METRO G med

METRO G med material loaders have been specially developed to meet the needs of plastics processors in the medical and pharmaceutical industries and comply with all the strict hygiene requirements according to FDA 21 CFR regulations.

The top priority in the design of the material loaders was the high surface quality of the electro-polished stainless-steel body, ease of cleaning and process reliability. Therefore, strong stainless-steel material sieves, special filters with high quality seals are used which are suitable for clean room applications.

With the same quality features as the METRO G med hopper loaders, we offer numerous medical compliant accessories. For all our products from the medical line detailed documentation is supplied including factory certificates. In this way, you have all the necessary documents for a smooth audit for your entire system.

The plastic granulate is conveyed hygienically and without the possibility of contamination to its destination and fed to the machine as required. This eliminates material loss through incorrect handling and keeps the clean room clean and safe. The high-quality hygienic design and technical know-how ensure accurate and reliable operation.

Extensive family of material loaders

Suitable for any application.

The extensive family of material loaders allows for an optimal selection for any required material throughput. The units are available in 0.5, 1, 3, 6 and 30 liter volumes. In addition to these different unit sizes, different vacuum valve combinations enable an individual solution tailored to your needs.

Machine loader version

Perfect for hygroscopic materials, space constraints and low throughputs.

A machine loader version is available for conveying hygroscopic materials with small throughputs or when space is limited. The discharge module of the device has no discharge flap and is mounted directly on the feed throat of the processing machine.

The advantage is that you do not need a machine hopper and can work with a small supply of material. This is especially important for dried materials and the material dwell time is reduced to a minimum.

Electropolished stainless-steel

Contamination-free and easy to clean.

All material loaders bodies are designed to be as smooth as possible and are made of stainless-steel 1.4301(V2A) and then electropolished. This allows you contamination-free operation and easy cleaning due to the high surface quality.

Implosion vacuum valve

Ensures constant and stable material delivery and reduces maintenance costs.

The strong stainless-steel sieve is automatically cleaned by implosion after each conveying. This guarantees constant and reliable material conveying and reduces the maintenance costs for the unit.

Due to the high-quality seals used in the METRO G med, the material loader operates reliably, and the environment remains dust-free. The HEPA H13 implosion filter is supplied as a standard and enables use in the clean room.

METRO G med

Membrane implosion vacuum valve

Ideal for clean room conditions - guaranteed free of contamination.

The membrane implosion vacuum valve offers the same functions as the implosion vacuum valve but works without compressed air. Instead, the vacuum required for the switching process comes from the conveying system, which opens and closes the valve. This valve is therefore ideally suited for use in clean room applications.

METRO G med

Dedusting unit

Guarantees consistent material quality for critical applications.

The dedusting unit removes dust from high performance engineering plastics directly at the hopper loader, sending them to the central dust filter via the air flow. These expensive materials, now dust-free, can be processed without further delay. The HEPA H13 implosion filter installed as standard enables the machine to be used in clean rooms.

Hygienic design

For the highest requirements of the medical technology and pharmaceutical industry.

All surfaces in contact with the product are made of stainless steel or FDA-compliant plastics and thus the METRO G med hopper loader meets all requirements according to FDA 21 CFR.

  • Surfaces that come into contact with granulate have a maximum roughness of 0.8 μm Ra
  • Optimal cleanability: no dust corners, rounded transitions, completely removable discharge flap
  • Filtered ventilation air (FDA-compliant HEPA H13 air filter)
  • Detailed documentation of all components used in the construction of the material loader

METRO G med

Material inlet flap

Optimum conveying capacity and minimum wear.

The material loader inlet flaps make sure that multiple loaders can work together properly in a system. They limit the amount of vacuum required for a group of loaders connected to a coupling station. Thus, no check valves need to be installed in the material flow at the coupling station which would result in a reduction of conveying capacity and increased material abrasion.

An additional benefit of the plasma-nitrided inlet flap is that it acts as a deflector plate at the material inlet, protecting the body of the unit from wear.

Level sensor

Process reliability - no excess or shortage of granules.

A level sensor is installed as standard in all material loaders from 3 liters. The sensor ensures an efficient conveying process by conveying the optimum capacity with each conveying cycle.

Stainless-steel discharge flap

Optimal material flow and high abrasion resistance.

The large material outlet with a stainless-steel discharge flap is abrasion-resistant and meets all requirements for applications in the medical and pharmaceutical industries.

The angled design ensures complete emptying of the material loader after each conveying cycle.

METRO G med

Discharge flap with spring damper

Prevents material jamming and vacuum loss.

A discharge flap with spring damper prevents the flap from completely closing when it is not under vacuum. If there are granulate on the discharge flap at the beginning of pneumatic conveying, these are first sucked away. With increasing vacuum, the flap is then pressed against the spring and will close completely.

METRO G med

Discharge flap with counterweight

Visual status of the conveying cycle and easy service work.

The counterweight of the discharge flap is mounted on the outside so that the current status of the conveying cycle is visible at all times. Due to the easy accessibility, service work can be carried out uncomplicatedly and quickly.
