7120 Series

 

 

Flows to 235 GPH, Pressures to 3000 PSI This rugged, leak-free hydraulic diaphragm style metering pump is designed for precise metering and long term dependability. Its time-proven drive and stroke control mechanism combined with a wide variety of wet end head designs deliver superior value for any application. 

 

 

Key Features Includes: 

  • Full motion stroke length control mechanism gives 0-100% sinusoidal flow output with infinite increments of adjustment.
     
  • Fully sealed drive and control mechanism with diaphragm breather to eliminate atmospheric contamination and assure extended service life.
     
  • Flooded lubrication. No lubricator pumps required.
     
  • Simple in-line componentry easily serviced without major disassembly.
     
  • Built-in hydraulic by-pass valve, make-up valve and bleeder valve for hydraulically balanced, trouble-free operation. Rugged diaphragms constructed of PTFE elastomer or metal with precise hydraulic balance for safe accurate metering.
     
  • A broad selection of economical head, diaphragm and valve designs to handle any liquid metering application.
     
  • Material options to handle any liquid.
     
  • Performance And Dependability.
     
  • Metering accuracy with ±1% over a 10:1 flow range.
     
  • Drive components carry a two-year warranty.
     
  • Flat diaphragm style reagent head assemblies are available with rugged.
     
  • PTFE diaphragms for general application or metal diaphragms for extreme temperature, pressure or liquefied gas service.
     
  • Check valves have O-ring compression type seals and are easily removed for maintenance. (In most instances without disassembly of piping.) 

 

The HYDRATUBE® style, developed in 1967, has a proven track record. Its straight-thru design makes it an excellent choice for high viscosity or slurry products. Optional valve designs are available for slurry service. Standard HYDRATUBES use VITON®, HYPALON® or NORDEL® elastomers. Teflon® PFA 

HYDRATUBES® and/or Teflon® primary diaphragms are optional.
