Shivam Enterprise we are involved in manufacturing, quality control, selling, installing and servicing of Rotary Gear Pumps.
Shivam Enterprise offer gear pump Model "JBX/JNX" which is heavy duty flange and foot mounting type positive displacement rotary gear pump. Model "JBX/JNX" is modified version of Model "JBX/JNX" to achieve high pressure. These pumps having doubled helical finished gears and hardened & ground shafts. Due to double helical gear it prevent axial load and side thrust which help to increase life and performance of pump.
In these pumps size 1/2" to 2 1/2" are provided with thread at end of suction & delivery and they are available with foot or flange mounting, But in size 3" to 4" are provided with flange at the end of suction & delivery and they are available with foot mounting only. These pumps flange are as per standard AFA/ANSI - 300 class. These pumps can be operated up to pressure of 20 kg/cm2 with 5.0 LPM to 900 LPM flow capacity. These pumps are suitable for liquid up to viscosity of 1, 00,000 SSU and maximum temperature up to 2000C.

PUMP CHARACTERISTIC
Gear Pump is versatile rotary positive displacement pump with positive Pressure characteristic. The capacity of the pump is directly proportional to the speed but remain constant against pressure the different between theoretical and delivery capacity is the slip of the pump which depends on speed, Viscosity of liquid working clearance, Differential pressure & workman Ship. The pumps are capable of handling any kind of viscosity, the slip reduce with viscosity but the viscous power increase due to the resistance of the fluid to shear. The pump has a self priming capability however some net inlet pressure available must always equal or positive suction head NPSH is always required to avoid cavitations depending upon the viscosity of the liquid to be pumped & the pump speed
PUMP HORSEPOWER AND EFFICIENCY
The brake horsepower required to drive a rotary gear pump is the sum of the theoretical horsepower and the internal power losses. The theoretical liquid horsepower is the actual work done in moving the liquid from the inlet pressure condition to the outlet at discharge pressure. This work is done well on all the fluid of theoretical capacity, not just delivered capacity, as slip does not exist until a pressure differential offer. Note that, theoretical liquid horsepower is independent of viscosity and is concerned only with the physical dimension of the pumping elements, the rotating speed and the differential pressure.
THE INTERNAL POWER LOSSES
The Internal Power Losses are made up of two types: mechanical and viscous. The mechanical losses include all power necessary to overcome the mechanical friction drag of all the moving parts within the pump, including bearings, gears, mechanical seal etc. The viscous losses include all the power lost from the fluid viscous drag effects against all the parts within the pump as well as from the shearing action of the fluid itself.
It is probable that the mechanical loss is the major component when operating at low viscosities and high speeds while the viscous loss is the larger at high viscosity and slow speed conditions.
PUMP SPEED
Model "JBX/JNX" are recommended to run at rated speed up to 500 CST viscosity, For viscosity between 500 to 1250 CST pump speed should be reduce up to 60% of rated speed, For Viscosity between 1250 to 2500 CST speed should be reduce up to 30% of rated speed.
PUMP SELECTION
The self lubricated needle roller bearing type Model JNX used in clean liquid having sufficient lubricating property such as clean lube oil, Gear oil, Animal oil, Fish oil, Hydraulic oil, Vegetable oil. However self lubricated bush bearing type model JBX used in viscous liquids and semi viscous liquids. Model "JBX" is a bush bearing type pump which can be used for viscous liquid having sufficient lubricating value for intermittent duty; however for continuous duty, pump have needle roller bearing in Model "JNX" and it will be selected for liquid having low viscosity, power lubricating values.
