How to choose a Kärcher pump?

Whether for irrigation, domestic drinking or drainage, Kärcher offers the right water pump.

Use submersible models to pump water from ponds, cellars or pools. Pumps superficial Karcher are applied to household water supply and filling of the pipeline. Depending on the degree of pollution, models for clean or dirty water should be selected.

Types of Kärcher pumps

Distinguish between submersible and surface pumps for Karcher water. The first type is installed above the surface of the liquid, only the hose is brought down. Submersible models come in 4 different types:

• for watering;
• centrifugal;
• self-priming;
•  pressure.

The name of the submersible models speaks for itself. They completely sink under water, work to pump out the liquid, pushing it through a special tube to the surface. Depending on the purity of the source, different modifications of the devices are selected. 

Submersible clean water equipment is used for pumping liquid from wells, draining the pool. The Kärcher dirty water pump (depending on equipment) handles impurities with a particle size of 20 mm to 30 mm. 

Tight stainless steel filters protect the equipment from blockages that could block the impeller. The submersible pump for dirty water is designed for domestic sewage, industrial wastewater, liquids with large diameter impurities.

Basic types of Karcher submersible equipment:

• drainage;
• well;
• for wells;
• water fountain

Each type has a separate lineup, which presents products from a German company. These are Karcher pumps for watering from a barrel, drainage electrical installations, self-priming options and others.

The submersible pump is easy to choose according to the application. They are divided into two main categories:

1. Borehole pumps, which are distinguished by powerful pressure, a strong supply jet, therefore, are laid to a great depth. 
2. Pumps for barrels, pools, small tanks. They are usually designed for less pressure, making the models suitable for depths of only a few meters.
