contaminating the seal quench chamber. The SLD Seal Support System is a
single point lubricator and is not designed to supply more than one seal quench
cavity at a time.
Synthetic Lubricant
The specially formulated Flowserve lubricant (DS-920-OG) lubricant has been
selected because of its inert nature to acids and caustics and proven ability to
promote seal face survivability during periods of marginal hydraulic equipment
operation. The lubricant complies with Occupational Safety and Health Standards
(OSHA) regulations 29 CFR 1910.120 related to "Hazardous Waste Operations
and Emergency Response". To obtain best seal life, alternative lubricants
are not recommended. Contact your nearest Flowserve Sales and Service
Representative or Authorized Distributor for possible substitutes that will not
invalidate your mechanical seal warranty when used.
