Pump Operation & Performance Characteristics

Gear pump is the most versatile rotary positive displacement pump & it scores over other types of Pd pumps viz. Screw, Vane, Lobe, Tracoidal, Radial piston etc. & therefore it is used for the widest range of application i.e. loading-unloading, transfer, fuel pressurizing, hydraulic, lubrication in IC engines, Polymers metering applications etc. Gear pump can develop high pressure uo tp 210 bar in same configuration simply by tightening the working clearances & improving the workmanship, whereas in screw pump the thread length is needed to increase making the pump bulky & difficult to manufacture. In gear pump each tooth gap contributes to the capacity while in screw pump only one pitch length contributes to the capacity thus gear pumps are always cpmpact & efficient. The capacity of the pump varies directly with speed but remain constant against pressure, however some liquid always by-passes to suction due to running clearance between the casing & impeller causing slip which depends upon the differential pressure, viscosity of the liquid & the workmanship. Gear pumps are capable of handling liquids of any viscosity, th slip reduces with increse in viscocity but the frictional power increses. Though the pump has a self priming capability some net positive suction head(NPSH) is always required to avoid cavitation, this again depends on the viscosity of the liquid to be pumped & the pumping speed.

 

Internal power losses : In rotary gear pumps are of two types.The mechanical loss is the power required to overcome friction drag of all the moving part within the pump while viscous loss is power loss due to fluid viscous drag & shearing action of the fluid, this can be calculated from the graph shown here.

Horse power calculation : The bhp required to drive a rotary pump is sum of the theoretical HP & internal losses. The former is the actual work done in moving the fluid from inlet pressure condition to outlet pressure condition & is product of constant C=0.037, Capacity in M3/hr. & Pressure in Kg/CM2 or Constant c-2.3, Capacity in GPM & Pressure in PSI.

 

Gear Pump Selection & uses : RDBX/NX series pump are medium pressure pumps designed for viscous pressure application up to 21 bar. The bush bearing version type RDBX is used for clean or dirty viscous & semi viscous liquid where the shaft surface speed is less. Pump upto 2^1/2" size can be run at 1440 RPM & for higher size the speed should be reduced to 960 RPM or lower. The self-lubricated needle roller bearing type can be used for clear viscous liquid & can be run at 1440 RPM for all the sizes. This pump are ideally suited for fuel pressuring, hydraulic, medium pressure lubrication & transfer applications.

 

Inspection & testing : All pumps are assembled after due inspection of each & every parts & than they are tested for duty parameters in accordance with API-676 & JIS-B 8312-1976. Third party inspection are also offered, we are approved by following consultants & inspection agencies.

With the assistance of our dedicated workforce, we are able to bring forth a comprehensive range of RDMNS Type Rotary Gear Pump. Raw materials are feedstock for the finished products and thus it becomes crucial to source these inputs only from certified vendors. So, as a reliable name, we do the same.

Power Sped : The Hydraulic HP should be calculated by multiplying the unit HP with the duty point pressure, the viscous horse power of appropriate viscosity should be added to this from above chart. Margin for R.V. operation & Safety margin should be provided brfore fixing the drive HP. All model of RDMNS series are basically design to run at 1440 RPM up to viscosity of 200 CST however in higher sizes above 2" the pump speed is required to be reduced with increase in viscosity for this refer viscosity speed curve or consult the works. Whir reducing the speed, the pump shaft should not be loaded with heavy gears or pulley use bearing block to take up such load.

Pump Characteristics : Gear pump is a rotary positive displacement pump with positive pressure characteristics. The capacity of the pump varies directly with speed but remain constant against pressure, however due to running clearance between the casing & impeller some liquid always by-passes to suction causing sleep, which depends upon the differential pressure, viscosity of the liquid & ofcourse the workmanship. The pumps are capable of handling any vcosity, the sleep reduces with viscosity but the viscous power increases. The punp has a self-priming capability however some net positive suction head (NPSH) is always required to avoid cavitations depending upon the viscosity of the liquid to be pumped & the pump speed.

 

Internal power losses : The internal power losses in rotary pumps are of two types. The mechanical losses is the power necessary to overcome frictional drag of all the moving part within the pump While viscous losses is power requited to overcome fluid viscous drag & shearing action of the fluid, this can be computed from the graph on the opposite side.

 

H.P. calculation : The break horse power required to drive a rotary pump is sum of the theoretical HP & internal losses. The theoratical power is the actual work done in moving the fluid from inlet port to out let pressure condition & is product of Constant C=0.037, Capacity in cub. Mt./hr. & Pressure Kg/Sq. Cm or Constant=2.39, Capacity in us GPM & Pressure in PSI.

 

Pump Selection & uses : The bush bearing type of pump can be used for clean viscous liquid having sufficient lubricating value such as clean tube oil, Vegitable oil, Fish & Animal oil, Gear oil, Glycerine Hydraulic oil, Honey,ASMI & SAE lubricating oil for intermittant duty. However for continues duty pump with needle roller bearing in 'RDRN' series should be selected. For liquid having low viscosity,poor lubricating values or Containing dirts or impurities such as Crude oil, Dirty lube oil, HSD,Kerosene,LDO,Paints, Sugar solution, Turpentine, Varnish, WoodPulp. Pump with independently lubricated bearing should be selected. For liquid which tends to solidify at room temperature such as Ashphalt, Bituman, Fumace oil, Tar, Cellulose, Starch, LSHS, HPS, Molasses, Naptha, Phenol resin, RFO, Silicate, Soap solution,Viscous,Wax etc. Jacketing constructions hould be selected to facilitate the heating or the pump by steam or thermic fluid.
