Aquatec 5852-7E12-J584 1.2 GPM 60 PSI 3/8 inch JG 120V Delivery/Demand Pump with Cord

Can this go into a carpet extractor

what is the max inlet pressure?

We currently have a pump that was installed by the r/o installer, very noisy, sounds like jack hammering. Is this pump quiet when pumping?

Does this pump have to be primed? I will be using it to pump water from a stream up to my RV
