Cooling System Parts

TABLE OF CONTENTS

Water Pumps, Centrifugal

These close coupled centrifugal water pumps are selected specifically for use in pumping coolant water in laser systems. All parts of the pump exposed to water are plastic or other inert material, and are ideal for use in distilled and deionized water systems. Pumps are available with both single phase and three phase motors, and impeller sizes as listed below. Centrifugal pumps are popular for use in laser systems because of their high water flow capability. The U.S. Laser pump line accommodates most commercial laser systems. Contact the U.S. Laser sales department for special pump requirements.


Part No. Description
N3111-1 3/4 HP single phase centrifugal pump W/ 5 1/2" impeller and 230 VAC motor.
N3111-2 3/4 HP 3 phase centrifugal pump W/ 5 1/2" impeller and 230 VAC motor
N3111-3 1 HP 3 phase centrifugal pump W/ 6" impeller and 230 VAC motor

Water Pump, Turbine

These regenerative turbine water pumps provide an effective alternative to centrifugal pumps when moderate pressure and high flow is desired. The pump housing and impeller are fabricated from 316 stainless steel with Viton seal and ceramic seat. Pumps are available with dual voltage single phase motors, which are typically much lower horsepower than corresponding centrifugal pumps due to the pups higher efficiency. For further information on these pumps for laser applications, please contact the U.S. Laser sales department.

U.S. Laser heat exchangers are fabricated from 304 Stainless steel using the spiral plate design for high efficiency. Two sizes are available, one for heat loads up to 8 KW, and one for heat loads up to 20 KW. For application on systems other than produced by U.S. Laser, contact sales department for further assistance.

Water Filters

Replacement water filters for U.S. Laser, Control Laser, Holobeam and other laser systems using 9 3/4" elements. Standard filtration rating is 5 um. For systems using shorter than standard element lengths, filter may be cut to size. Water filters should be replaced every 6 months or sooner, and should be replaced simultaneously with the deionizer cartridge.

Proportioning Valves

Proportioning valves are designed to regulate the water temperature in laser cooling systems. When properly installed, coolant water temperature can be maintained to +/- 1oC. Regulating temperature is factory preset and is not adjustable. Because proportioning valves constantly regulate the water flow, they do not suffer from the severe temperature swings typical from other systems, and are not affected by changing heat load conditions. Valve is constructed from plastic, stainless steel and other inert material to be fully compatible with distilled water. Two valves are available, one for most common laser systems, and one for high powered systems that require higher water flow. If you are unsure of the proportioning valve you need, please contact the U.S. Laser sales dept., we will be glad to assist you in selection of the proper valve.

Water Fittings

U.S. Laser stocks an extensive line of water fittings specifically for use in laser cooling system plumbing. Depending on the area of usage, fitting are available in either nylon, stainless steel, or brass. Nylon and Stainless steel fittings are used on the primary (distilled water) cooling circuit, while brass or nylon fittings are used on the secondary (tap water) side. Consult U.S. Laser sales department for help in selecting the correct fitting.
