1. Could be the seal or gaskets 

2. Please check whether any clogging or restriction is present in delivery side of pump.

3. It may need a new seal - or the existing one is not tightened correctly.  In any case, the housing gaskets should prevent external leakage.

4. If not the seal the shaft may be bend or gasket not in place,is it a drip or more.
