  Chemical  reactions  in  the  product  chamber  of  the  pump  (mixture  of  different  substances)  and  the 
freezing of the liquid have to be avoided.  
 
 Before putting the pump back into operation, the tightness of the pump has to be checked.  
 
 
  The  operation  of  the  pump  with  nitrogen  as  driving  gas  is  possible.  In  closed  rooms  sufficient 
ventilation must be provided.  
 
 Procedure for pump return: every unit which is send to SGPPL  has to be accompanied by a RGA 
(return goods authorization) sheet. Otherwise a processing is not possible. Please contact SGPPL or 
local distributor to get the RGA file.  

All pumps returned to SGPPL must be decontaminated

 

 

 

When the pump is handling liquids higher than 122°F (50°C), avoid direct contact with 

the  pump  or  piping  system.  Use  appropriate  hand  protection  if  handling  of the  pump  or 
piping is necessary. 
 

 

Always  wear  protective  gear  (goggles,  face  shield,  acid  resistant  gloves,  etc.),  when 

removing or servicing the pump. In addition, flush the pump completely with di water prior 
to any service or maintenance. 
 

Ensure suction or discharge line valves are fully opened during pump operation

. Never 

Close a suction or discharge line valve during operation. 
 

 

Any fluctuation in supply air pressure or volume causes a change in pump discharge. 

Install a regulating valve to stabilize supply air pressure.  
 

When  pumping  a  hazardous  liquid,  ventilating  the  cabinet  is  advised  to  remove  toxic 

gas which may permeate components and build up inside the equipment.
