US LASER CORP: Product Catalog
 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.

 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.

refrigerant. 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.

 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.
