STIHL TPA 20 Cordless Water Pump - Tool Only

The STIHL TPA 20 Cordless Water Pump is a compact, portable solution for watering gardens and allotments using collected rainwater, or removing water from small pools, tanks and barrels. Powered by the STIHL AS System's 10.8 V AS 2 battery, this lightweight pump offers cordless convenience for everyday water transfer without the need for a mains power supply.

With a maximum pressure of 2.2 bar (32 PSI) and a flow rate of up to 2,200 litres per hour (580 US gallons per hour), the TPA 20 makes it easy to move water where you need it. Using a fully charged AS 2 battery, it can pump approximately 550 litres in 15 minutes - equivalent to around five rainwater tanks or 50 watering cans.

The versatile 2-in-1 design supports both irrigation and water removal. For draining tasks, the removable pump base converts the TPA 20 to a flat-suction function, making it useful when emptying small pools or carrying out cleaning work. The base can be removed without tools, allowing you to switch between applications quickly.

Designed for straightforward operation, the TPA 20 features three power levels to adjust pressure and flow rate to suit the task. Three selectable operating intervals of 5, 10 or 15 minutes provide added flexibility, while dry-running protection automatically switches off the pump when no water is detected.

A double sealing system and integrated filter help protect the pump during use. The filter is easy to remove and clean, making routine maintenance simple and helping keep the pump ready for your next watering or draining job.

Please note: This is the tool-only version, supplied without a battery or charger. A compatible STIHL AS 2 battery and charger must be purchased separately if you do not already own them.
