Technology

How do Precision Gear Pumps work?

The design utilizes high AGMA standard external spur gears enclosed within a close tolerance housing assembly. This provides you the precise volume of fluid dispensed per shaft revolution. The housing is constructed from a precision ground and lapped three-plate assembly. This assembly is aligned with dowels to allow close control of operating clearances. This construction method in combination with several proprietary internal features is what ensures precise, pulseless and reliable flow under varying process conditions. When Zenith pumps are coupled with a pre-packaged, integrated, closed-loop speed control and a compact motor driver assembly (AC or DC), Zenith is able to provide the most precise and flexible metering gear pump system on the market.

Demanding applications require a precise volume of fluid dispensed – reliably, accurately and consistently. The Zenith precision metering gear pump is the industry standard for true precision metering for challenging applications in a wide variety of industrial processes.

Applications
Zenith Pumps

Zenith pumps and systems are used in a range of applications in a variety of markets. Generally, Zenith pumps meter chemical solutions; yet the requirements of each generic metering function can be industry specific. Zenith pumps applications are classified as dosing, filling, injection, coating, extruding, spraying or spinning.

Zenith pumps feature a wide operating flow, pressure and temperature range capable of handling abrasive, corrosive, hot, cold, viscous, toxic and shear sensitive fluids.

  • Minimum – Maximum Flow Rate = 0.16 – 27,000 cc/rev
  • Maximum Viscosity = 1,000,000 cps
  • Maximum Pressure = 4000 psi
  • Maximum Temperature = 900F

Benefits

THAT GO STRAIGHT TO YOUR BOTTOM LINE

For Accuracy, Reliability Pulse-Free Metering Performance, here are some of their key advantages:

Stable, repeatable flows are assured under varying conditions of temperature, viscosity and pressure.

Unique design offers virtually pulseless flow without valves or flexible elements that add complexities, increase cost and hinder performance.

A variety of pump heads and drive combinations are pre-configured to provide you a range of standard options.

Unparalleled mechanical precision, combined with closed-loop accuracy, ensures exact volume per revolution without expensive flow meters.

Only three moving parts and hardened abrasion resistant materials provide excellent wear, corrosion and self-lubricating performance.

Years of practical application experience, backed by a technical staff with a variety of technical credentials, eliminates the guesswork.
