Q: Where can the pump be installed?

Great for use in kitchen and bathroom. It is also the great partner of camper, sprayer, garden sprinklers, fertilizers, sprinkler faucet and agricultural irrigation as you like.

Q: Can this pump have a nozzle connected to it and be used as a “on demand” pump?

This pump turns on when you plug it in, so if you connect a hose or tube to the pump with a valve on it, it will stay primed. So when you open the valve it will pump. I don't believe it has a pressure valve that turns the motor off! So if it's always running, it might fail faster. I'd recommend using some sort of pressure valve that can sense pressure and turn on or off depending on pressure.

Q: Is this pump rated for continuous duty?

Continuous use will overheat, it is best to let it rest.

Q: Is there a minimum outflow rate the pump can operate at? Would thai be suitable for a single outlet RO filtration system from an unpressurized tank?

Ok, here's the fact. My bucket to do list is huge. The install of the pump we're talking of I don't have it in yet. But to your question I've read up on the pump and yes since the flow rate is adjustable by a "set" screw it just goes to reason that you can set it to the minimum as well as to the maximum with out causing another issue. The case in point with me is the galley faucet, not a one of us has found the reason, why is the hot water flow so drastically low than the cold water flow. When we turned on the cold water it flows very good, with the switching to the hot water, (it's a single control faucet) the hot water is just a trickle. So we figured if this pump is installed between the hot water supply line and the faucet it will bring the issue to an end. I'll close this with in my career decision I became what's known as a computer systems analyst so if I drop the word computer and have left systems analyst I become able to problem solve matters such as plumbing, electric not so much so, but yet skilled enough to solve the "things" that can be so annoying that it gets our goat.
