Operating hand pump with electric motor

Hi you all,

Have seen several videos which demonstrate the adaptation of a PCP hand pump operated by an electrically powered cranking system. Does anyone know of a source for plans for the construction of this rig? Or does anyone know of a source which sells such a rig with or without the hand pump?

While viewing the operation of several of these pumping rigs provided an excellent view of how they are constructed, plans which described the specs and materials used would eliminate a lot to guess work in the construction of one of these. Size of electric motor, source of bell cranks, type and size of other parts would be most useful. For example I am thinking that using a 12 volt automobile starter motor would all for its use in the field.
