Seckel pear is supposed to be self pollinating. In any case, it can't be pollinated by an Asian pear.
Seckel pear is often planted to assist pollinating European pear cultivars.
I think yours just need to mature a little more. Have yours been blooming yet? Pears seem to take longer than apples to start bearing fruits. My Seckel pear just started to bloom two springs ago -- just a few flowers at first, then more last year -- which has helped my Magness pear to set a few fruits, but the Seckel didn't set fruits on their own blossoms.
The Magness is an Asian-European cross and is supposedly can be pollinated by either. I was hoping that local callery landscape pears would assist, but it bloomed beautifully for three years without bearing any fruits. I had initially planted another sugar pear called Tylar (I think? I'll have to look it up) but it died the first year due to fireblight which I thought it was resistant to. -- Point being I don't know if it needed the Seckel pollen or it wasn't mature enough.
These overly cultivated fruit trees can be tricky with their need for the right pollinators.
