Macnaught IBC or Pod Mounted Oil Dispensing System - T500 Pump
Available
The Macnaught OS950IM-01 belongs to Macnaught's OS950 range of IBC oil systems, which use the R500 5:1 pump. Macnaught makes these for 1000 litre totes with a metal support frame, so you can pump oil from the IBC to the point of use. The tote is not included in the OS950 range.
The pump in the OS950 range is the R500S-01, a 5:1 R-series pump. It has a free flow of up to 32 L/min and is rated for oils up to SAE140, coolants, kerosene and diesel. R-series pumps have a heavy-duty aluminium and steel air motor with large exhaust ports to prevent icing. 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. An IM012E in-line meter is available depending on the model. The IM012E is an oval gear meter with a digital display and a resettable batch total, with accuracy of +/-0.5% and a flow range of 1-30 L/min. The OS900 range has the T512 pump, which has a free flow of up to 11 L/min. In Macnaught part numbers, B means no gun, G means an unmetered gun, GE means a metered gun (the meter is built into the gun) and IM means an in-line meter (the meter is fitted in the hose line).
