Benefits

The single cartridge seal can be connected to all common API Plans, such as 01, 02, 11, 31, 32 + 51, 61 (62) and 23 + 51, 61 (62). The seals are available for all of KSB’s API pumps.

The throttling bush enables connection to a gas, steam or liquid quench, depending on the seal variant. This prevents outboard incrustations at the seal.

The API Plan combination 02 + 23 with high-efficiency pumping ring is perfectly matched to applications with hot fluids.
