Triplex Cryogenic Pump
- ACD GUPD-3 Cryogenic triplex pump
- Cold ends - 1.625"
- Individual and identical fluid ends
- Externally lubriated power end
- Teflon stuffing box seals
- 1.5" stroke
- Maximum rate 121 l/min or 32 U.S gal/min @ 900rpm
- Maximum working pressure 68.9 MPa or 10,000psi
Hydraulic System
- Power from the engine in transmitted to the triplex pump throgh a closed loop
hydraulic system
- A hydraulic motor drives the triplex pump through a flex coupling
- The triplex pump is fully pressure lubricated
- The operator controls the output speed of the triplex at the control console
- The hydraulic system will be designed with all necessary relief valves, check
valves, pressure
gauges and controls
- The N2 lube system will include pump, lube oil reservoir, pressure gauge,
filter and relief valve circuit
- A steel hydraulic tank complete with filler, pressurized breather, sight glass,
drain cleanout cover and internal baffles
- There will be both high pressure and return filters
- The glycol circuit will utilize a heat exchanger
- Auxiliary circuits supply the necessary power to operate the centrifugal boost
pump and glycol circulating pump
- A hydraulically driven centrifugal boost pump delivers liquid nitrogen to the
triplex pump or returns the liquid to the tank
- The boost pump shaft is sealed using a mechanical seal
- A 100 mesh strainer will be installed on the suction side of the centrifugal boost pump
- Maximum discharge rate for the boost pump is 568 l/min or 150 US gal/min
- A liquid nitrogen strainer will be installed between the centrifugal pump and the triplex
pump with the pressure gauges located on the upstream and downstream side
Vaporizer
- Rated to 83 cbm/min (3,000 scfm) at 68,950 kPa (10,000psi)
- Heat is transferred from the engine exhaust system into a vaporizer
- Acentrifugal pump forces coolant through the vaporizer back to the reservoir
- Exhaust heat exchanger is by passed during road travel
- The vaporizer system utilizes heat from the diesel engine coolant, exhaust gases
and hydraulic power system
Nitrogen Tank
Tank :
- Gross capacty of 3,000 US gallons nominal capacity
- Net capacity of 2,850 U.S gallons
- Maximum 38 psig (262 kPa) working pressure
- Service temperature - 320°F (-196°C)

- A man way is supplied on the top of the tank to allow entry
- Tank can be loaded from either the top or bottom
- Tank will constructed with a SA240 type 304 stainless steel inner vessel and a A-607 carbon
steel outer vessel. Liquid nitrogen in the tank will be transported at -196°C (-320°F)
- Tank will be combination insulated to limit boil off rate to 0.8% per day of rated capacity
- Tank will have a safety valve (45psi) for road transport as well as a maximum pressure
relief valve (65psi)
- Rated working pressure - 344kPa (50psig) inner vessel
- Tank will have vacuum, combiation insulation, with fiberglass at ends
