Product description

This booster pump provides water whenever you need it. When a tap is opened, the device will switch on automatically and pump water from the water mains or source. This set can also be used when a specific pre-set water pressure is not reached. Then the pump will also switch on immediately for a desired result. This pump has been designed for increasing water pressure, supplying water, or using water from wells and tanks for irrigation purposes. Thanks to the water tank (an 18-litre pressure vessel), the pump does not constantly switch on/off, which means it is more energy efficient, while less power is being used. Furthermore, water hammers in the pump are prevented, which will extend the pump's life. The pump is fitted with an integrated non-return valve and a pre-filter, which ensures that solid particles in the drawn water are kept outside the pump body. The pre-filter can be opened easily and cleaned with the supplied multitool.


  • Provides sufficient pressure and capacity for one to two sprinklers
  • The hose that can be used for this pump has a diameter of 1" for the delivery connection and 1" for the suction connection
  • Draws water from a maximum depth of 8 metres
  • The maximum delivery head is 43 metres, which equals 4.3 bar output

Water tank

This pump is equipped with a water tank, which may be handy in a number of situations; for example, if the pump needs to supply water occasionally (drip watering). In that case, a pump without a tank will start pulsating (continuously switching on and off). A pump that is fitted with a tank can supply water from its tank so that the pump does not need to switch on immediately. Such pumps are very handy to use with, for instance, irrigation tubes and controlled irrigation, or for filling a toilet reservoir, which is usually also a gradual process. A second advantage of a tank is that it greatly reduces water hammer, the hydraulic shock - or ‘blows’ - that water pipes experience if a water supply point is opened hard and fast. Pumps that provide instant high pressure may increase instances of water hammer, and are therefore equipped with a (built-in) tank.


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.

Water filter

Many of our garden and booster pumps are supplied with a water filter, or one is integrated in the pump. In many cases, water is drawn from a ditch, a canal, or a local source. However, even if the water looks clean it may still contain dirt particles. Garden and booster pumps do not handle dirt particles very well, as a result of which the impeller may seize and stall. Using the water filter will stop any dirt from entering the pump.

Automatic activation / deactivation

This pump switches on or off automatically if you open or close a water point that is connected to the pump. In many cases, this feature is a considerable advantage: for example, when irrigating a garden with a hand-held sprayer, or supplying a toilet or washing machine with rainwater. It is also useful if you want to increase the water pressure in your home. Unlike standard garden water pumps, water pressure pumps - because of the difference in pressure - 'notice' when one or more water points are opened or closed. This is how the pump knows that it needs to start or stop. Standard water pressure pumps (which are mounted to a tank) are equipped with a mechanical switch, and the more advanced ones have electronic switches. Both systems have advantages and disadvantages. The mechanical switch is reliable but can either not be set or it is difficult to do so, while the electronic version can be set but is dependent on electricity.

Frequently asked questions

What is the advantage of a booster pump versus a garden pump?
A booster pump is essentially a garden pump with a number of extra components, such as:

  • An integrated pressure switch, which ensures that the pump switches on or off automatically if water supply is needed.
  • A pressure vessel (water tank), which ensures that you instantly have water at your disposal, and the pump does not need to switch on until the water in the pressure vessel starts to run low.

As a result, the booster pump does not need to switch on if only small amounts of water (a few litres) are needed.
First the water from the pressure vessel is used and supplied where it is required.
As soon as the water level in the pressure vessel is about to drop too low, the pump switches on automatically to refill it.
In addition to saving energy, the system runs much more quietly, and ensures that you always have water instantly at your disposal.

What can I use this pump for?
This pump is suitable for the following purposes:

  • Watering, spraying, and irrigating a garden or lawn
  • Hosing down a terrace, decking or garden furniture
  • Supplying water/rainwater for your washing machine, toilet, sink, shower, etc.
  • Increasing water pressure

Can this pump be connected to the existing mains water pipes in my house?
Yes, this pump can be connected to the existing mains water pipes in your house. However, this is not recommended, because the pump’s high-pressure output is not controllable. For the most suitable system, opt for the DAB e.sybox mini.

What kind of water can I pump with this model?
The Tallas D-BOOST 850 is only suitable to pump clean water, i.e. water that is free from very large solid particles (< 2 mm).
This means that you can also pump water from a canal or ditch, but subject to certain conditions:

  • We recommend making use of a suction hose with a brass connection (better filtration).
  • We recommend making use of a pre-filter (this allows for extra filtering before the water enters the pump).

In addition, the water should not be colder than 0°C and not warmer than 35°C.

Is the pump suitable for continuous operation?
No, the pump is not suitable for continuous operation.

How should the pump be installed?
The pump and the entire connected system need to be protected against frost and inclement weather conditions.
Therefore, place the pump in a dry location with an ambient temperature from 5°C to 40°C, to allow the motor to cool sufficiently.
Furthermore, all connected pipes must be absolutely watertight and airtight to prevent damage and loss of performance.

The water to be drawn in by the pump is situated at a level lower than nine metres. How do I handle this?
Generally, garden pumps and booster pumps can draw in water from a maximum depth of nine metres.
If the water is occasionally at a depth lower than nine metres, you will need to use a borehole pump, which is placed in the well and usually has a delivery head of 50 metres and over.
Check our range of borehole pumps.

What happens if the water from the source is finished?
This is a water-cooled model pump, which means that it cools itself with the water it pumps.
When the water from the source is finished - for example, if the water level has dropped below nine metres - the pump will normally keep running with no water supply.
This is referred to as 'dry running' and may cause the pump to become overheated, which could ruin it.

This pump is not fitted with a dry-running protection system, which can be ordered separately. Please refer to the dry-running protection system.

Is the pump suitable for a drinking-water system?
Yes, this pump is made of technopolymer, and is therefore suitable for a drinking-water system.

Is the pump supplied ready to use?
Yes, you can start using the pump immediately, but it is not supplied with accessories such as a discharge hose.
If needed, these can be ordered conveniently from our webshop together with your pump.
