Singleend, double balanced, independent direction of rotation, wave spring with spring protector. The still spring structure allows high speed operating conditions. The spring is separated from the sealed mediums so it will not be jammed. Simple structure, easy to install with stable performance. Widely used in paper pulp production, pharmacy, food processing, sewage treatment and chemical processing.

The JCS1C is a singleacting seal integrated into the target device. Developed for environmentally clean and lubricating liquids with low consistency (< 2%), such as water, various oils, solvents and pulp. The balanced design allows troublefree operation even in sudden pressure fluctuations, ensuring reliable and longlasting operation under demanding conditions.

The JCS2A is a doubleacting seal integrated into the target device. Developed for pumps used for environmentally hazardous and abrasive liquids when operating limits of singleacting seals are exceeded. The doublebalanced design allows both pressurized and nonpressurized sealant use, ensuring reliable operation under demanding conditions.
