Macnaught R-SERIES 5:1 Stub Pump R500S-01
Available
The Macnaught R500S-01 is a 5:1 air-operated stub oil pump for medium to large workshops and mobile applications. The 5:1 ratio is the choice for high flow rates over longer distances. It gives this pump a free flow of up to 32 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 5:1 this pump pushes oil through longer hoses and thicker oil than the 3:1 and 1:1 models while keeping a high flow. 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. Go to the 10:1 R1000S only if your hose run is very long, as it moves less oil.
