Other Details

We offer Pump Gear that make use of meshing of gears to pump fluid by displacement. These pump gears are widely used in hydraulic fluid power applications and , chemical installations (to pump fluid with certain viscosity).Here, we are offering our customers’ two main variations in these pump gears. These include:

• External pump gear – Using two external spur gears
• Internal pump gear - Using external and internal spur gears

These pump gears are designed to deliver positive displacement meaning they pump constant amount of fluids for each revolution. With some gear pumps designed to function as motor or pumps, we can offer you hear precision designed and functioning spur and helical hard and ground pump gears that deliver high and constant pressure.

Features:

These pump gears are based on popular pumping principle and find usage as lubrication pumps in areas like fluid power transfer units, machine tools and as oil pumps in engines. Some of the features of these gears include:

• Range of external gear pumps made available in single/double pump configuration
• The available options include spur, helical and herringbone gears
• All gear types are designed to deliver smooth performance
• Large-capacity pumps
• Also offering smaller external gear pumps
• Close tolerances and shaft support on both sides of gears
• Gear pumps having capacity to run to pressures beyond 3,000 PSI / 200 BAR
• Well suited for use in hydraulic applications
• Tighter internal clearances that provide more reliable measure of liquid passing through pump as well as superior control over flow
• Popular for precise transferring and metering applications that involve fuels, polymers and chemical additive

Working Process:

• Use two identical gears rotating against each other
• Each gear supported by shaft with bearings on both sides of gear
• As gears come out of mesh, these create expanding volume on inlet side of pump, allowing liquid to flow into cavity where it is trapped by gear teeth as they rotate
• Liquid travels around interior of casing in pockets between teeth and casing
• The meshing of gears force liquid through outlet port under pressure

Advantages:

Some of the advantages of these gears include:

• High speed
• High pressure
• No overhung bearing loads
• Relatively quiet operation
• Design accommodates wide variety of materials

Applications:

Some of the common applications of pump gears include:

• Polymer metering
• Chemical mixing & blending
• Industrial and mobile hydraulic applications
• Low volume transfer/application
