KÄRCHER - Submersible Pumps & Well Pumps

Pumps for the Home & Garden: Efficient Water Delivery and Utilisation

Pump systems from KÄRCHER ensure reliable water delivery across a wide range of applications. Whether you need to drain a basement, manage targeted garden irrigation, or efficiently utilise service water within the home, the product range offers the perfect technical solution for every requirement.

The applications cover all tasks where water needs to be extracted, transferred, or supplied on a permanent basis:

• Drainage: Pumping out ingress water from basements, construction pits, pools, or ponds.
• Garden Irrigation: Making use of rain or groundwater from cisterns, water butts, and wells for lawns and flower beds.
• Domestic Water Use: Automatic supply for toilet flushing or washing machines within the household.
• Sustainability: Conserving tap water through the efficient use of collected rainwater.

How to choose the right pump

Choosing a pump depends on your water source and intended use:

• Submersible Pumps: Ideal for emptying flooded areas or large containers, such as pools or ponds.
• Deep Well Pumps: Specifically designed for narrow and deep boreholes.
• Cistern & Water Butt Pumps: Optimised for extracting water from rainwater storage tanks and butts.
• Garden Pumps: The flexible solution for traditional irrigation via hose or sprinkler.
• Home Water Works: For an automatic water supply with constant pressure (e.g., inside the home or for large-scale irrigation systems).

Key Selection Criteria

To ensure optimum performance, the following technical specifications should be considered:

• Delivery Head (m): The maximum vertical distance the water can be transported.
• Flow Rate (l/h): The volume of water moved per hour.
• Immersion Depth vs. Suction Height: Relevant depending on whether the pump is placed in the water (submersible) or externally (garden pump).
• Particle Size: Crucial when pumping dirty or "grey" water.
• Pressure Tank & Control: The vessel capacity in home water works for maintaining efficient pressure.

How the Systems Work

• Submersible and Well Pumps: These are placed directly in the water. An electric motor drives an impeller that draws the water in and delivers it upwards through a connection. As no suction via an air line is required, these pumps are exceptionally efficient. Sensors or float switches allow for automatic operation based on the water level.
• Garden Pumps and Home Water Works: These systems are typically installed above the water source. They create a vacuum to draw water from wells or tanks and distribute it at high pressure. While garden pumps are manually operated for irrigation, home water works feature a pressure tank and automatic control. This system switches the pump on and off automatically as water is drawn, ensuring a consistent supply for the home and garden.
