The Sepco® RBA is a multiple, cartridge mounted seal. The flexible parts are mounted in the gland to reduce centrifugal forces permitting operation on high PV applications. The multiple spring design allows up to 1/16” end-play making the seal ideal for equipment with excessive end-play, split case pumps and where positive lubrication is required from an external source without diluting the pumped product.
Versatile
The seal gland is slotted to provide versatility for mounting and machined for superior strength and corrosion resistance. The narrow cross-section inboard design allows for installation on stuffing boxes with minimal radial space.
Multiple Springs
Multiple springs provide even mechanical loads for cooler operation and are isolated from the pumped product to prevent clogging. They are manufactured from Hastelloy® to provide superior corrosion resistance.
