The Whale “Tiptoe Pump” is a Self Priming Single Action Foot Pump designed for Thru-Floor mounting.

The Whale “Gusher” is a Self Priming Double-Acting Foot Pump, available with 3 mounting options (including thru bulkhead).

Whale have a number of manual pumps:
➥ Marine : Whale Pumps 12V Henderson Plumbing Bilge Diaphragm Submersible Pressure Water Systems Marine Caravan RV Shower Drain Portable Sanitation Purging Groundwater Solutions Voltage Electric

The Flipper Pump Mk4 is a Self Priming Lever Operated Hand Pump, and the V Pump is a Vertical Self Priming Hand Pump.
I used & don’t recommend hand pumps. (had both hand & foot, and electric pumps on same boat)
