How to Compare Pneumatic Conveying System Proposals Before Selecting a Supplier
When comparing a pneumatic conveying system proposal, price should not be the only factor. We should first compare whether each proposal is based on the same material requirements, conveying capacity, route, equipment scope, controls, installation interfaces, testing requirements and project responsibilities.
At Access Technology, our team helps manufacturers review pneumatic conveying requirements and system configurations so that different proposals can be compared on a more consistent basis before equipment selection.
Quick Checklist for Comparing Pneumatic Conveying System Proposals
| What to Compare | What to Look For |
|---|---|
| Material basis | Whether the same material characteristics were considered |
| Required capacity | Whether each proposal uses the same throughput requirement |
| Conveying route | Whether distance, vertical lift and bends are comparable |
| Conveying method | Vacuum, pressure or other suitable operating concept |
| Feeding equipment | How material enters the conveying line |
| Receiver and filtration | How material and conveying air are separated |
| Piping and valves | What is included and excluded |
| Controls | Sensors, sequence control and machine interfaces |
| Integration | Connection with existing production machinery |
| Installation scope | Mechanical, piping, electrical or control work included |
| Testing and adjustment | What is checked before technical handover |
| Technical support | What assistance is available after supply |
A lower pneumatic conveying system quotation may not result in a lower total project cost if important equipment, interfaces or site work are excluded.
Make Sure Every Proposal Uses the Same Design Basis
Before we compare prices, we first check whether every supplier is working from the same design information.
Two proposals cannot be compared fairly if one is based on a lower throughput, shorter route or different material assumptions. We recommend confirming the same:
Material being conveyed
Bulk density and particle size
Moisture and flow behaviour
Required conveying capacity
Batch size or operating pattern
Horizontal distance and vertical lift
Pick-up and discharge points
Upstream and downstream machinery
If one proposal is based on a shorter route, lower capacity or different material assumptions, comparing the final price alone can be misleading.
Material behaviour can influence equipment selection and overall system configuration. You can read our guide on how material characteristics affect pneumatic conveying system design for more detail.
If the required transfer rate still needs to be reviewed, our guide on how to calculate pneumatic conveying capacity explains the main factors to consider.
Compare the Conveying and Feeding Arrangement
The proposed conveying method should match the material, required capacity, route and production conditions.
Depending on the application, a supplier may propose vacuum conveying, pressure conveying, dilute-phase conveying or another suitable arrangement. The important question is not only what method is proposed, but why it was selected for your application.
A proposal is easier to evaluate when the conveying method is clearly connected to the actual application rather than presented only as a standard package.
We also recommend checking how material enters the conveying line. One proposal may include feeding equipment while another assumes material is already supplied under suitable conditions.
Compare:
Feeder type
Hopper or source-equipment interface
Feeding arrangement
Flow-control method
Connection to upstream machinery
Whether feeding equipment is included
A useful question is: Is the feeding equipment included, or is the system expected to connect to equipment supplied by another party?
For more detail, see how to choose a feeder for pneumatic conveying systems.
Compare the Main Equipment and Mechanical Scope
Two pneumatic conveying proposals may look similar while including very different equipment and mechanical scope.
We recommend comparing whether each proposal includes:
Receiver or separator
Filtration equipment
Discharge valves
Material discharge arrangement
Conveying pipeline
Bends and fittings
Valves
Flexible connections
Pipeline supports
Mechanical connections to existing machinery
The receiver, filtration and discharge arrangement should be reviewed together because they affect how material is separated, collected and transferred to the next production stage.
Our guide on how filtration affects pneumatic conveying system performance explains the filtration side in more detail.
Piping and mechanical scope can create important differences between two pneumatic conveying quotations. A proposal that includes conveying equipment but excludes piping or mechanical interfaces is not directly comparable with one that includes a wider installation scope.
If your project requires local site work, you can review our pneumatic conveying installation services in Malaysia.
Compare Controls and Automation Integration
Two systems with similar mechanical equipment can have very different integration scopes if one includes coordination with upstream and downstream machinery while the other operates independently.
We recommend checking whether the proposal includes:
Sensors
Valves and actuators
Motors
Control panel
Alarm functions
Operating sequence
Existing PLC interface
Communication with production machinery
The key point is to understand whether the proposed controls cover only standalone conveying or wider production-line integration.
If your project involves connection with existing controls, see what information is needed before an automation integration project.
Check What Is Included and Excluded
Before selecting a supplier, we recommend creating a side-by-side scope comparison rather than comparing only the total quotation value.
| Scope Item | Proposal A | Proposal B | Confirm Before Selection |
|---|---|---|---|
| Main conveying equipment | Included / Excluded | Included / Excluded | Model and duty |
| Feeding equipment | Included / Excluded | Included / Excluded | Interface responsibility |
| Receiver and filter | Included / Excluded | Included / Excluded | Capacity and arrangement |
| Piping and valves | Included / Excluded | Included / Excluded | Route and quantity |
| Control panel | Included / Excluded | Included / Excluded | Control functions |
| Automation integration | Included / Excluded | Included / Excluded | Signal and interface scope |
| Mechanical installation | Included / Excluded | Included / Excluded | Site responsibility |
| Testing and adjustment | Included / Excluded | Included / Excluded | Completion scope |
| Technical handover | Included / Excluded | Included / Excluded | Documentation and interface |
This makes it easier to identify whether an apparently lower quotation excludes equipment or work that will still need to be supplied elsewhere.
Compare Installation, Testing and Handover Responsibilities
We recommend clarifying who is responsible for piping, mechanical installation, electrical work, controls, equipment interfaces, testing, operating adjustment and technical handover.
At Access Technology, our team can support equipment supply, piping, mechanical installation, automation integration, testing, operating adjustment and technical handover, depending on the agreed project scope.
When comparing proposals, we recommend checking which party is responsible for each interface rather than assuming that every activity is automatically included.
You should also ask what will be checked before the system is handed over for production use. Testing, operating checks, adjustment and interface verification may differ between suppliers and should be stated clearly.
Do Not Compare Price Until the Scope Is Comparable
Price becomes meaningful only after the design basis and project scope are aligned.
Before comparing the final numbers, confirm that each quotation uses the same capacity basis, equipment scope, piping requirements, controls, installation responsibilities and testing or handover requirements.
If one quotation appears lower, first check whether important items have been excluded rather than assuming the system itself is less expensive. A higher initial value may reflect a wider equipment, integration or site-work scope.
The objective is not to choose the proposal with the longest scope, but to understand exactly what each supplier is offering and determine which proposal best matches your actual production requirements.
Questions to Ask Before Selecting a Pneumatic Conveying Supplier
Before making a final decision, we recommend asking each supplier the same core questions:
What material and capacity is the proposal based on?
Why was this conveying method selected?
What feeding, receiver and filtration equipment is included?
Is the conveying pipeline, including valves and supports, included?
What control equipment and automation interfaces are supplied?
Who is responsible for mechanical and electrical installation?
What testing and operating adjustment are included?
What technical handover is provided?
Which items are specifically excluded?
What project information still needs to be confirmed?
Using the same questions for every supplier makes genuine scope differences easier to identify.
