Karcher SP22.00 Submersible Dirty Water Pump with Level Sensor

High-Volume Dirty Water Drainage:

The Karcher SP22.00 is built for demanding drainage tasks, moving up to 22,000 litres of dirty water per hour with a maximum delivery head of 8 m. It handles particles up to 30 mm in diameter, making it well suited to clearing garden ponds, flooded basements, and construction pits with a volume of up to 100 m³.

Automatic Level Sensor:

The individually adjustable Level Sensor lets you set the switch-on and switch-off points to suit your conditions. The pump starts as soon as it makes contact with water and stops automatically 15 seconds after the water level drops below the sensor, reducing manual monitoring and helping to protect the motor from dry running.

Ceramic Face Seal and Stainless Steel Prefilter:

A Ceramic Face Seal protects the motor during high-volume drainage tasks and contributes to an extra-long service life. The integrated, pull-down stainless steel prefilter provides further protection for the pump impeller against larger solid particles in the water.

Auto/Manual Switch and Quick Connect Hose Fitting:

An Auto/Manual Switch lets you move between automatic Level Sensor operation and continuous manual mode without tools. The Quick Connect thread accepts 1", 1 1/4", and 1 1/2" hoses for fast, straightforward connection. A Comfortable Carrying Handle makes positioning and retrieval easy, and can also serve as a rope holder when lowering the pump.

Frequently Asked Questions

Does this dirty water pump switch on and off automatically?

Yes to both. The individually adjustable Level Sensor starts the pump the moment it contacts water, then stops it automatically 15 seconds after the water level drops below the sensor, protecting the motor from dry running without any manual monitoring. An Auto/Manual Switch lets you move straight to continuous operation whenever the job calls for it, with no tools required. The Karcher SP22.00 (1.645-852.0) gives full flexibility for either approach.

How much water can this submersible dirty water pump move?

This dirty water pump has a maximum flow rate of under 22,000 litres per hour and can clear volumes of up to 100 m³ in a single job, making it well suited to flooded basements, garden ponds, and construction pits. It handles solid particles up to 30 mm in diameter, and the stainless steel prefilter provides extra protection for the impeller against larger debris. Maximum delivery head is 8 m.

What hose sizes does this pump connect to?

The Quick Connect thread accepts 1 inch, 1 1/4 inch, and 1 1/2 inch hoses, covering the most common sizes used in drainage work. A connecting hose is included in the box. The 10 m power cable gives good reach from the pump location to the nearest power source, so there is no need to add an extension lead for most jobs.

What protects the motor on this electric dirty water pump during heavy, high-volume drainage tasks?

A Ceramic Face Seal sits at the heart of the motor protection, designed to withstand the demands of continuous high-volume pumping and contribute to an extra-long service life. The integrated pull-down stainless steel prefilter adds a further layer of defence by stopping larger solid particles from reaching the pump impeller. The IP68 protection rating confirms the unit is built for full submersion in dirty water applications.
