What is Flowserve?
Flowserve is an industrial manufacturer that sells and services the equipment used to move, control and seal fluids in demanding operations. Its portfolio centers on pumps, valves, mechanical seals and sealing systems, actuators and instrumentation, plus energy recovery devices — the hardware that keeps material flowing safely through plants where a failure is costly or dangerous.
What the company actually offers
- Product sales — standard and engineered pumps, valves, seals, actuation and instrumentation. The company describes its range as covering both routine and highly engineered duties.
- Services and repairs — maintenance and lifecycle support for installed equipment, including turbomachinery service that expanded through the acquisitions of Greenray and Allen Steam Turbines.
- Specialists and consultants — direct access to application and engineering expertise rather than a purely catalog-based sales model.
- Literature and brochures — technical documentation to help buyers specify equipment.
Recent additions point to where the portfolio is heading: the acquisition of Trillium Flow Technologies' valves division broadened its engineered and nuclear valve offering, and the LMX Cartridge Lip Seal targets top-entry mixers where contamination control matters. A cryogenic submerged motor pump series addresses LNG regasification.
Who it is for
Flowserve is aimed at industrial buyers, not consumers: plant engineers, reliability and maintenance managers, EPC contractors and procurement teams in sectors such as oil and gas, chemicals, power generation, water and desalination. If you need a single pump for a light duty, a distributor catalog may serve you faster. If you need a pump, seal and valve package engineered together for a high-consequence process — with service support over a multi-decade asset life — this is the type of supplier you would shortlist.
How to judge fit
| Your situation | What matters most |
|---|---|
| New plant or major upgrade | Engineered-to-order capability and full system scope |
| Aging installed equipment | Repair, retrofit and legacy fleet support |
| Strict purity or emissions limits | Seal and containment technology |
| Tight budget, simple duty | Standard products and local distribution |
A practical next step: start from the specific duty — fluid, temperature, pressure, flow rate and failure consequence — then check whether Flowserve lists a matching product family and whether service coverage exists near your site. Compare that against at least one alternative supplier on lead time and local support, since for critical equipment the service network often decides the purchase as much as the hardware does.

How do I find the right Flowserve pump for my industrial application?
Start with the application, not the catalog. Flowserve's own site organizes its portfolio around pumps, valves, seals, actuators and instrumentation, with product sales, services and repairs, and specialist consultants as the main entry points. The pump selection process works best when you can describe the fluid, the operating conditions and the consequence of failure before you look at any model.
What to define first
- Fluid: clean or abrasive, corrosive, viscous, volatile, or containing solids.
- Duty point: required flow rate and head, plus the range you actually operate across.
- Environment: temperature, pressure, indoor/outdoor, hazardous area classification.
- Reliability need: continuous process, intermittent transfer, standby, or critical shutdown service.
- Constraints: footprint, noise, energy use, maintenance access, and spare parts strategy.
How to use the Flowserve site
The product portfolio separates standard pumps from engineered pumps, which is the first real fork in the road. Standard pumps suit common transfer duties where a catalog model meets the duty point. Engineered pumps are aimed at tougher fluid handling and control challenges, so expect a more involved specification and quotation process. Seals and sealing systems sit alongside pumps because the seal often determines whether a pump survives in a given fluid. Actuators, positioners and instrumentation matter when the pump is part of a controlled loop rather than a simple on/off duty.
A practical route
- Write a one-page duty specification using the categories above.
- Browse the pump categories to narrow the technology type, not the model number.
- Use the literature and brochures section to check materials, seal options and performance coverage.
- Contact a representative or a specialist consultant with your duty specification and ask for a recommended range and the trade-offs between options.
- If the pump is for an existing installation, ask about services and repairs and about upgrade paths before assuming a like-for-like replacement.
Whose experience is this?
The page evidence describes Flowserve's portfolio, service offerings and recent acquisitions, but it does not contain a user review or a video walkthrough. The steps above are general selection advice, not a documented Flowserve procedure, so treat them as a framework to bring to a sales conversation.
Decision criterion
If your duty point is stable and the fluid is benign, a standard pump from the portfolio is usually the faster and cheaper route. If the fluid is abrasive, corrosive, cryogenic or high-purity, or if downtime is expensive, go straight to engineered pumps and involve a specialist early. For a worked example: a plant moving cooling water at a steady rate can start with standard pump categories and confirm the seal arrangement; a plant handling a crystallizing or solids-laden stream should lead with the seal and materials question, because that is where the selection usually fails.
For a second opinion on pump and seal fundamentals, Hydraulic Institute publishes industry guidance, and ASME covers relevant codes and standards.
What services does Flowserve offer for repairing and maintaining existing pumps, valves, and seals?
Flowserve's service offering centers on Services & Repairs, backed by specialists and consultants who support equipment over its operating life. The site frames this as lifecycle support rather than one-off fixes: repairs, parts, upgrades, and technical advice for pumps, valves, seals, and automation equipment already in service.
Practically, that means owners of installed flow-control equipment can use Flowserve for:
- Repairs and refurbishment of pumps, valves, and seals, including legacy equipment.
- OEM parts and replacement components, which matters when a non-original part could affect fit, performance, or safety.
- Upgrades and modernization of existing assets instead of full replacement — the page's pricing signals mention "upgrade," which suggests retrofit and upgrade paths are part of the offering.
- Specialists and consultants for troubleshooting, application questions, and maintenance planning.
- Lifecycle services for turbomachinery, expanded through the Greenray and Allen Steam Turbines acquisitions, aimed at aging gas and steam turbine fleets.
