The LITTLE GIANT 555602 is a self-priming transfer pump rated at 1/10 HP and designed to run on 12 volts DC. It is built for portable or mobile transfer applications where AC power is unavailable, making it a practical choice for service vans, field equipment, and battery-powered transfer setups. The self-priming design allows the pump to draw fluid without manual priming, reducing setup time on the job. Plumbers, HVAC technicians, and general service contractors install this pump when they need a compact, low-voltage solution for moving water or compatible fluids in residential and light commercial settings.
The 555602 is suited for transfer applications involving water and similar low-viscosity fluids. Its 12-volt DC operation makes it compatible with standard automotive and marine battery systems, as well as portable power supplies. Typical installation scenarios include condensate removal, tank-to-tank transfer, equipment draining, and utility service work where a self-contained pump is required without access to a standard AC circuit.
Designed as an OEM-style replacement or direct-fit transfer pump for 12-volt DC portable and mobile fluid transfer systems in residential and light commercial service applications.
Installation should be performed by a qualified technician familiar with low-voltage DC wiring practices. Disconnect and isolate the power source before making any electrical connections. Verify that the supply voltage matches the 12-volt DC rating before energizing the pump. Confirm that the fluid being transferred is compatible with the pump's internal materials prior to operation.
