Multi sprung seals are designed such that an even face load is applied over the face area but a number of compression springs.
This results in higher pressure sealing capabilities. They are commonly used in petrochemical or chemical applications. The ranges include the AESSEAL M01U to M06U Range as well as a number of upgrade alternatives such as the M0FC range which is compatible with Fristam Pumps in replacement with the T01FU Range.
