Dynamic Seals Engineering

Ghaziabad, Uttar Pradesh

Advantages

• Ideal seal for standardizations
• Universal applicable for packings conversions, retrofits or original equipment
• No dimensional modification of the seal chamber (centrifugal pumps) necessary, small radial installation height
• No damage of the shaft by dynamically loaded O-Ring
• Extended service life
• Straightforward and easy installation due to pre-assembled unit
• Individual adaptation to pump design possible
• Customer specific versions available
