Overview
A boat bilge that collects water is the place for this heavy duty pump, which has a liquid cooled motor with double ball bearings and a mechanical seal. A universal base plate and a choice of port sizes simplify installation.
The design targets both commercial and recreational duty, with an impeller tuned for head and flow. The spec table mislabels flow as gpm and carries odd values for lift and style, so treat those fields with caution.
Who it's for
Recreational and commercial boat owners with a battery powered system fit the pump. Home sump needs and anyone wanting automatic float switching should check other models.
Pros and cons
- Liquid cooled motor
- Double ball bearings
- Removable check valve
- Universal base plate
- Spec units contain errors
- Float switch not described
- Weight stated two ways
Performance notes
Flow depends on the impeller and the head the pump must lift against, and the listed rate applies at low head. A sealed motor with a mechanical seal protects the windings from water. Wire gauge and length matter for voltage drop on longer runs.