For a maintenance planner at a plant running older pumps or valves, the value is having one vendor for repair, parts, and engineering advice rather than coordinating separate machine shops and parts suppliers. The trade-off is that OEM service typically costs more than a local repair shop; it makes most sense for critical, high-consequence equipment where downtime or a failed repair is expensive.
Next step: Identify the specific pump, valve, or seal model and its service history, then contact a Flowserve representative through Flowserve to ask about repair options, parts availability, and whether an upgrade is more cost-effective than replacement.
How can I contact a Flowserve specialist or consultant for help with a critical flow control challenge?
Contact Flowserve through the "Specialists & Consultants" path listed on its site, or start with "Product Sales" if you already know the equipment category. For a critical flow control problem, the fastest route is usually a direct conversation with a local sales or service representative rather than a web form.

H3 Practical steps
- Identify the challenge type: pump, valve, seal, actuator/instrumentation, energy recovery, or a service/repair issue.
- Use the relevant portfolio page to narrow the product family before contacting anyone. This makes the first call much more productive.
- Request a specialist or consultant through the site's contact paths, or ask for the nearest authorized service center if the issue is an outage or repair.
- Have these details ready: fluid, temperature, pressure, flow rate, duty cycle, failure history, and site constraints.
H3 When to choose which contact route
| Your situation | Best first contact |
|---|---|
| New project or equipment selection | Product Sales |
| Existing equipment failing or degrading | Services & Repairs |
| Complex system, compliance or performance problem | Specialists & Consultants |
| Need drawings, manuals or technical data | Literature & Brochures |
A concrete example: a plant operator with a recurring seal failure on a high-value mixer should gather operating data, then ask for both a sealing specialist and a service representative. That combination often surfaces whether the fix is a different seal design, a repair, or a process change.
If you are unsure where to start, contact Product Sales and ask to be routed to the right specialist for your application.
Where can I download Flowserve product literature, brochures, and technical documentation?
Download Flowserve product literature, brochures, and technical documentation through the Literature & Brochures section of Flowserve's website at Flowserve. That section is the company's own channel for product catalogs, brochures, and technical materials, and it sits alongside its Product Sales, Services & Repairs, and Specialists & Consultants contact options.
How to find what you need
- Go to Flowserve and look for Literature & Brochures in the site navigation or support menu.
- Search or filter by product family — the portfolio covers pumps, seals, valves, actuators and instrumentation, and energy recovery devices.
- If a document is not published, use the site's contact route to reach a representative or specialist, who can supply application-specific drawings, manuals, or data sheets.
Matching the document to your task
| Your situation | Best starting point |
|---|---|
| Comparing standard pump or valve models | Product portfolio pages, then brochures |
| Specifying for a critical or high-consequence process | Contact a specialist; request engineered documentation |
| Maintaining or repairing installed equipment | Services & Repairs, plus the relevant product manual |
| Early-stage project planning | Brochures and portfolio overviews first |
Practical next step
Write down your exact model, application, and fluid parameters before you search or make contact. A maintenance engineer specifying a replacement seal, for example, will get a faster, more accurate answer by quoting the existing part number and operating conditions than by browsing general brochures. If the literature library does not surface what you need, ask a Flowserve representative directly — for engineered and nuclear-grade equipment, documentation is often issued through that channel rather than posted publicly.
What industries and critical applications rely on Flowserve's flow control solutions?
Flowserve's flow control equipment serves industries where stopping or controlling flow is a safety, environmental or uptime concern rather than a routine maintenance item. The company's own framing is "critical industries" and "essential infrastructure," and its product line—pumps, valves, seals, actuators and instrumentation—is organized around fluid handling in demanding conditions.
Industries and applications named or strongly implied
- Oil and gas, including LNG. The Cryogenic Submerged Motor Pump – High Pressure series is built for LNG regasification, where cryogenic temperatures and continuous duty make pump reliability a cost and safety issue.
- Power generation. The acquisitions of Greenray and Allen Steam Turbines extend lifecycle support to aging gas and steam turbine fleets, a service aimed at plants extending the life of existing assets rather than building new ones.
- Nuclear. The Trillium Flow Technologies valves division acquisition is explicitly tied to nuclear valve solutions and OEM lifecycle services for "high-consequence" applications.
- Desalination. Energy recovery devices for SWRO (seawater reverse osmosis) target the largest operating cost in desalination—pumping energy.
- Chemical, pharmaceutical and food processing. The LMX Cartridge Lip Seal for top-entry mixers is aimed at applications where contamination risk and product purity matter, which points to hygienic and specialty chemical mixing.
- General heavy process and water infrastructure. The standard-to-engineered pump range and broad valve portfolio cover utilities, mining, pulp and paper, and other plants moving abrasive, corrosive or high-temperature fluids.
How to decide if it fits your case
The useful question is not "does Flowserve serve my industry" but "is my application critical enough to justify engineered equipment and lifecycle service." If a pump or valve failure means a shutdown, a safety event or a regulatory problem, the portfolio and service network are relevant. If you are specifying a commodity water or HVAC loop, standard commercial products from many suppliers will usually be cheaper and faster to replace.
A concrete next step: identify your fluid, temperature range, pressure class and whether the application is continuous or intermittent, then check the relevant portfolio page—pumps, valves, seals, or actuators and instrumentation—before contacting a representative. For lifecycle decisions on existing turbine or nuclear assets, the service and repair side of the business is the more relevant entry point than new product sales.
