What are the 3 major types of chemical pumps used?
2
In the world of chemical production, there is an
interplay of processes, precise measurements, and
robust machinery. A significant contributor to
this system is the chemical pump. These reliable
devices tirelessly facilitate the movement of
liquids and harsh slurries to ensure seamless
operations and effective output.
3
Given the range of chemicals and tasks at hand, a
single type of pump design is insufficient. This
is where three primary types of chemical pumps
step in Centrifugal pumps Metering
pumps Positive displacement pumps Each type
possesses advantages tailored to requirements.

1. Centrifugal Pumps The Backbone of Industrial
Operations Picture a spinning carouselthis
serves as the concept behind centrifugal pumps,
widely used in the chemical sector. These pumps
employ a rotating impeller with blades that
generate force within the liquid, propelling it
outward through the discharge chamber.
5
Centrifugal pumps exhibit traits for diverse
industrial needs. Their capacity for flow rates
makes them ideal for large-scale fluid transfers
in industries with substantial liquid movement
requirements. Their uncomplicated design also
minimizes maintenance demands, ensuring
performance and upkeep.
6
Centrifugal pumps are also well known for their
cost-effectiveness, making them a popular choice
for a range of applications where financial
considerations are crucial in selecting equipment.
7
Centrifugal pumps have roles in industries,
particularly in transferring large amounts of
low-viscosity liquids like water, acids, and
alkalis. They are also essential for supplying
process equipment such as reactors and mixing
tanks to ensure a flow of materials needed for
manufacturing processes. Centrifugal pumps also
play a role in cooling systems and circulation
loops by moving fluids to maintain optimal
operating temperatures in industrial machinery
and processes.

2. Metering Pumps for Precision Pumping
Solutions When accuracy is crucial, metering
pumps come into play. These pumps excel at
providing controlled and precise volumes of
liquid, making them indispensable for tasks like
chemical dosing, sample injection, and supplying
instruments.Metering pumps possess features that
are essential for accurate fluid management
across different industries.
10
They provide flow control, ensuring reliable
dosing of fluids essential for maintaining
accurate chemical processes and guaranteeing
product quality. Metering pumps have a flow rate
range, allowing them to handle large liquid
volumes effortlessly and providing flexibility in
various application scenarios.
11
Not just that, but metering pumps are also
self-priming. They can draw liquid from low-level
reservoirs, enhancing their versatility and
efficiency in handling tasks in industrial
settings.
12
Metering pumps play a role in industries,
especially in dosing chemicals for vital
processes like water treatment, food processing,
and pharmaceutical manufacturing. Their ability
to dispense volumes of reactants accurately makes
them indispensable in reactions, ensuring optimal
reaction conditions and high product quality.
13
Metering pumps are essential for delivering
samples for analysis in laboratories, enabling
measurements crucial for research and quality
control purposes. Metering pumps stand out for
offering solutions across diverse industrial and
laboratory applications.

3. The Unyielding Force of Positive Displacement
Pumps When it comes to dealing with liquids,
slurries, or handling pressure variations, positiv
e displacement pumps stand out as the top choice.
These pumps utilize mechanisms like pistons,
gears, or screws to trap and move volumes of
liquid in a reliable manner, regardless of the
system's pressure.
16
Positive-displacement pumps possess features that
are crucial for a wide range of industrial uses.
They are recognized for their ability to handle
pressures effectively, making them ideal for
tasks that demand pressure levels, such as
hydraulic systems and applications involving
high-pressure fluid transfer.
17
These pumps excel at managing liquids and
slurries, delivering performance even with
challenging fluids commonly found in industries
like oil and gas production, wastewater treatment
plants, and food processing facilities. Their
self-priming nature enables them to function
efficiently when liquid levels at the inlet are
low, enhancing their adaptability and usefulness
across environments.
18
Positive displacement pumps play a role in
transferring thick substances such as resins,
paints, and adhesives. Their precision in
dispensing volumes of viscous chemicals is
particularly valuable in sectors like chemical
manufacturing and processing, as it ensures
consistent dosing for optimal product quality.
19
Positive displacement pumps also play a role in
powering high-pressure tasks such as filtration
systems and injection molding. Their ability to
manage fluids and maintain pressure levels is
essential for efficient operations and production
processes. Whether it involves moving materials,
dispensing chemicals, or supporting high-pressure
functions, positive displacement pumps are
crucial for handling fluids in industrial
settings.

21
Selecting the Right Pump and Finding the
Balance Choosing a chemical pump requires an
assessment of various factors relevant to the
industry and application. Key considerations
involve evaluating properties like viscosity,
abrasiveness, and compatibility with pump
materials to ensure performance and durability. 
22
Understanding the flow rate is important as it
determines the amount of liquid transferred per
unit time, while knowledge of pressure
requirements is vital for selecting a pump that
can effectively overcome system resistance.
23
In addition, considering the requirements of the
application, whether it involves dosing,
transferring, or high-pressure tasks, helps
customize the selection of pumps to meet the
needs of the intended usage scenario. This
ensures reliable handling processes in industrial
settings.
24
By having a grasp of the advantages and
limitations of each pump type (centrifugal,
metering, and positive displacement), along with
the expertise of a reputable manufacturer like
IDEX, you can guarantee that your chemical
operations run efficiently and effectively.
25
Exploring Advanced Features and Factors Beyond
Basics While the main categories of chemical
pumps provide a foundation, there are advanced
features and considerations that cater to
specific industrial requirements. For instance,
magnetic drive pumps enhance handling by
eliminating contact between the motor and liquid
chamber, reducing the risk of leaks and
contamination
26
 Ideal for corrosive chemicals, these pumps offer
improved safety and dependability. Submersible
pumps like IDEX's Proline series offer a solution
for transferring liquids from tanks or pits while
operating fully submerged in the liquid. With
applications ranging from wastewater treatment to
material management, these pumps offer solutions
for fluid control.
27
Since safety remains a priority, taking into
account factors such as compatibility, leak
prevention, and explosion-resistant features is
also necessary. IDEX addresses these concerns by
offering pumps that comply with safety
regulations for handling environments,
emphasizing safety in chemical pumping activities.
28
Conclusion Having knowledge of the
characteristics and applications of the three
types of chemical pumps (centrifugal, metering,
and positive displacement) will help you navigate
the selection process more effectively. Remember
to take into account specialized features and
safety standards and explore offerings from
manufacturers to find the ideal pump for your
specific chemical processing needs.
