Pump Parts & Servicing

Pump Parts & Servicing products involves the maintenance, repair, and replacement of key pump components to ensure optimal performance and longevity. Regular servicing helps prevent breakdowns, reduces downtime, and extends the life of pumps in various industrial applications. It provides efficient operation, minimizes costly repairs, and maintains consistent fluid handling performance.

AOD & AODD Pumps
AOD & AODD Pumps

Centro carries a complete selection of Air Operated Diaphragm Pumps (AOD Pumps) and Air Operated Double Diaphragm Pumps (AODD Pumps) available to purchase online. AOD Pumps are positive displacement pumps that use a diaphragm to move fluids. AODD Pumps are similar to AOD Pumps but have two diaphragms that work together to move fluids. Both pumps are available in various sizes and materials to suit your specific application. We carry a wide selection of AOD Pumps and AODD Pumps from top manufacturers, so you're sure to find the perfect pump for your application. Centro's online store is ideal for finding the right pump.

Peristaltic/Hose Pumps
Peristaltic/Hose Pumps

Peristaltic pumps, also known as hose pumps, are positive displacement pumps that use a rotating squeezing motion to move fluids through a hose or tube. Peristaltic pumps are often used in applications where other types of pumps would be unable to function, such as when pumping viscous or shear-sensitive fluids. With a wide variety of peristaltic pump models, we have the perfect pump for your specific application. Centro carries a complete online selection of peristaltic pumps, including Peristaltic Chemical Metering Pumps, specially designed for corrosive or abrasive chemicals. Shop our selection of peristaltic pumps online today.

Metering Pumps
Metering Pumps

Metering pumps are positive displacement pumps designed to move a precise volume of liquid per revolution. They are often used in industrial and commercial applications to pump chemicals, lubricants, and other fluids. Metering pumps can be either solenoid or motor-driven, and Centro carries a complete online selection of both types of pumps. Solenoid-driven metering pumps are typically smaller and more compact than motor-driven pumps, making them ideal for limited-space applications. Motor-driven metering pumps are more powerful and can handle larger volumes of fluid. No matter what your application, Centro has the metering pump to meet your needs.

Centrifugal Metallic/Non-Metallic Sealed Pumps
Centrifugal Metallic/Non-Metallic Sealed Pumps

Centrifugal pumps are the most common types used in industrial and commercial applications. They can move large volumes of fluids, making them ideal for water treatment plants, oil refineries, and other high-demand environments. Centrifugal pumps come in various styles, including self-priming and submersible models. Centro offers a complete selection of centrifugal pumps available online, making it easy to find the right pump for your needs. Whether you're looking for a centrifugal water pump or a self-priming model, Centro has the perfect pump for your application.

Sealless Mag-Drive Pumps
Sealless Mag-Drive Pumps

Sealless magnetic drive pumps are a type of pump that uses magnets to drive the impeller rather than a sealed shaft and bearings. This design eliminates the need for a mechanical seal, making them ideal for use in applications where a bearing or seal failure could release hazardous or toxic fluids. Centro’s selection of sealless magnetic drive pumps is available in various sizes and materials to suit your particular application.

Trash Pumps
Trash Pumps

Trash pumps are robust and specialized devices designed for efficiently handling and transferring water containing solid debris, such as leaves, mud, and other waste materials. These pumps are aptly named for their ability to tackle challenging tasks involving dirty or trash-laden water, making them indispensable in various industries and applications. Commonly used in construction sites, mining operations, and flood control scenarios, trash pumps excel at moving large volumes of water swiftly and effectively, even when it's laden with solid particles. With their durable construction and powerful performance, trash pumps play a vital role in maintaining clean and efficient water management systems, contributing to the seamless operation of projects that require the removal of debris-laden water.

ANSI Pumps
ANSI Pumps

ANSI pumps are centrifugal pumps that adhere to the American National Standards Institute (ANSI) standards. Key features of ANSI pumps are standardized dimensions, high reliability, ease of maintenance, and the ability to handle a wide range of fluids, including corrosive and abrasive liquids. The primary standard for ANSI pumps is ANSI B73.1, which specifies the dimensions, design, and operational criteria for horizontal end suction single-stage centrifugal pumps.


Are there different types of ANSI pumps?

ANSI pumps come in various types, including standard end suction pumps, magnetically driven pumps, and self-priming pumps, each designed for specific applications and fluid handling requirements.


What industries commonly use ANSI pumps?

ANSI pumps are widely used in chemical processing, oil and gas, pharmaceuticals, pulp and paper, and food and beverage processing.


What materials are ANSI pumps typically made from?

ANSI pumps are often constructed from stainless steel, cast iron, and various alloys to withstand chemical and temperature environments.


Can ANSI pumps be customized?

While ANSI pumps adhere to strict dimensional standards, they can be customized with different materials, impeller designs, and sealing options to meet specific application requirements.


How do ANSI pumps compare to ISO pumps?

ANSI pumps are standardized according to American standards (ANSI B73.1), while ISO pumps follow international standards (ISO 2858). The choice between the two depends on regional preferences and specific industry requirements.


How are ANSI pumps maintained?

Maintenance of ANSI pumps typically involves regular inspections, replacing worn parts, ensuring proper lubrication, and checking for leaks or other signs of wear and tear. The standardized design makes it easy to find and replace parts.


Why should you buy ANSI pumps from Centro?

Centro is a trusted supplier known for high-quality ANSI pumps that meet stringent industry standards. We offer a wide range of pump models, providing compatibility with various applications and industries. Centro offers excellent customer service, technical support, and competitive pricing, making us a reliable partner for your pumping needs.
