Measure how high and far your system needs to move liquid. Then compare pumps by priming methods and flow control types.
High-Pressure Metering Diaphragm Pumps for Chemicals with Locking Lever
 |
An adjustment dial with a locking lever allows for easy flow control. These metering diaphragm pumps can be used with pressures up to four times higher than standard chemical metering diaphragm pumps. They're often used for general purpose dispensing of chemicals such as ammonia and acid-washing solutions. The adjustment dial alters flow rate in 5% increments of the maximum flow. Pumps are self-priming and create suction to draw liquid upward. Do not run dry or use with solids.
Repair Kits—Repair kits include a pump head assembly, valves, a diaphragm, and mounting hardware.
