Temperature Resistance up to 150 °C (302 °F)
Dynamic Working Pressure up to 10BAR (145 PSI)
High Number of Cycles > 300,000

Also including:

DESIGN

• Very good flow CV’s
• Easy cleaning
• Suitable for the use with large particulates (fruits, nuts)
• Dome free housing design
• Leak detection

RESISTANCE

• Extremely good chemical resistance
• Temperature stable material
• High temperature resistance

MATERIAL

• Homogeneous material
• No elastomer
• Plastic like PTFE (polytetrafluoroethylene)
• No cold flow
• Elasticity, elastic recovery
• Low adhesive coefficient

DURABILITY

• Good mechanical material properties
• Good dynamic and static pressure stability
• High number of switching cycles and load cycles

Technical Benefits of the
P3 Diaphragm

AREA: P³ DIAPHRAGM ADVANTAGES

Flow Characteristics: Compared to bellows flow from the side is possible.

Cleaning Abilities: Excellent cleaning due to the membrane and body design.

Pressure Shock Resistance: Less sensitive to dynamic pressure shocks as the diaphragm is supported from behind. The unsupported space behind the diaphragm is minimized.

Service Life: High number of cycles provides a long service life.

Maintenance: Due to the design, Südmo valves are quick and easy to repair and maintain.

Security: Safe and secure leakage detection.

General Technical Data

Commercial Benefits of the
P³ Diaphragm

AREA: P³ DIAPHRAGM ADVANTAGES

Operation and Environment: Improved equipment efficiencies, better protection of downstream equipment, and minimized batch contamination due to the more reliable diaphragm. Shorter and easier cleaning cycles reduce the overall demand for media (water, caustic / acid concentrates).

Maintenance Costs: A longer diaphragm service life increases process run time and reduces labor and documentation costs for membrane replacement.

Spare Parts: Only the P3 diaphragm is replaced, which reduces spare parts and inventory carrying costs.

Cost Savings: Based on the service life over several years you will see significant cost savings, improved product conditions, and longer process run times.
