SNP High-Speed Sliding Vane Pumps High-Speed Stainless-Steel Pumps For Caustic or Corrosive Liquids

SNP Series pumps, which are part of the Stainless Line of sliding vane pumps, are capable of meeting the demands of high-speed liquid applications because they offer the flexibility needed to handle caustic and corrosive liquids at varying temperatures, pressures and viscosities. This allows them to be used in various loading/unloading and transfer applications, while the stainless-steel construction of the SNP model makes its ideal for handling a variety of corrosive or caustic fluids, which is a crucial consideration in the manufacture and shipping of biodiesel.

With flow rates of 4 to 32 U.S. gpm (15 to 121 L/min) and standard operating temperatures of -25°F to 350°F (-32°C to 177°C), the SNP1.25 and SNP1.5 pumps offer the best combined characteristics of sustained high level performance, energy efficiency, trouble-free operation and low maintenance cost.

Blackmer fully Integrated Unit Assemblies are the pre-engineered and pre-designed drop-in pumping solution. These unit assemblies, include motor, gearbox, baseplate, coupling safety covers, and a SNP 1.5-inch Stainless Steel Sliding Vane Pump. No alignment required with these pre-configured fully Integrated Unit Assemblies as they are ready for immediate drop-in installation.

Features and Benefits

  • 316 stainless-steel construction with metallized carbon sleeve bearings and non-metallic vanes for longer life with corrosive products
  • Use of nonmetallic sliding vanes and reversible carbon discs within the pump reduces friction and eliminates galling
  • Optional commercial mechanical seal with stainless steel, carbon, and PTFE construction
  • Optional Triple-Lip Cartridge Seal available 
  • Shaft stuffing box accommodates most standard aftermarket mechanical seal configurations
  • Jacketed pump head option for high temperature operation
  • Pump design and operation minimizes shear and agitation
  • Symmetrical bearing support assures even loading and wear for long life
  • Adjustable relief valve protects pump against excessive pressures
  • Advantages of sliding vane technology:
    • Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
    • Excellent self-priming and dry-run capabilities
    • Sliding vane design provides sustained performance and trouble-free operation
    • Easy maintenance: vanes can be easily replaced without removing the pump from the piping system
    • High suction lift and line-stripping capabilities
    • Low maintenance and low life-cycle costs

Applications

  • Corrosive or caustic fluids:
    • Sugars
    • Syrups
    • Beer
    • Beet juice
    • Cider
    • Flavor extracts
