Do I need to use a Sewage/Ejector pump if there’s no toilet in the basement?

My home has a sump pit and an ejector pit, but I'm wondering if I can just use sump pumps in both pits.

There's is no toilet or shower in the basement, so the only thing that drains into the ejector pit is the washing machine. Am I ok to just use a sump pump in that pit since they are generally cheaper than the Ejector/Sewage pumps?
