Abstract
A multi-outlet fluid pump includes a housing, a motorized pump, an electrical power supply, and a self-locking thermal cutoff. In one form, the pump includes a first or primary thermal cutoff and a second or secondary thermal cutoff to prevent the pump from operating once a thermal cutoff has deactivated the pump until a user or operator has taken some affirmative action. Related methods are also disclosed herein. In some forms an indicator is provided to indicate if the thermal cutoff has disabled the pump to alert a user as to the need to unplug or reset the pump before operating the pump again.
Claims10
A pump comprising:
- a pump housing having an upper portion and a lower portion, the lower portion of the pump housing extending radially outward of the upper portion to provide stability;
- a motor disposed at least partially within the pump housing;
- an impeller connected to a motor shaft of the motor for pumping fluid;
- a first discharge for discharging the fluid pumped by the pump in a direction parallel to a longitudinal axis;
- a second discharge for discharging the fluid pumped by the pump in a direction perpendicular to the longitudinal axis;
- first and second discharge caps for respectively sealing the first and second discharges;
- a primary thermal cutoff for depowering the pump when a first predetermined temperature is reached or exceeded and a secondary or redundant thermal cutoff for depowering the pump when a second predetermined temperature is reached or exceeded;
- and
- an indicator for indicating an operational status of the pump;
- wherein the pump defines a first fluid passage and a second fluid passage, both the fluid passages being interconnected and in fluid communication with the first and second discharges, at least a portion of the first fluid passage extending parallel to the longitudinal axis and along a first portion of the motor and at least a portion of the second fluid passage extending parallel to the longitudinal axis and along a second portion of the motor different from the first portion to assist with cooling the motor during pump operation.
