The centrifuge can handle maximum particle size of 500 

micron at the input. The centrifuge nozzles are .045 

inches/ 1.15 mm. However, for the safety of the pump, 

it is best if a suction filter of 150 micron is used.

Model OC-20
Flow rate .93 GPM or 55 gallons per hour
Measures 4” Diameter by 6” Tall
Supplied Universal mounting plate is 3” wide x 4” long with a flange mount with two ½ holes and a 1” NPT female coupling for affixing the return line.

Rotor holding capacity: 10.5 oz of contamination.

The flow is the key. The centrifuge can only handle 55 GPH. You need a pump that will give you 90 PSI at 0.93 GPM / 55 GPH for ultimate performance. The minimum operating pressure is 35 PSI.  The viscosity also enters into the equation, the thinner the better so heating the fuel to 140+ will also increase performance. Straight room temp vegetable will not work.

At 80 PSI and above the rotor speed is more than 7500 rpm
