Tubular Diaphragm Pumps
From 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.

• Spring-loaded discharge (Models N3 and N7 only). External back pressure valve is not required.
