The Rotan PD is an internal gear pump for the petrochemical industry. All pressure components in it are made out of carbon steel. The design pressure is in accordance to ANSI 300 lbs or Pn40. These pumps may also be ordered to meet API 676 standard ( with some exceptions). They also come with 90 degrees angular construction if required
Their capacity ranges up to 170 cubic meters per hour/750 gpm. The speed goes up to 1750 rpm and the differential pressure up to 16 bar (250 psi). The suction lift is up to 0.5 bar in 15 inch setup Hg vacuum while priming and up to 0.8 bar in 24 inch setup Hg vacuum while pumping. It can operate over a viscosity range of up to 250000 cSt at operating temperatures of up to 250 degrees Celsius (500 degrees Fahrenheit).
The pumps find application in pumping of oil, fuels, lube oil, gasoline, hydrocarbon based fluids, grease, bitumen, additives, wax and polystyrene.
