The pump body, motor, flow rate, and materials are identical. The single difference is the float switch. Knowing which type suits your sump is all you need to make the right call.

What the D15VA and D15VAGMA Have in Common
Both models are built on the same platform. Here is what they share:
- 150W single-phase motor running on standard 240V.
- Maximum flow of 140 liters per minute and maximum head of 7 meters.
- Semi-vortex, open impeller centrifugal design that handles soft solids up to 20mm in diameter.
- A special recirculation port that keeps soft solids agitated in the sump, improving the pump’s ability to clear them.
- Glass-filled polycarbonate casing, corrosion-resistant 304 stainless steel motor shell, shaft, strainer, and fasteners.
- Single mechanical shaft seal with a sand slinger lip seal for added motor protection.
- Automatic resetting thermal overload protection.
- 10-metre HO7RNF oil-resistant lead with a 3-pin power plug, ready to connect straight to a standard outlet.
- Maximum submergence of 12 meters and maximum operating temperature of 50°C.
Both pumps suit the same jobs: grey water pumping, sump emptying, septic effluent disposal, water transfer, and light slurries or factory waste.
The One Real Difference: The Float Switch Type
This is where the two Davey submersible drainage pumps part ways. If you are still weighing up Davey D15VA vs D15VAGMA: What’s the Difference and Which Submersible Pump Do You Need?, this section gives you the answer.
The D15VA uses a standard cable-type automatic float switch. The float hangs freely on its cable and rises and falls with the water level. It works well in open sumps or pits where the float has room to swing without hitting the walls.
The D15VAGMA uses a preset-length vertical column float switch, designed specifically for small or confined pits where a standard cable float cannot swing freely. The column float sits rigidly along the pump body. According to Davey’s datasheet, the D15VAGMA starts pumping at 230mm above the base and stops at 140mm above the base, preset and fixed, with no adjustment required.
That “GMA” suffix essentially signals: built-in vertical float for tight spaces.
Both switches automate start and stop based on water level, so in day-to-day use they behave the same way. The difference only matters when your sump is too narrow or obstructed for a swinging cable float.
Which Model Should You Choose?
The decision comes down to your pit size and shape. Answering Davey D15VA vs D15VAGMA: What’s the Difference and Which Submersible Pump Do You Need? is straightforward once you know your sump dimensions.
Choose the D15VA if: your sump or pit is wide enough for a cable float to swing freely in all directions without catching on walls, pipes, or fittings.
Choose the D15VAGMA if: your sump is a compact, narrow, or enclosed pit where a swinging float would jam against the side and prevent the pump from switching on or off correctly. This is common in smaller household drainage pits and confined basement sumps.
If you are unsure, measure the diameter of your pit. A narrow pit where the float cannot travel more than about 200mm horizontally is a strong sign the D15VAGMA is the safer option.
Both models handle identical flow and head demands, so there is no performance trade-off either way. Pick the switch type that fits your installation.
What If Your Davey Pump Has Stopped Working?
Sometimes the pump itself is fine but the float switch or seal has failed. Before replacing the entire unit, it is worth having the pump inspected. AEM carries out pump repairs and servicing in our Gepps Cross workshop, and we stock Davey spare parts. A repair can often cost far less than a new pump, and as an ISO9001 Quality Endorsed Company and SKF Certified Rebuilder of Pumps, our work is carried out to a verified standard.

Davey D15VA vs D15VAGMA: What’s the Difference and Which Submersible Pump Do You Need? — Is the D15VAGMA more expensive?
Yes, marginally. At AEM the D15VA is priced at $305 and the D15VAGMA at $370. The difference reflects the integrated vertical column float switch, which is a purpose-built component for confined installations.
Davey D15VA vs D15VAGMA: What’s the Difference and Which Submersible Pump Do You Need? — Can I use the D15VAGMA in a large, open sump?
Yes. The vertical float switch will still operate correctly in a larger pit. The D15VA is simply the more economical choice when your sump has room for a cable float, since you are not paying for a feature you do not need.
