Zenith Pumps met the challenge and designed a rotary external gear pump of unique precision and simplicity. Manufacturing techniques were developed to hold tolerances to +0.00005" minimizing internal clearances to assure accurate and precise metering. The pump’s simplistic design of only three moving parts - two metering gears and a drive shaft–provided long life and easy maintenance.
The tough and wear resistant H series Zenith pump series is designed for high temperature and viscosity service.
Features
  • High Accuracy - Stable, repeatable flows are assured even under varying conditions of pressure, viscosity and temperature
  • High Temperature Capability - Operating temperatures to 950° F (510° C)
  • High Volumetric Efficiency - Maximum efficiency is achieved with optimum operating clearances and assured under pressure by built-in alignment dowels
  • Minimum Pulsation - Unique design offers virtually pulseless flow without valves or flexible elements to hinder performance
  • Maximum Life - Only three moving parts; components are through-hardened tool and die steels to 64 Rc or better. Replaceable sleeve bearings for low-cost rebuilds
  • Precision Construction - Ground and lapped components for close of operating clearances
