I would not use 1 1/2" for a drain of that length, but the critical dimension is from the fixture trap to its vent, not from the sink to the pump.
: Hi,can I use a 1 1/2" pvc pipe to drain a sink ? or it has to be 2" ? the distance from the sink to the sewer pump that I'm using is 20ft. thanks for your help
