PP PVC CPVC PVDF Plastic Pall Ring for mass transfer

PP PVC CPVC PVDF Plastic Pall Ring for mass transfer

Short Description:

Plastic Pall Ring packing is an economical and versatile industry standard with well-known performance characteristics. Plastic Pall ring has an advance on the Raschig Ring, the Pall Ring has similar cylindrical dimensions but has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.

Product Description

• Good capacity and low pressure drop
• Higher liquid hold-up and residence time
• Versatile standard packing
•  High mechanical strength


1. Good Capacity and Low Pressure Drop
• Higher capacity and lower pressure drop than ceramic packing.
• Multiple sizes provide ability to optimize capacity and efficiency based on application requirements.
2. Higher Liquid Hold-up and Residence Time
• Relatively high liquid hold-up allows good absorption efficiency with slow chemical reaction.
3. Versatile Standard Packing
• Lower sensitivity to liquid and vapor distribution quality allows use with conventional liquid distributors.
4. High Mechanical Strength
• Ring and spoke construction provides high mechanical strength, which allows use in deep beds. 


• Absorption, scrubbing, and stripping services
• Versatile alternative to metal Pall rings

Material Available

Polypropylene, Glass Filled Polypropylene, Low Density Polyethylene, High Density Polyethylene, PVC, CPVC, Kynar (PVDF), Halar (E-CTFE), Tefzel (ETFE), Glass Filled ETFE, PFA.
