Macnaught BP20X-UNA BOP20 Battery Operated Pump Universal Stem Kit 20L
Available
The Macnaught BP20X-UNA is a pump stem kit for the Macnaught BOP (battery operated pump) range, set up for 20 L containers. It is the stem only: it does not include a power head, battery or charger, so it is for people who already have a BOP power head (BP20-PH) and want a stem for 20 L drums. If you need the whole setup, look at the BP20S-UNA starter kit instead.
The kit has a pump stem for 20 L containers, an Easy Control single-handed dispensing gun, a 1.5 m reinforced hose and a bung adaptor for most 20 L containers. The BOP range runs on an 18V rechargeable lithium-ion battery (BPB-20AH, 2.0Ah) with the BPC-A cradle charger, which fast charges in about 1 hour. It pumps engine oil, gear oil, hydraulic oil (up to SAE 140), ATF and engine coolant. The BOP is designed and made in Australia.
