pump not sucking water

I have a 170DM5 - Stenner Pumps Chemical Feeder and it is not sucking water into suction side. The roller turns but not water moving. I have new #5 tubes.

Have you expanded the roller assembly when you changed the tube ? If you have a quick pro head the rollers must be expanded when you change tubes. Are the ferrules installed correctly ? Check the foot valve / strainer. It could be clogged
