Introducing Tuthill’s new range of process gear pumps: GlobalGear successor of ST series.
   
   
   
   
 
 
    Tough gears
    The rotor & idler gears are made of ductile iron, which can handle the stresses of high-viscosity and high-pressure operation.
       
    Strong shaft design
    Most models employ high strength 4140 alloy steel shaft. This along with oversized shaft diameters, ensures a strong, reliable shaft.
       
    Robust bearings
    Oversized ball bearings. Side-top port option.
       
     
       
     
   


       
   
    Modular ports
     
   

Several port ‘styles’ are available to match your piping needs. Some examples of port options are ‘side-to-side’ or ‘side-top’, NPT or BST tapped, ANSI 125#/150# or 250#/300# flanged, ISO PN16 or PN40 flanged.Moreover, each pump size has numerous ports size option to minimize piping losses.
       
       
       
    Modular seal chamber
     

Modular seal chamber provides a choice of packing, mechanical seal or cartridge seal, without having to change any major components gear, shaft & bearing.


     
   
       
       
    Standard shaft sizes
      Allow you to use seals you probably already have for other rotating
equipment. And this applies no matter where you are, because GlobalGear pumps are available with your choice of nominal inch or metric shaft sizes.
       
    Spare drive modules
      The back pullout design allows you to stock a spare drive module
instead of a complete pump.

A: Typical time to replace complete pump.

B: Typical time to replace GlobalGear drive module.
     
     
     
     
  In-line seal access
  Reduces seal maintenance time. The seal can be removed without disturbing the piping or shaft alignment.
 
   
 





A: Typical time to replace seal in pump without inline seal access feature.

B: Typical time to replace seal in GlobalGear pump.

 

     
 


     
  No piping changes
   
GlobalGear mounting dimensions match those of most other gear pumps.  
       
       
       
    No drive changes
     
     
 

At any given speed, the GlobalGear’s flow rates match those of most other gear pumps.

A. Other gear pump at 780 RPM.
B. GG130 at 780 RPM.
