    • Leads: 14 AWG w/2 pin Molex connector. Compatible with Aquatec power supply
    • Temp limits:  For user safety, optimal performance, and maximum motor life, this motor is equipped with a thermal protector that limits motor shell temperature to 145F (63C)
    • Duty cycle: See heat rise graph
    • Mounting plate:  Powder coated steel mounting plate
    • Dimension: 4” x 4” x 9”
    • Weight: 6.3 pounds

Thermal shut-off: 

• For user safety, optimal performance, and maximum motor life, the motor is equipped with a thermal protector that limits motor shell temperature to 145F (63C).  Under high loads when the motor shell temperature reaches 145F the thermal breaker would open after 60 minutes, and the motor would require 30 minutes of cooling before it restarts.  Power cycling should be limited to 6 times per minute.

Performance Data

All performance testing is conducted in a controlled environment with 70F (21C) ambient and water temperature, and 30 PSI inlet pressure.  Voltage is fixed at 24 VDC.  Both performance and heat rise data will vary with changes to environmental and operating conditions.  An additional inlet pressure increase will result in similar increase in discharge pressure.  Maximum inlet pressure rating is 80 PSI (5.4Bar).

Shaded areas within the charts below denote performance points at which the pump can run continuously, without thermal breaker interruption.  Within the unshaded areas, the pump will require periodic shutdown for motor cooling.

The lower curve of the Heat Rise graph plots the highest current where this pump model can run without a cooling requirement.  The upper curve represents the highest current draw of this pump model, under which the thermal breaker would open after approximately 60 minutes and the motor would require approximately 30 minutes of cooling before it restarts.  Power cycling should be limited
