Answer to Question 1

In a positive drive there is no design slippage of the belt at all. Most belts have teeth and use sprockets with teeth.

Answer to Question 2

(1) Zero leakage of fluid.
(2) Capable of higher pressures.
(3) Better suited for chemical sealing.
(4) Little or no shaft wear.
(5) Less maintenance, No adjustment necessary.
(6) Less friction, more efficient.
