Closed-line transfer
Suitable granules, powders and lightweight materials are conveyed through enclosed piping.
APPLICATIONS · PNEUMATIC CONVEYING
Move bulk material through a closed pipeline.
Vacuum or pressure conveying systems are sized from material behaviour, required throughput, conveying distance, lift, bends, filtration and total pressure loss.
MATERIAL CONVEYINGMaterial + route + throughputOne system calculation
PROCESS OBJECTIVE
Transfer material cleanly and consistently.
Bulk density, particle size, moisture, fragility and flow behaviour change the required air velocity and pressure difference. Blower selection follows the complete line calculation.
Flexible pickup and discharge
Receivers, rotary valves and filters can be arranged around the plant layout and process sequence.
Controlled conveying velocity
Airflow is selected to move the material while limiting blockage, attrition and unnecessary energy use.
Central or dedicated systems
One blower may serve a dedicated machine or a controlled multi-point conveying network.
CONVEYING LINE
Every metre, bend and filter contributes to pressure loss.
Pipe diameter, horizontal and vertical distance, bends, filters, receivers and discharge equipment are included in the operating-point calculation.
SELECTING THE RIGHT SYSTEM
Select the blower from the material and route.
Four information groups define the conveying duty.
Talk to Our Technical TeamMaterial properties
Provide bulk density, particle size, moisture, temperature, fragility and flow behaviour.
Required throughput
Define mass flow, batch size, conveying time and the expected operating schedule.
Line geometry
Include pipe diameter, total length, vertical lift, bends and flexible sections.
Receiver and filtration
Filter area, cleaning method, rotary valve and discharge arrangement affect system resistance.

Published family ranges are indicative. Final selection must be checked at the actual operating pressure, gas or material load, temperature, duty cycle and installation conditions.
APPLICATION ENGINEERING
The vacuum source is one part of the complete system.
Reliable performance depends on the pump or blower, protection equipment, line arrangement, controls and the real process operating point.
Operating point
Capacity and pressure are checked together at the actual inlet conditions and duty cycle.
Share Operating DataProtection equipment
Filters, separators, condensers, receivers and valves are selected around moisture, particles, liquid carry-over and process risk.

Pipework, controls, isolation, accessibility and redundancy are included in the final system architecture.
