September 2016:

 

PRO presents a completely  new design for a submerged piston pump for cryogenic liquids

 

In  cooperation with ILK in Dresden, PRO is pro- moting the    newly developed pump for media such  as  helium, hydrogen, LNG and liquefied

air gases.  Versatile,   extremely compact   and simple, for a variety of flow rates and pressures and  with  a   minimum of  energy consumption and heat leaks by utilizing linear electric drives.

​

For the patented design the thermal coefficients

of  expansion of  the  different  materials are of utmost  importance  as  the  complete system is permanently exposed to the cryogenic liquid.

​

A dedicated system allows for a precise control

of pressure and flow rate.
