Some rough estimates...If assuming the kit consist of Magom's smallest standard rams with12 mm bore, and about 5 mm rod. (Best guess is that this size, at least, are used, but to know 100% you need ask them) Their new small pump gives up to 18-20 bar (~kg/cm2)
2 rams pushing; 2x 1.13 cm2 x 18 bar = 40 kgs
2 rams pulling; 2x 0.93 cm2 x 18 bar = 33.5 kgs


Rough estimates as mentioned, but 6 & 10 kgs should not be a worry
