 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.
Precise
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.
Long Life, Low Upkeep
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...
- Heavy duty aluminum
gear box and pump
body
castings
- Precision machined and bolted assembly
- Wetted end
parts made from a selection of corrosion resistant materials
- Thick Nylon reinforced diaphragms for tough pumping service
- Industrial grade 56 frame electrical motors are available
to meet any enclosure and power supply requirement.
Why use a chemical metering pump?
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.
