Macnaught R-SERIES 3:1 Stub Pump R300S-01
Available
The Macnaught R300S-01 is a 3:1 air-operated stub oil pump for medium to large workshops and mobile applications. It has a free flow of up to 23 L/min and is rated for oils up to SAE140, coolants, kerosene and diesel.
The R-series is Macnaught's heavier-duty air-operated oil pump range. It has a heavy-duty aluminium and steel air motor with large exhaust ports to prevent icing, and it comes with an airline lubricator and a 2" bung adaptor. The ratio is how much the pump multiplies your air pressure at the oil outlet. A higher ratio gives more push for long hose runs and thick oil, but usually less oil per minute. A lower ratio usually moves more oil with less push. At 3:1 this pump balances flow and push. It handles thicker oil and longer hoses than the 1:1 R100T. This is the stub version. It is the pump only, with no drum suction tube, and it is best for wall or remote mounting. The ST003AS suction tube set is sold separately. If your hose run is longer, step up to the 5:1 R500S, rated for up to 32 L/min free flow.
