IF it is a Shurflo macerator with a 1" outlet it can pump a max head of 30'....flow will be diminished at that height but it can/will pump without problems.
What does that mean........you can add another length of 1" hose without worrying it will harm pump/motor. Especially when pumping to a sewer inlet.
FloJet have similar capabilities.
I've used my FloJet to pump via 1" hose over 75' with a 2' incline.
