Slurry Pump Volute Liners | Warman Pump Volute Liners

1. Functions: 

The primary function of the volute liner is to direct the flow of the slurry from the pump’s impeller to the discharge point. The volute liner is a curved funnel that gradually expands towards the discharge port. As the cross-sectional area increases, the volute slows down the slurry speed and elevates its pressure. It helps convert the kinetic energy generated by the impeller into pressure energy, the slurry is discharged at a heightened pressure through the outlet of the volute liner.

• Closed the slurry pump impeller to a certain space, so that inhaled and forced out liquid through the role of the impeller.
• Most of Pump volute are made to be Volute-shaped, it is also called the slurry pump casing. Because the area of channel section is widening , the high speed liquid around the slurry pump impeller gradually reduce the flow velocity, and part of the kinetic energy is converted to static pressure can effectively

• The slurry pump volute liner is not only collected liquid that thrown out by the slurry pump impeller, but also an energy conversion device
• Lead evenly the liquid to the impeller, collect the high-speed flowed liquid from the pump impeller, and send to the next level or export-led.
• Realize the energy conversion, Reduce the flow speed, transform the kinetic energy to pressure energy .
• Connect other components, and play a supporting role.

2. Material:

 Volute liners are typically made from materials to withstand the abrasive or corrosive nature of slurries. Common materials include high chrome alloy, rubber, or a combination of both. The polyurethane and ceramic materials are also available according to the needs of clients or unique working conditions.

3. Wear and Corrosion Resistance:

 Since slurries often contain solid particles that can cause wear and tear, sometimes they can be corrosive. so that the volute liner must be designed to resist abrasion, erosion, and corrosion. This ensures a longer lifespan for the pump and reduces maintenance requirements.

4. Easy to Maintain: 

This feature allows for easier maintenance and replacement of worn parts without requiring extensive disassembly of the pump, and minimal downtime.

5.Design Considerations: 

The design of the volute liner is critical for optimal pump performance. It must be carefully engineered to balance factors such as efficiency, wear resistance, and ease of maintenance.

6. Rubber vs. Metal Liners:

 The choice between rubber and metal volute liners depends on the specific application and the nature of the slurry being pumped. Rubber liners are often preferred for their superior abrasion and high corrosion resistance in slurry conditions containing fine particles without sharp corners, while high-chrome metal liners may be chosen for their durability in handling larger and coarser particles.
