A minimal number of through bolts hold the pump casing to the frame.  An easy means of external impeller adjustment is provided in a convenient position below the bearing housing.

5. Impeller - Front and rear shrouds have pump-out vanes. This design reduces recirculation and seal contamination, Elastomer impellers are made from rubber coated high tensile steel, Cast-in impeller threads require no impeller insert or nuts.

6. Liners - Rubber elastomer liners are interchangeable with hard metal. The elastomer liners are bolted, not bonded, to the outer casing.  Elastomer seal rings back all liner joints.

7. Shaft seal - Packing seal,Centrifugal seal, and Mechanical seal.
