1. A pumping system for pumping one out of a number of fluids with varying viscosities, comprising:
- a positive displacement pump; and
a control for operating the positive displacement pump;
the control comprising viscosity compensation data;
wherein the viscosity compensation data relates to at least one of the number of fluids such that the control instructs the positive displacement pump to operate based on the viscosity of the one of the number of fluids.

Abstract
A pumping system for pumping one out of a number of fluids with varying viscosities. The pumping system may include a positive displacement pump and a control for operating the positive displacement pump. The control may include viscosity compensation data. The viscosity compensation data relates to at least one of the fluids such that the control instructs the positive displacement pump to operate based on the viscosity of the fluid.

9. A method for operating a positive displacement pump with one out of a number of fluids with varying viscosities, comprising:
-
determining the slippage rate of the positive displacement pump for each of the number of different fluids at a given flow rate;
determining the compensation rate for each of the number of different fluids;
placing one of the number of fluids in communication with the pump; and
pumping the one of the number of fluids at the given flow rate based upon the compensation rate. - View Dependent Claims (10, 11, 12, 13)

14. A beverage dispenser, comprising:
-
a plurality of fluid sources with a plurality of fluids of different viscosities;
a dispensing valve;
a positive displacement pump to pump one of the plurality of fluids from the plurality of fluid sources to the dispensing valve; and
a control for operating the positive displacement pump in response to the dispensing valve;
wherein the control comprises compensation data related to the one of the plurality of fluids such that the positive displacement pump compensates for the viscosity of the one of the plurality of fluids during operation. - View Dependent Claims (15, 16, 17, 18, 19, 20)
