Macnaught OilMaster T312S-01 3:1 Stub Oil Pump

The Macnaught OilMaster T312S-01 is a 3:1 air-operated stub oil pump for medium flow over larger distances. It has a free flow of up to 13 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 3:1 this pump balances flow and push. It handles thicker oil and longer hoses than the 1:1 T112S. 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. For even more push on a longer run, the 5:1 T512S moves a little less oil. If you need more flow at 3:1, the R-series R300S moves more oil.
