Pumps & compressors
Part of the Mechanical Engineering & Industrial Equipment sector
Pumps move liquids and compressors move and pressurise gases — core equipment for water, process, HVAC, oil and gas and manufacturing. This hub explains the main types and how to find and compare verified pump and compressor suppliers on Digibition.

Overview
Pumps and compressors are the machines that move fluids through a system. Pumps move liquids: centrifugal pumps for general flow, and positive-displacement pumps (gear, diaphragm, peristaltic, screw) for dosing, viscous media or high pressure. Compressors move and pressurise gases: reciprocating, screw, scroll and centrifugal types supply compressed air and process gases.
Selection is driven by the fluid, the flow and pressure (or head) required, and the duty — continuous or intermittent, clean or abrasive, hot or corrosive. Buyers include water and wastewater utilities, process plants, HVAC and building services, oil and gas operations, and manufacturers needing compressed air or fluid transfer. Equipment ranges from small units to large engineered packages.
On Digibition, pump and compressor manufacturers, package builders and authorised distributors publish verified profiles, so engineering and procurement buyers can discover and compare them by specialization and country.
What to check when sourcing
Start from the duty point. Define the fluid and its properties, the flow rate and the pressure or head you need, and the operating conditions (temperature, viscosity, solids, corrosiveness). Match the pump or compressor type and the materials of construction to that duty, and size it so it runs efficiently at your normal operating point rather than only at a peak rating.
Lifecycle cost usually outweighs purchase price: energy is often the largest cost over the life of a pump or compressor, so compare efficiency and part-load behaviour, and consider variable-speed drive where the duty varies. Check seals, materials and the controls or protection the application needs, and confirm the equipment carries the conformity marks your market requires for pressure equipment and machinery.
Support sustains reliability: ask about installation and commissioning, spare parts, seal and service availability and response time in your region. Use the directory to shortlist suppliers by specialization and country, then contact several and compare quotations, efficiency, delivery and support before you commit.
What to check when sourcing pumps and compressors
| Criterion | What to look for |
|---|---|
| Duty point | Flow and pressure/head matched to your real operating point |
| Fluid & conditions | Type suited to the fluid, temperature, solids and corrosiveness |
| Materials & seals | Construction materials and seals appropriate to the medium |
| Efficiency | Energy use and part-load behaviour, often the largest lifecycle cost |
| Controls | Variable-speed drive or protection where the duty varies |
| Support & compliance | Spare parts, service response and required conformity marks |
Frequently asked questions
- What is the difference between a pump and a compressor?
- A pump moves liquids, which are largely incompressible, while a compressor moves and raises the pressure of gases, which can be compressed. Both move fluids through a system, but the machine type, materials and controls differ with the medium and the duty.
- How are pumps categorised?
- Broadly into centrifugal pumps, which use a spinning impeller and suit general flow, and positive-displacement pumps (gear, diaphragm, peristaltic, screw), which move a fixed volume per cycle and suit dosing, viscous fluids or high pressure.
- How do I find pump and compressor suppliers?
- Use the Digibition directory to filter by this specialization and by country, then open each company profile to review its products, specializations and certifications. You can message suppliers directly, or add several to a quote list and request quotes from all of them at once.
- Why does efficiency matter so much here?
- Pumps and compressors often run for long hours, so energy is frequently the largest cost over their life — well above the purchase price. Comparing efficiency and part-load behaviour, and using variable-speed drive where the duty varies, can cut running cost significantly.
- What should I check before buying a pump or compressor?
- Define the duty point (flow, pressure, fluid and conditions) and size the machine to run efficiently there. Confirm materials, seals and controls suit the application, compare efficiency, and check the required conformity marks and local spare parts and service.
