I thought the pump wasn't always a sure sign of growth?
Been doing about 15 reps on seated raises with a barbell. I know standing is supposed to work another area or the whole calf but is seated not enough? Sure I read somewhere that seated was enough. Never liked standing although I did do them regularly. In the Gym I use a proper machine. I feel a bit stupid asking people to jump on my back for donkey calf raises [ no machine for these]
If your goal is hypertrophy then you want a pump to get best results.
Seated are good for the soleus but not enough to develop the complete calf.
Standing will develop the complete calf.
Standing options - any calf exercise with the leg straight, not bent at knee like being seated.
Standing calf machine
Leg press
1 leg calf raises
Donkey calf
