I was descending out of 18;000 ft as pilot flying. When hydraulic pumps were selected to high we received a right system hydraulic pressure low light. Checking gauges; right hydraulic pressure was zero with an abnormally high quantity indication. I told the FO to get out the QRH. I notified ATC that we had a hydraulic problem and might have a problem making the assigned crossing. I was given relief from the crossing restriction. I said we were working the problem and would advise them. I then notified the FAs of the situation and would keep them advised. As we worked the QRH it was noted that we would have to do a manual gear extension which would mean stopping straight ahead on the runway. I then advised ATC and would be stopping on the runway and would have to be towed off. I asked that the safety equipment be rolled as well. I then called the FAs. I then made a PA to the passengers and let them know what was going on. The approach was normal and the emergency gear extension accomplished. I landed at bug +5 with a soft touchdown. Rollout was normal and I could feel the gear door bumpers dragging on the rwy. I stopped on centerline approximately 10000 ft down Runway XXR. I made a PA stating for everybody to remain seated. The safety trucks rolled up and we were contacted by them. I asked them to check around the outside of the aircraft looking especially on the right side by the gear. They said they noticed a fluid on the ground but everything else was good. I then talked to the FAs and let them know what was going on. I then made a PA to the passengers to advise them that we were going to be waiting for a tug to come and tow us back to the gate and apologized for the inconvenience. It took approximately 40 minutes for the tug to show up and tow us back to the gate.Right hydraulic fluid loss when pump selected to high resulted in a right hydraulic low pressure light and loss of right hydraulic system.
MD80 Captain reported a right hydraulic system failure which necessitated a manual gear extension with a normal landing and a tow off the runway.
