Macnaught Oil Dispensing System 3:1 - OILMASTER Pump - Metered Gun
Available
The Macnaught OS50GE-01 is a ready-to-use oil dispensing system on a drum trolley, for workshops and dealerships that dispense from a 205 L drum. The TR205 trolley carries the drum. The pump goes into the drum and the hose reel and gun take the oil to the job. It uses a 3:1 OilMaster air-operated pump with a metered gun.
Pump ratio in plain words: a 3:1 pump puts out oil at 3 times the air pressure you feed it. OilMaster is the T-Series pump range, which is a proven, reliable air motor design. The T312T-01 pump has a free flow of up to 13 L/min on its own. The R-Series version of this system is the OS100GE-01. That pump has a higher free flow, up to 23 L/min. The gun is the HG20R-012E-01 metered oil control gun. Its electronic meter shows a batch total you can reset and a running total that cannot be reset, with accuracy up to +/- 0.5% of reading. It has a rigid extension, an automatic non-drip nozzle and a locking trigger, and it is rated to 6,900 kPa (1,000 psi). If you do not need to measure what you dispense, choose the OS50G-01 unmetered version. This system is for 205 L drums. For an IBC, look at the 5:1 IBC systems.
