Triol corporation produces a wide range of submersible pumps with the capacity from 25 to 300 3day (from 157 to 18867 barrelday), and pressure from 600 to 3200 m (1968.510498.6 ft). Application of the intermediate bearings with smaller increments, as well as the upper and lower poles of hard alloys provides esp operability under the concentration of abrasive particles up to 1000 mgl (0.12 ozgal) and the particles hardness up to magnitude 7 on the mohs scale. Advantages of applying triol corporations downhole sensors: stainless steel corrosion-resistant downhole unit;base oil temperature up to 150 (302 f);nonvolatile memory. Submersible electric motors with power and voltage different from the nominal could be manufactured upon customer request. Advantages of applying triol corporations electric submersible pumps: highgrade and wellweighed technical solutionsmodern production basequality control at all stages of productionthe use of high quality materialsadvanced international technologymodern designoperation in corrosive environments triol corporation produces linear permanent magnet submersible electric motors, which is designed to drive submersible piston pumps (npg type) for crude oil production in marginal wells with temperature of up to 150c.
