The type JCS2 seals are designed to be used in pumps for environmentally hazardous and
abrasive liquids when operating limits for single-acting seals are exceeded.
The double-balanced design of the seal allows the use of both pressurized and non-
pressurized sealant fluid. This design ensures reliable and long-lasting operation under
the most demanding conditions, reducing seal fluid consumption, and prevents environmental
emissions.
Several variant of the design available for different services:
JCS2P — OEM (Sulzer Ahlstar Up) Engineered double external stationary spring O-ring
mounted seal
