'Lunar' Internal Gear Pumps

Design and working of 'Prakash' rotary internal gear pump

'Prakash' Rotary Internal Gear Pumps are simple in design and construction. They are built in various sizes and versions to suit every possible industrial application.

'Prakash' Rotary Internal Gear Pumps are specially designed for handling liquids with very low viscosity and very high viscosity, free from abrasive particles and corrosive substances. Pump bodies are designed with due consideration for porting and opening for easy entry for discharge. The gears used are special profile for most efficiency liquid transfer with absolutely noiseless operation.

'Prakash' Rotary Internal Gear Pumps are essentially constant displacement pumps, pressure range being from 0 K.g./Cm.2 upto 50 K.g./Cm.2. These pumps are exclusively used for generating pressure for oil hydraulic devices. Different types of Rotary Internal Gear Pumps can be offered depending upon required pressure application 'Prakash' Rotary Internal Gear Pumps are used for application of low to medium high pressure, high pressure in exceptional cases.

'Prakash' Rotary Internal Gear Pumps have only two moving parts. The positive displacement of liquid is accomplished by the complete filling of the spaces between the teeth of the rotor and idler gears. The only limiting factor to peak performance in an internal Gear Pump. As with all Rotary Pumps, is that the liquid pumped must be comparatively clean.

With every revolution of the pump shaft a definite amount of liquid enters the pump through the suction port This liquid fills the spaces between the teeth of the rotor and the idler The crescent on the pump head the pump head splits the flow of liquid as it is moved smoothly toward the discharge port.

The idler gear, which carries the liquid between its teeth and the inside surface of the crescent rotates on the pin supported by the pump head. The rotor gear, which carries the liquid between its teeth, travels between the casing and the outside surface of the crescent and is connected to the pump shaft.

Efficient & Dependable
These Gear Pumps have proved themselves dependable and efficient in many types of industrial pumping applications. They handle liquids ranging from light, volatile, liquified gasses to heavy viscous liquids and semi-solids.Intemal Gear pumping principle has only two moving parts-"A gear within a gear."

Suction Lifts
These Gear Pumps are suitable for suction lifts up to 25 feet (depending upon breaking point of volatile liquids). Heavy, viscous liquids are readily handled with reduction in speeds from standard ratings. Capacity is correspondingly reduced.

Drive
'Prakash' Rotary INTERNAL Gear Pumps are suitable for either direct Drive through flexible coupling or "V" Belt Drive. or through Gear Box Drive, or through Variable Speed Drives.

Maintenance
Our Internal Gear Pumps, are robust and sturdy in build. Constructed with Best of materials to give long working life. Proper maintenance and regular periodical checking will help in giving long and continuous operation life for our pumps.

Note

Pump speeds should be as under depending upon the viscosity of liquids being handled
