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.

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.

Frequently Asked Questions

What does a float switch do and how does it benefit me?
A float switch ensures that your pump automatically turns on or off at a certain water level. This is very convenient if you wish to use the pump in rooms that are regularly submerged. After all, when using a float switch, you won't have to manually turn the pump on or off every time there is water in the room. Moreover, the pump is also equipped with a float switch, which means it can be set to both automatic and manual operation modes.

If I use the float switch, at what water level will the pump automatically turn on and off?
You are completely free in deciding when the pump automatically turns on or off by fixing the float switch to a specific height on the pump. The minimum power on level is around 280 mm. The pump will automatically power off at a water level of 100 to 150 mm. In order to ensure that the room doesn't maintain a water level of 100 to 150 mm once the pump powers off, the pump is often placed in a small pit. This pit ensures that the pump is placed at a slightly deeper position in the room, ensuring continued pumping until a water level of 100 to 150 mm is reached in the pit. In this way, the rest of the room will be pumped dry and there will only be some remaining water in the pit.

In what situations can I use this pump?
You can use the pump in the following situations:

  • The draining of your basement and/or crawl space
  • As a permanent setup to automatically drain your basement/crawl space once a specific water level is reached
  • The draining of your basin
  • The draining of your pool
  • The draining of your pond or ditch
  • The draining of a construction well and other wastewater wells

Can this pump be placed in small spaces?

This pump requires a space with a minimal diameter of 28 centimetres. As a result, this submersible pump can be placed in almost any space.

Is the pump delivered ready for use?

Yes, this pump is supplied with all components required for direct use. The drain hose (which you can order from us) is equipped with the appropriate couplings that can be screwed onto the pump.
