Pump Selection & Uses
  • Model -DPRN- The self lubricated needle roller bearing type pump model DPRN used for clean viscous liquid having sufficient lubrcating property such as clean lube oil, Gear oil, Animal oil, Fish oil, Hydraulic oil, Honey, ASTM & SAE lub. oil.
  • Model-DPRX- This pump model is suitable for handling of Crude oil, Dirty lub oil, HSD, Kerosene, LDO, Paints, Varnish that's have poor lubricant value.
  • Model -DPRBJ- For liquid which tends to solidify at room temp. such as Bituman, Furnace oil, Asphalt, Tar, Starch this model should be selected. Jacketing const. facilitate the pump by steam.
