High-Accuracy Metering Diaphragm Pumps for Chemicals

Image of Product. Front orientation. Diaphragm Pumps.

These diaphragm pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, cleaning fluids, and electropolishing solutions, they have an adjustment dial that alters flow rate in 2% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. They can run dry but are not for use with solids.

Long-Life High-Accuracy Metering Diaphragm Pumps for Chemicals

A 316 stainless steel housing provides corrosion resistance for a long life in harsh environments. These diaphragm pumps meter a consistent amount of liquid within ±2% of the maximum flow. Often used to pump water-treatment chemicals, they have an adjustment dial that alters flow rate in 2% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. They can run dry. Do not use with solids.
