Fit check

Is it right for my water supply?

A quick check before you buy.

  • Rain, surface and storm water

    Good fit

    These pumps are designed for rainwater, surface water and storm water: cellars, garages, ditches, pits, ponds and sump emptying.

  • Slightly dirty water or small soft solids

    Good fit

    The open impeller handles clean or grey water with up to 10% small soft solids or 1% fine solids. Expect some wear from sand, grit or hard solids.

  • Sewage, effluent, slurry or stringy waste

    Not this one

    We don't recommend these dewatering models for raw sewage, stock effluent, grease traps, hair, stringy materials or slurries. Davey's vortex, cutter and grinder pumps are made for those.

  • Automatic float

    Good fit

    The D25A has a preset float switch that starts the pump as water rises and stops it at a safe level. Leave room in the sump for the float to rise and fall freely.

  • Pit or sump depth

    Consider

    The range has a 10 m lead and 12 m maximum total head.

  • Emptying a swimming pool

    Consider

    These small dewatering models suit emptying pools, but they're not for recirculating or filtering pools or spas, and never with people in the water.

Common questions

Does it switch itself on and off?

Yes. The D25A has a preset float switch, so it starts as water rises and stops when it has pumped down to the pump's safe operating level. The float needs room to move freely.

What water can it pump?

Clean or grey water of neutral pH with up to 10% small soft solids or 1% fine solids. Some wear should be expected with hard solids, sand or grit. We don't recommend it for sewage, effluent, grease traps or slurries.

How much water can it move?

The D15A to D40 range has capacities to 240 lpm and 12 m maximum total head. The D25A is the 0.25 kW model with a 1½" F BSP outlet; the performance curve shows the figures for each model.

Can it run when it's only partly under water?

These single case pumps rely on water around the motor shell for cooling, so they should only run partly submerged for short periods up to 10 minutes. Don't run the pump dry.

What warranty does it have?

The D25A comes with a 24-month warranty.
