Installation, Operation, & Maintainance Guide
Style RKCS/D
OVERVIEW
This guide outlines the installation, operation and maintenance of the Flexaseal Style RKCS/D Cartridge Seals.
The Style RCKS/D is an engineered line of single and dual heavy duty slurry seals. RKCS denotes a single seal
model available in three versions. RKCS Version A includes an integral spring shield which shields the springs
from debris. RKCS Version B includes a bolt-on lip seal assembly for grease filled operation. RKCS Version C
adds a fluid guide sleeve to Version B’s lip seal assembly for quench operation. All RKCS versions can be made
with an optional flush connection that is compatible with API Plan 32 or other inboard piping plans. RKCD
denotes a dual seal option for the most rigorous slurry sealing applications. The RCKD dual seal is engineered
for optimum service when paired with outboard barrier / buffer liquid support systems. This guide, in addition to
the manuals provided by the pump manufacturer and the manufacturer of any auxiliary equipment, should be
read in its entirety prior to installation.
