Macnaught OILMASTER 5:1 Stub Pump T512S-01

The Macnaught OilMaster T512S-01 is a 5:1 air-operated stub oil pump for medium flow over longer distances. 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. 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 you need more oil per minute at 5:1, the R-series R500S gives up to 32 L/min, but it uses more air.
