Tubular,Diaphragm,Pumps,Neptune,Chemical,Pump,Company,Inc Neptune Series 500 Tubular Diaphragm Pumps are engineered for viscous fluids up to 20,000 cP and for medium slurries up to 10% solids.

Features and Benefits

  • No-clog design. Straight-thru flow pattern eliminates pockets where slurries can settle.

  • Easily handles high viscosity liquids.

  • Double diaphragm is standard.

  • Capacities to 80 gph (302 lph).

  • Control options include electric or pneumatic stroke control and variable speed drives.

  • Standard units with double ball suction and discharge valves. Single ball suction valve is optional.

  • Variable Oil By-pass™ stroke adjustment mechanism provides better valve performance than variable linkage designs.

  • Viton elastomer withstands most chemicals.

  • Elastomer memory and tube shape reduce NPSH requirements, allow more viscous fluids to be pumped.
