• Pump curves are nominal values. Pressure values for centrifugal pumps are differential pressures
between the inlet and the outlet of the chiller.
• Pump performance results were obtained with no restrictions on the return to the system or with
any options installed. For example, utilizing the DI option will result in a 0.5 gpm flow reduction .
• Specifications obtained at sea level using water as the recirculating fluid, at a 20°C process
setpoint, 25°C ambient condition, at nominal operating voltage. Other fluids, fluid temperatures,
ambient temperatures, altitude or operating voltages will affect performance. See Section 3.
• Thermo Fisher Scientific reserves the right to change specifications without notice.
