4 bends in sump pump PVC ok?

I'm replacing my backup sump pump with a basement watchdog 'big dog' today.

In order to make the cover of the pit fit I will have to add a bend in the pvc so that the pvc goes through the slot in the lid.

My question: do bends in the pvc pipe add much drag to the water flow? My rise is about 10 feet and the pipe already has three bends in it (1) a 45 degree to the wall, (2) 45 degree up the wall, (3) 90 degree out of the house.

That is normal. The following pic is only the primary pump but you will see two 45 degree elbows and you know there is a 90 degree elbow discharging it out the wall.
