Shivam Enterprise offer gear pump Model JRN/JRB heavy duty foot mounting type positive displacement rotary twin gear pump with flange (class 150# ASME/ANSI B16.5).
The Pump consists of a double helical refined gear along with a hardened grind finished shaft. The double helical gear prevents axial load & side thrust which increases the life and the performance of the pump.
The pump can be operated up to maximum pressure of 10 Kg/cm2, flow capacity from 10 LPM to 2080 LPM and are suitable for maximum temperature up to 200°C & maximum viscosity up to 1,00,000 SSU.
MODEL SELECTION:
Model JRN/JRB: for clean viscous liquid having sufficient lubricating values such as Vegetable Oil, Animal Oil, Fish Oil, Clean Tube Oil, Gear Oil, Hydraulic Oil, Gycerine, Automotive & Diesel Engine Oil etc. For intermitted duty, the bush bearing type of pump (JRB) is used and for continuous duty, needle roller bearing type of pump (JRN) is selected.
Model JRN: for liquid having low viscosity, low lubricating values, impure/dirty Crude Oil, dirty Lube Oil, HSD Kerosene, Sugar Solutions, LDO Paints, Wood Pulp, Varnish, Turpentine, the pump with independently lubricated bearing is selected.
Model JRB: the pump with the jacketing construction for liquid which tends to solidify at room temperature such as Bituman/Asphalt/Tar, Furnance Oil, Starch, Molasses, Naptha, Soap Solution, Wax etc. The jacketing construction in the pump facilitates heating of the pump by steam or thermic fluid.
FEATURES
- Heavy duty gear pump design for continuous application.
