FOR THREADED PORTS FOR BALL-TYPE PORTS FOR COPPER TUBE FOR PRESS-FIT PORTS ACCESSORIES MODULAR HOSE Nozzle Extensions Choose a nozzle extension that suits your applica- tion. Short projections are more compact and are less likely to be knocked out of position by swarf or vibration, while longer extensions are easier to aim, produce a more laminar flow and shoot farther. Some experimentation will be required to achieve the optimum setup. A Word About Pumps The most common coolant pump on CNC machine tools is a single-stage centrifugal pump. They are normally designed to move high volumes of water at low pressures (typically 3 - 20 psi). Multi-stage centrifugal pumps are capable of higher pressures (typically 20 - 200 psi) while still producing high flow rates. Positive displacement pumps are used for very high pressure applications (up to 2000 psi) and are generally used with small diameter orifices due to their lower flow rates.

Flow Rate through Orifice in US gal./min. (see table on pg 2) Orifice Diameter in inches Example: Pump Pressure: 40 psi Orifice Diameter: .160" Flow Rate: 4.0 US gal/min. V = 24.5 x 4.0 = 3828 ft./min. .1602 Contents 3
