In Grinding, Coolant Application Matters - SME
Coherent-jet nozzles give better grinding performance because they concentrate the coolant into the grinding zone, allowing the pores of the wheel to be fully filled, and thereby minimize the applied flow rate. A dispersed jet pumps air and coolant into the grinding wheel, displacing some of the fluid with air.

Abrasive Flow Machining Systems | Winbro Flow Grinding
A flow grinding machine serves several functions. First, it must be able to pump the abrasive media at either a specified pressure (PSI/MPa) or flow rate (cubic inches per second/liters per minute). Second, it must be able to clamp and seal the fixture between the upper and lower media cylinders, in a two-way flow system.

A word about coolant pumps. The most common coolant pump on CNC machine tools is a single stage centrifugal pump, normally designed to move high volumes of water at low pressure (typically .2 to 1.4 bar). Multi stage centrifugal pumps are capable of higher pressures (typically 1.4 to 14 bar) while still producing high flow rates.
