Safeseal JCS1 is a rugged, pump-integrated single seal designed for clean and lubricating fluids such as water, oils, solvents and low-consistency paper stocks. The JCS1 seal is easy to install from the impeller side. JCS1 is very advanced in its technical capabilities, including a patented drive mechanism for seal faces and self-aligning, elastically mounted thrust ring.

The JCS1 is originally designed for Sulzer AHLSTARUP pumps and later expanded to cover Andritz process pumps and other equipment.

Several variants of the design available for different services:

CS1F - Single application-specific seal with flush into the medium

JCS1A - Single application-specific seal for Sulzer liquid ring pumps and Andritz ACP pumps

JCS1M - Single application-specific seal for Sulzer multistage pumps

JCS1G - Single application-specific grease seal

JCS1FM - Single application-specific seal with flush into the medium for Sulzer multistage pumps
