Congratulation! new type of API 610 OH2 series are successfully installed in Indonesia, etc
GW

GW series used in sundyne LMC inline compressors,

The GW liquid seal are traditional, flat faced, hydraulic balanced, OD pressurized, stationary multi-spring pusher end face mechanical seals run against a hard carbide rotor. API 682 refers to this a a type A seal. An optional PTFE Tec-ring does not produce or transmit moments to the stationary face to cause it to lose relative flatness, react to temperature extremes. or hang up due to high friction like wedge-shaped PTFE elements can. 

GW liquid seals can be used in all Sundyne pumps and assembled in any of the standard sealing arrangments: single, dural unpressurized and dural pressurized. 

The std balance liquid GW is recommended for fluids having a specific gravity between 0.6 to 1.5

The high balance liquid GWQ is recommened for light ends having a specific gravity between 0.3 and 0.6. 

The liquid lube groove GWW is specifically designed for direct drive unit use in hot water services up to 338 Cesius degree. 

without the need for external cooling piping plans such as API Plans 21,23 or 32 that would be costly to install and operate.
