Product description

The Tallas D-DW 400 is a high-quality, light but durable waste water submersible pump. The pump is both suitable for occasional use or for fixed placement in a basement, well or other area where clean or waste water must be automatically removed. The pump is very compact and can therefore be placed in small spaces (approx. 28 cm).

The Tallas D-DW 400 also allows you to adjust the culvert on the pump grid. As a result, you can use the pump for just clean water or a combination of clean and waste water. Adjusting the culvert affects the remaining water level once the pump shuts down. The smaller the culvert on the pump grid, the less remaining water in the room.

You can set the pump to automatically turn on at different water levels. The separate float switch cable can be attached at two places on the pump, allowing you to easily determine the level at which the pump powers on. Moreover, the pump's lever can be folded in and out as desired.

  • The pump outlet is 1.25".
  • The maximum submersion depth of the pump is 7 metres
  • The maximum head rate is 7 metres

This pump has a float switch, which means it automatically switches on and off based on the water level.

  • Switches on automatically when the water reaches 28 cm
  • Switches off automatically when the water reaches 10-15 cm
  • On manual mode (when the float switch is fixed/held), this pump will pump the water to 5 cm

Are you looking for a pump that leaves less water / switches on automatically sooner? In that case, you should choose a submersible utility pump.

Flow-rate table


The Tallas brand has been around for many years, and has always focused on the consumer market. They have come up with some handy solutions, in particular for garden irrigation and ditchwater or rainwater use. Tallas is part of DAB, and therefore its pumps meet the same high standards, although lighter materials are often used, which makes a slight difference in quality. Tallas is particularly good at providing simple solutions, with which they equip their pumps as standard, and are ideal for many consumers. For example, a built-in pre-filter that protects the pump because it stops dirt from entering it, but also light garden pumps that are fitted with a handle and footrest. This makes them easy to move and immediately available for small irrigation jobs.

Float for automatic activation / deactivation

This submersible pump is fitted with a float, which ensures that the pump is switched on and off automatically. Each pump has its own variables relating to the level at which the pump switches on or off. Robust wastewater pumps usually have a high level of activation and deactivation. They will start operating relatively late and stop relatively soon, unlike puddle pumps, which switch on sooner and switch off later. Check the pump's specifications for these variables. There are three types of floats: a floating one, which is attached to a cable; a float arm; and an integrated float. The first type needs more space because it may float in any direction, while the float arm needs less space, as it only moves up and down, and generally has higher operational reliability. Finally, there is the internal float, which is integrated in the pump and therefore needs the least space. We see these internal floats mainly in puddle pumps, because they need to operate in small spaces.
