    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.
