Extra check valve?

While reading another thread, I had a thought.
I just finished re-plumbing my '73 Tradewind, and in the process, couldn't remember if the pump had a built in check valve on the outlet side. The pump is the old PAR pump that is working just fine after I re-sealed the diaphragms. (had a very slow seep out past one of them when under constant pressure)
Anyway, I went ahead and plumbed a check valve just downstream of the pump.
My question .... will this extra check valve cause the pump any trouble? It certainly doesn't seem to be hurting anything yet.
