Macnaught OILMASTER 5:1 Stub Pump - Underground Mining T512-01-11

The Macnaught OilMaster T512-01-11 is a 5:1 air-operated oil pump in zinc construction, made for underground coal mining applications. It has a free flow of up to 11 L/min and is rated for oils and coolants up to SAE140.

The OilMaster T-series uses Macnaught's OilMaster air motor design. It has a polymer air motor and uses less air than the R-series, but it moves less oil at the same ratio. It also has a built-in pressure relief valve. 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. It is supplied as a bare pump with a 2" bung adaptor only, and the ST003AS suction tube set is sold separately. If your site is not an underground coal mine, the standard 5:1 T512S is the usual choice. If you need more flow at 5:1, the R-series R500S gives up to 32 L/min.
