PAINT AND COATINGS MANUFACTURING: TiO2
Optimizing Diaphragm Performance
When Pumping Titanium Dioxide
BY JAMES FARLEY
This critical component in paint and coatings production can be
challenging to handle, so a next-generation diaphragm design will
help improve AODD pump protection

here is scarcely a painted surface in the world - be it house, portrait or child's
toy - that has not been covered by a paint containing titanium dioxide, or
TiO2
the mineral ilmenite.
The reason that TiO2 is used as a white pigment in most of the world's paints and
coatings is simple: it possesses the highest refractive index of any material in the world.
In other words, because TiO2
does not absorb visible light, any paint containing it has
a high level of opacity, or hiding power, which is a needed characteristic for a highperforming
paint or coating.
Because of its indispensability as a paint and coating component, the global TiO2
market is a robust one, which is buoyed by the fact that it is also commonly used in
the production of plastics, paper, pharmaceuticals, inks, food colorings and cosmetics,
among many others. In fact, according to market research firm Research and Markets
and its Global Titanium Dioxide (TiO2
) Market 2019-2023 report, the TiO2

market will
experience a compound annual growth rate (CAGR) of four percent through the year

market make it imperative that paint and
coatings manufacturers identify and deploy a pumping technology that can reliably
introduce it to the production process and then transfer the finished paints and coatings
in the high volumes that are required to meet the demands of strict composition
characteristics and production schedules. This article will illustrate how positive

, a fine white powder that is produced most often through the mining of
displacement (PD) air-operated doublediaphragm
(AODD) pumps have risen to
the fore as a first-choice technology for
TiO2
pumping, with a new generation
of diaphragm designs adding to their
ability to deliver optimized TiO2
performance.
THE CHALLENGE
In paint and coatings plants, TiO2
is
introduced to the production process
as a high-viscosity slurry. AODD pumps
have become an obvious choice for TiO2
transfer because they can handle abrasive
liquids of higher viscosities that may
also contain large solid particles. Their
method of operation also gives them the
ability to self-prime, deadhead and run
dry with low shear, which enables them
to quickly reach and maintain desired
flow rates throughout the entire duration
