Madden diaphragm chemical metering pumps are designed for tough jobs where chemicals must be pumped all day long, year round. Engineered materials are used for the wetted end to pump virtually any chemical, from acids to caustics. Even viscous liquids and suspended solids can be metered and pumped with precise accuracy.
Repeatable accuracy of +/- 1% over a 10:1 turndown ratio is maintained with the stroke adjustment control located conveniently on the top of the chemical metering pump.
The simple mechanically actuated diaphragm design eliminates irritating hydraulic systems and packing glands used in many chemical metering pumps. Large bearings and shafts, continuously lubricated with a bath of oil give many years of dependable service. Precision bronze worm gears and steel worm drive shafts convert motor rpms to linear piston pumping power. Replacing worn parts is quick and easy, and accomplished with common tools.
Chemical metering pumps by Madden are heavy duty industrial grade, using standard industrial 56 frame motors and worm gear reducers to produce reliable chemical pumping power designed to provide years of dependable service. Features include...
Chemicals are added to many processes in industrial plants to produce a desired outcome, such as changing the pH of water. Adding too much of the chemical will waste money and it could also reduce the desired outcome that was required in the first place. A chemical metering pump is designed to enable the operator to control the rate of chemical addition to make sure the results are within the limits of the specifications for the process.
