No, inflation is defined as the rate of increase of general prices in a particular market, however that market is bounded.
> It is caused by an increase in the money supply relative to the value it represents.
Because the markets for different goods and services are to a certain extent distinct, and because populations of different levels of wealth demand different goods and services, redistribution always causes increase in the supply of money chasing goods and services demanded by the group benefiting from the redistribution (and a decrease on the other side), at least in the short run (in the longer run, its effects on overall productivity, which depend on other details, will determine the effects.) As a result, you'd expect redistribution to cause some inflation in the market for goods and services demanded by the beneficiaries of the redistribution.
