KÄRCHER - Pumps for the Home & Garden

For garden irrigation, wells, cisterns & rainwater - reliable water supply with garden pumps and home pumps

KÄRCHER pump systems provide a reliable water supply for your home and garden. Pumps for the home and garden allow you to efficiently utilise harvested rainwater, well water, or cistern water for irrigation or domestic household use.

While garden pumps are designed for flexible garden irrigation, home pump systems ensure an automatic water supply for the home or garden. They maintain constant pressure throughout your pipework, and automatically supply toilet cisterns, washing machines, or professional irrigation systems with well or rainwater whenever it is needed.

Typical Applications
Garden pumps and home pressure systems are used wherever water needs to be delivered, distributed, or provided on a regular basis.

  • Irrigation of lawns, flower beds, and plants
  • Utilising harvested rainwater from cisterns or tanks
  • Drawing water from wells or reservoirs
  • Supplying irrigation systems or garden hoses
  • Providing non-potable water for household use (e.g., flushing toilets)

By using rainwater or well water, you can avoid using expensive potable water from your local supplier and maintain your garden sustainably.

Which is the right pump for me?
Choosing the suitable pump depends on your intended application and the water source.

  • For manual garden irrigation from a well or cistern → Garden jet pump
  • For automatic water supply in the home or garden → Home pump system
  • For continuous use with constant pressure and a reserve → Home pump system with pressure tank

The most important factors are delivery head, flow rate, and suction lift to ensure the pump meets your specific requirements.

Key Selection Criteria
When choosing a pump for your home or garden, the following technical specifications should be considered:

  • Delivery head (m) – the maximum height to which water can be pumped
  • Flow rate (l/h) – the volume of water transported per hour
  • Suction lift (m) – the maximum depth from which water can be drawn up
  • Power rating (Watts) – the motor performance
  • Pressure tank capacity – for home pump systems

These values determine how efficiently the pump can deliver and distribute water.

How does a garden pump work?
A garden pump draws water from a source such as a well, cistern, or rainwater tank. An electric motor drives an internal impeller, creating a vacuum that pulls the water in and sends it out through a hose or pipe. The pump is usually installed above the water source and provides the necessary pressure for garden hoses, irrigation systems, or lawn sprinklers.

How does a home pump system work?
A home pump system (Hauswasserwerk) operates similarly to a garden pump but includes a pressure vessel (tank) and an automatic control switch. The tank stores a pressurised reserve of water, ensuring the pressure in your pipes remains constant. As soon as a tap is opened or a toilet is flushed, the system draws from the tank first; the pump then starts automatically to replenish the supply. This makes a home pressure system ideal for automatic irrigation or supplying non-potable water for household tasks where potable water is not necessary.
