Neptune Tubular Diaphragm Pumps

Metering Pumps – Neptune Tubular Diaphragm Pumps

Special Application PumpNeptune Series 500 tubular diaphragm pumps are engineered for viscous fluids up to 20,000 cP and for medium slurries up to 10% solids.

Design Features/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 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.
