Automatic Sump Pump Kit | AMA Drainer 301, 10m Hose
Built for the job
Automatic sump pump kit for pits, cellars and yards
The KSB AMA Drainer 301 automatic pump, supplied with a hose tail, 10m of 32mm reinforced hose and a stainless-steel clip.
This FPS Engineered™ kit completes the AMA Drainer 301. KSB manufacture the pump. On its own the pump does not include a hose tail, so the kit adds one, with the hose and clip to match its 32mm outlet. The pump has its own non-return valve, so no separate valve is needed.
Part of our pump kits, sump pumps and cellar flooding ranges. Already have hose and fittings? The AMA Drainer 301 is also sold on its own.

Limits and safe use
Wastewater, surface water and groundwater with solids to 10mm. Not a sewage pump. Check the pump and float fit your sump before ordering. A pump manages water that gets in; it is not a waterproofing system.
Frequently asked questions
Do I need a non-return valve?
No. The AMA Drainer 301 is supplied with its own non-return valve.
Why does the kit include a hose tail?
The pump on its own does not come with one. The kit adds a 32mm hose tail so the hose can be connected straight away.
Will it fit a narrow sump?
The arm float is compact and suits narrow chambers better than a pendant float, but check the pump and float have room to move freely in your sump.
