Industrial Gas Pumps        
Instruction for installing units                  
Industrial gas poumps are mainly used for air separation products:filling of liquid oxygen,liquid nitrogen,liquid argon,liquid carbon dioxide,air supply systems.The units are mainly single row,double row and three-row reciprocating pumps.Refer to each parameter table for specific paraments.                                                                                                                                                                                                                                                           Its flow is 30-5000 L/h and its maximum exit pressure is 35.0MPa.An electromagnetic adjustable speed motor,or a fixed rotating speed motor,or a variable frequency and variable speed motor ,or an explosion proof motor or an explosion proof variable frequency motor can be equipped as per actual requirements.                                                                 
Intructions for installing units        
1,The pump inlet shall be close to the storage tank to the greatest extent;        
2,From the pump to the storage tank,the liquid inlet and air return pipeline shall be kept upward sloping to make the air inside the pipeline  return to the storage tank.Reverse "U-shaped"elbows are prohibited in the liquid inlet pipeline,and "U-shaped"elbows are prohibited in the air return pipeline;         
3,Ball valves or brake valves shall be used for the liquid inlet pipeline ande the air return pipeline.Stop valves shall not be used.Elbows shall be reduced to reduce pipeline resistance;        
4,Thermal insulation shall be performed for the liquid inlet pipeline and the air return pipeline;        
5,In order to keep the safety of  the unit or auxiliary pipelines and facilitate operation,a liquid otlet/air outlet pressure interlocking device with automatic control can be equipped;        
6,After the reciprocating pump is operated for 600 hours,the motor dierction can be changed to make the transmssion case rotate in a reversed direction so as to enhance the service life of teh reansmission case.

Performace features                  
A such pump has classic desigen and stable performances[;its service life can reach 20 years                  
A high vacuum jacket pump head is used,and the vacuum degree reaches 10-5torr so as to reduce cold loss;                  
Its seal is reliable:the service life of packing can each 150,000times/cylinder and the service life of the pistion ring is as long as 300,000 times/cylinder;                  
An auxiliary gas sealing device can be equipped to further enhance the service life of  the sealing element;                  
Maintenance is convenient:it merely takes two hours to perform a routine maintenance                  
The pump can be continuously operated for 24 hours
