Elements of a Vacuum Conveying System  

From pick-up spike to piping to receivers and vacuum pumps, PNEUCON offers a wide range of equipment for pneumatic conveying needs, whether for automated refill of feeding systems or as standalone conveying applications. The following list describes the varied elements available from PNEUCON for building a complete conveying system for loss-in-weight feeder refill (pictured in the diagram above).

Material Pick-up

From simple suction wands for free flowing materials to fully fluidized feed bins (1), silo pick-up pots (2) or bag dump stations (3) with prefeeders for powders, Premier offers a wide variety of equipment to ensure reliable material pick-up into the conveying air.

Conveying Line

Connect one or multiple material picks up stations to a vacuum receiver. To ensure blockage-free conveying, diverter valves (4) and line clearance valves (5) are available in addition to the piping.

Vacuum Receivers

Various models of central (7) and self-contained receivers are available to separate the material from the conveying air stream, alternating between suction and discharge modes of operation.

Sequence & Vent Valves

Sequence & vent valves (8) allow the air stream to bypass and vent the vacuum receiver during the discharge cycle.

Pump Packages

Vacuum pump packages include the pump — regenerative blower (9), sliding vane or rotary lobe blower (10) — to produce the air stream as well a bypass valve (11) to allow the pump to run while no receiver is conveying and a secondary filter (12) to protect the vacuum pump from entrance of foreign bodies.


HCU/HSU control and operator interface are available to control a single central or self-contained unit. To control the sequence of a multi-component system PLC controls (13) are available which are programmed to suit the client’s process. Siemens, Mitsubishi and Allen Bradley PLC controls are available.

Central Vacuum System

A central vacuum system has the ability to do the work of a dozen of smaller, individual cleaners. This central vacuum system aims to keep the entire industrial plan dust free and even getting rid of the dust and other dirt items.

The central vacuum system consists of a large media dust collector, like a cartridge or a bag house which has an inertial separator which can be used as a pre-sorter. The main advantage of this pre-sorter is that it helps to remove the large chips and then with the help of the media filtration, the fine particles can be removed.
