..............only if its drain to waste
most likely..... Some are high pressure low volume and others low pressure high volume. A good pump manufacturer will list specs such as flow rates at head heights etc.
For instance look at the tables on this page.

FWIW I've gone through quite a few danner pumps and I'm not impressed with them. They are step above ecoplus, but with the money spent rebuilding them and messing around with issues I could have bought Iwaki's from the get go.
But its probably easier just to get a larger cheap pump. And its cheap insurance to get a spare.
