Description
The 86/87 seals are cartridge mounted mechanical seals, designed for
ease of installation and reliable operation. No seal setting dimensions
are required. Rotatable centering tabs provide proper alignment. The
flexible stator design compensates for inadvertent misalignment of the
seal chamber face. Multiple springs provide uniform face loading and
are external of the pumpage, resisting clogging or hang-up. Installation
according to the following steps will assure long trouble free life of
the 86/87 seals.
Equipment Check

• lock out motor and valves.
• wear designated personal safety equipment.
• relieve any pressure in system.
• consult plant MSDS files for hazardous material regulations.

1.4 Make sure the shaft or sleeve and the seal housing face are
clean and free of burrs, cuts, dents, or corrosion that might cause
leakage past the sleeve packing or gland gasket. See Figure 1 & 2.
