Application and selection overview
Industrial pumps, valves and fluid control products for process, water, energy and general industrial applications. Availability, configuration and delivery terms are confirmed according to the exact model and destination.
Key parameters to confirm
| Item | Information to provide |
|---|---|
| Medium | Name, concentration, density, viscosity, corrosiveness, toxicity and solids or gas content. |
| Operating conditions | Normal/minimum/maximum flow, suction/discharge pressure, temperature, NPSH and duty cycle. |
| Pump configuration | Pump type, impeller, seal, driver, motor, speed, mounting and standby philosophy. |
| Valve configuration | Valve type, size, pressure class, materials, trim, leakage class and flow direction. |
| Actuation and control | Manual, pneumatic, electric or hydraulic; supply, signal, fail position and feedback. |
RFQ checklist
- Provide P&ID, datasheet, complete model and nameplate.
- State all normal, design and limit conditions and changes in medium.
- Confirm flange/thread standard, pressure class, facing and face-to-face length.
- List materials, seal, actuator, positioner, limit switches and documents.
Common mistakes and risks
- Selecting a valve by size or pump by flow alone and ignoring system curve and differential pressure.
- Materials or seals incompatible with medium, cleaning chemical or temperature.
- Actuator thrust, fail position or available electric/air supply not confirmed.
Frequently asked questions
Can the old model be replaced directly?
Current process, connections, face-to-face dimensions, materials and controls must be checked because a changed system may make the old configuration unsuitable.
How can pump cavitation be avoided?
Review available NPSH, suction piping, level, temperature, viscosity, filters and operating point against manufacturer curves.
How is normally open or closed confirmed?
Define the safe position with power or air lost, actuator type, spring direction and process risk.
