Type 2: Multi-purpose, non-pusher elastomer bellows seal available in single, double and balanced arrangements
GR1/1C: General duty reservoir that can withstand pressure up to 16.3 bar while providing buffer/barrier fluid to a dual-seal arrangement
GR2/2C: General duty reservoir that can withstand pressure up to 30 bar while providing buffer/barrier fluid to a dual-seal arrangement
GR3/3C: General duty reservoir that can withstand pressure up to 73 bar (stainless steel) or 62 bar (carbon steel) while providing buffer/barrier fluid to a dual-seal arrangement
GP-S/GP-D: Non-API gas control panel for filtering, regulating and monitoring gas supply to gas-lubricated pump seals
Cyclone Separators: Typically used in an API Plan 31 arrangement and incorporated in the seal flush line (API Plan 11 ) from the discharge of the pump
Safeunit™ Ultima: Specially designed to control seal water flow and pressure in extreme conditions
Safeclean: Removes impurities and particles, providing clean seal water for stuffing boxes and mechanical seals
