Kärcher SP 16.000 Dual Flat Suction Submersible Pump for Dirty Water, Flow Rate: 16,000 l/h, Immersion Depth: max. 7m, for Dirty Water with Particles up to 20mm in Size, Residual Water Height: 1mm

Great pump. I use it to empty my hot tub, it does the job in 20 minutes and gets pretty much every last drop of water out. A lot of other pumps leave about 3-5cm of water. I really like the push fit hose connection. You do need to use a wide diameter hose (5cm) to get the full flow rate.

Bought as an emergency sump pump to cope with recent floods, as drains were overrun and blocked. Took a bit of setting up to make sure that the float switch didn't foul, but after that was fixed it's run very well. Not sure if the flow is quite as high as advertised - but I've got it attached to 25m of hose and it emptied by 1m3 sump in roughly 10 seconds - so fast in fact that I needed to drill extra holes in the plastic liner I used to line the sump to stop excess grit working through. The pump has handled debris of various sorts well too and has a decent length of power cable too.

Good product. Used it now a few times In my inspection pit fast extraction which is great when not using it stick it in clean water To flush it to keep in good condition long cable Which is good lowering it into my pit 6 Foot deep can be used as a puddle pump or large amounts of water

Let's cut right to the chase: if you've ever had a flooded basement or needed to empty a hot tub fast, you know the biggest pain isn't just the water, it's the last little bit you have to mop up. That's where the Kärcher SP 16,000 shines. This thing is the real deal—a heavy-duty pump that doesn't mess around.

Bought to pump out a large very large pond, debri aswell quite impressed especialy the price, the flow and force that the water cpmes out is very good easy to handle , comes with different connectors

Incredible flow rate, emptied a huge swimming pool in no time at all. Karcher quality is second to none. Highly recommended, don't be tempted by inferior, cheaper pumps, you get what you pay for.

Ideal

Trying to empty a pool - won’t pump last 10 inches of water up 6 feet. Not as good as expected and no better than basic screwfix pump. Overall very disappointed

Have not used yet. Bought it for emergency use only, and hope never to use it. But the quality is obvious.
