  • Six-Blade Design with Blade Drivers: Ensures efficient operation and extended service life.
  • Patented Needle Roller Thrust Bearing: Rated for 4,000 lbs., this feature protects against dynamic impact loads from the drive system, minimizing premature failures caused by axial thrust loads in truck applications.
  • Robust Construction: Built with O-ring seals throughout, these pumps are rated for high-pressure applications up to 400 psi (28.6 bar).
  • Non-Adjustable Internal Relief Valve: Pre-set at the factory, eliminating the need for field adjustments and ensuring safe and consistent operation.

Application Versatility

While primarily used for LPG (propane and butane) and agricultural ammonia, Z-Series pumps excel in handling other liquefied gases with high vapor pressures, such as:

  • Natural Gas Liquids (NGLs)
  • Refrigerants
  • CO2

Typical Applications

  • Bulk pump transfer
  • Propane delivery trucks
  • Transport operations
