The P-Series systems designs are available for both dense and dilute phase vacuum transfer for a wide variety of applications including capsule filler, tablet press, blender, and coater loading, feeder loading and refill, in line screening and sieving , and general ingredient conveying/transfer.
P-Series vacuum conveyors are designed with complete cleaning and ease of disassembly in mind. They are available as stand-alone units as well as integrated packages for the automated refill of K-Tron pharmaceutical design feeders. In addition, complete systems packages are also available for conveying pick up options from supersacks, drums, boxes, IBCs and FIBCs.
All conveying rates are based on a distance of 15 m [50 ft] and bulk density of 0.5 kg/dm3 [31 lb/ft3]. Rates vary with material characteristics, conveying distance and plant layout.
P-Series Vacuum Receivers as Refill Devices in Pharmaceutical ApplicationsThe method of refilling a Loss-in-Weight feeder in a continuous process can be almost as critical as the right choice of feeder technology. Since the objective is to refill as quickly as possible, pneumatic receivers that operate in either dilute phase or dense phase (in the case of some preblended formulations) mode are often used as refill devices, particularly for continuous operations.
In addition to the use of P-Series pneumatic systems for feeder refill, the systems are also used for a wide variety of material handling operations in the pharmaceutical industry. Full containment options are available complete with split butterfly valves on the receiver discharge. A variety of material pickup designs are provided, dependent upon the source of the material to be transferred, product and process safety concerns, and required parameters for cleaning cycles.
Premier and the K-Tron Process Group offer a number of specialty designs for pneumatic loaders and receivers, all dependent upon the requirements of the product and the process. Options are available for the conveying of potent or hazardous materials, including systems designs for the conveying of explosive materials. Modifications to the Premier P-Series design include the addition of retractable spray heads in the receiver body for cleaning and rinsing in place, as well as specialty swing out filter head designs to allow for easy access and removal of special filters.

Every pneumatic conveying solution for the pharmaceutical industry is custom developed according to the process and application, based upon years of experience with many challenging materials. Since the characteristics of bulk materials are often difficult to define, system solutions are usually tested in the lab.
Custom system design is available for a wide variety of process needs including pickup and delivery of potent compounds. These designs can include the integration of glove box or isolator technology at the powder pickup point, the addition of specialized docking stations with split butterfly valves for both product pickup and discharge from the vacuum receiver, the use of in-line sieving prior to delivery of the powder to the Loss-in-Weight feeder, and/or the use of specialized bag in/bag out secondary HEPA filtration prior to the vacuum source.
