Karcher SP 9.500 Dirt Submersible Dirty Water Pump with Float Switch and Ceramic Face Seal

Reliable Drainage for Gardens, Ponds, and Flood Situations:

The Karcher SP 9.500 Dirt delivers a maximum flow rate of 9,500 litres per hour from a 280W motor, making it well suited to draining garden ponds, emptying water butts, clearing flooded cellars, and removing water from small construction pits. It handles dirty water containing particles up to 20 mm in diameter, so sediment and debris that would block lighter pumps are not a concern here. The pump draws water down to a residual depth of just 25 mm, leaving very little standing water behind.

Ceramic Face Seal Technology from the Professional Range:

The SP 9.500 Dirt uses a Ceramic Face Seal - the same tried-and-tested sealing solution found in Karcher's Professional pump range. This mechanical seal is designed for long service life even when pumping water that carries grit, silt, or fine debris. The pump can be submerged to a maximum depth of 7 m and operates with water temperatures up to 35 °C.

Float Switch for Automatic, Unattended Operation:

The integrated float switch monitors the water level and switches the pump on and off automatically, so you can leave it running without constant supervision. The float switch position can be fixed manually if you prefer continuous operation regardless of water level. This flexibility makes the pump equally useful for one-off drainage tasks and for ongoing water management in garden ponds or sumps.

Quick Connect Hose Attachment:

The Quick Connect adapter supplied with the pump accepts 1", 1¼", and 1½" hoses via a single fitting, so you can connect to whatever garden hose or drainage hose you have to hand without needing separate adapters. The 10 m power cable gives good reach from an outdoor socket, and the connecting thread is G1 1/2. The pressure-side connection uses a G1/2 internal thread.
