The Neptune 500-VS High-Viscosity Chemical Metering Pump is designed to accurately measure viscous fluids up to 5,000 cP such as polymers and other thick liquids.

The Variable Oil By-pass™ stroke adjustment allows an adjustable time delay between the end of the suction stroke and the beginning of the discharge stroke. This delay permits the ball to seat fully before pumping resumes even in the heaviest liquids, so pumping accuracy remains high.
