Multi-stage ejectors with control valve, CMS-RSUV series

Multi-stage ejectors with control valve, CMS-R/S/U/V series

With its multi-stage ejectors, CMS series, COVAL proposes an adapted response to all applications which need high suction flow; like emptying of high volume tanks or handling of porous objects.

Thanks to their characteristics, the CMS multi-stage vacuum generators are perfectly appropriate to feed the vacuum grippers from distance.

Air amplifiers, M--C series

Air amplifiers, M–C series

The high suction flow vacuum generators are particularly adapted to applications involving porous and lightweight products. They offer a high suction flow, attaining an optimal vacuum level necessary for handling and transferring porous and lightweight objects. e.g.: powder, granules, carpet, foam etc.

Air amplifiers, M–C series

Applications

  • Gripping very porous and lightweight products: foam, carpet, cakes, leather
  • Transport of powdery materials: powder, granules
  • Transporting small, lightweight objects: paper clips, rice, coffee
  • Smoke evacuation, depressurizing chambers, etc.

Functioning principle

Thanks to the COANDA effect (wall effect), the motor flux draws in air at room temperature. This physical phenomenon greatly amplifies the flow which results in very high suction produced with low consumption.

Special

  • Stainless steel versions are available on request
  • The five products present the best amplification ratio (consumption/suction flow). Coval can study smaller amplification ratios (higher consumption) but higher maximum vacuum for transporting heavy objects.

Operating requirements

Compressed air filtration at 5 microns for the M6C model and 20 microns for the other models.

Specifications

– Compressed air: Dry non-lubricated, 1.5 to 6 bar
– Materials: Aluminium body
– Temperature: -20°C to +80°C / -4 to 176°F

Mini integrated vacuum pump with smart dialogue, LEM series

The COVAL innovation intelligent vacuum pump series originates from Twintech technology. Twintech is an ‘all in one’ concept which for the first time integrates all the necessary components at the heart of the vacuum pump. Thus the user eliminates the need to order and assemble the individual components such as electro valves, pilots, vacuum switches, pressure regulators, filters etc. The modular aspect of the intelligent vacuum pumps also allows the user to choose only the functions needed for the application.

Mini integrated vacuum pump with smart dialogue, LEM series

Presentation

Vacuum generation time & compressed-air consumption reduced by half.
The new COVAL LEM series vacuum module – TWINTECH technology – is connected to the network by a single M8 connector and has all integrated functions (electro-valves, pressure regulator, vacuum switch). Two times faster than traditional multi-stage technology, this allows the user to save 50% on compressed-air costs while reducing noise level by 30 dBA.

Presentation

Integration of a pressure regulation system at the heart of the device allows optimization of energy consumption at 4 bar in order to guarantee optimum performance. The LEM has other advantages, including modularity, auto-diagnostic capacity, and reduced size and weight. Focusing on constant innovation, COVAL’s vacuum managers help manufacturers to reduce energy consumption and noise level, as well as improving reliability and optimization of production equipment.

Branch-specific applications

Advantages

  • Direct control 24 V DC – 0.7W
    – M8 connectors, IP65 protection.
  • Simplified use
    – only one easy-to-install module;
    – instant pneumatic and vacuum connections;
    – plug and play.
  • LEM for each application
    – choice of vacuum level and suction flow rate
    – need only use necessary functions

Integrated mini vacuum pump with “ASC” (Air Saving Control), LEMAX series

Description

LEMAX is a new mini vacuum pump integrating technologies developed by COVAL for better productivity, efficiency and energy savings. It has a wide range of applications: packaging, robotics, plastics.

For the first time LEMAX integrates technology known as ASC (Air Saving Control). It generates energy savings of between 60% and 97%, depending on the products to be handled. The ASC activates to limit energy consumption at two levels:

  • Integrated vacuum regulation: reduction of energy consumption and noise level.
  • The ASC analyses the application and adapts itself to the airtight or porous pieces in order to optimize operation and energy consumption.

The advantages of LEMAX:

  • Unequalled compactness: fixed very close to the suction cups for short response times.
  • Smart communication: Easier experience at all stages: initial settings, production, maintenance.
  • Modularity

Vacuum pumps with integrated pressure regulator, GEM series

Presentation

A Coval innovation, the GEM series vacuum pumps integrate TWINTECH™ technology. GEM series pumps provide an “all-in-one” solution by integrating all the necessary functions, such as pressure regulator, electro pilots, valves, vacuum switch, silencers in a single compact module. The M12 connector radically simplifies installation and use.

The GEM series pumps are available in:

  • 2 vacuum levels: 60% and 90%
  • 5 nozzle diameters (1,2 ; 1,5 ; 2,0 ; 2,5 et 3,0 mm).

Options

The following specificities can be obtained on request:

  • Vacuum controlled by a NO solenoid pilot
    With a Normally Open solenoid pilot, the piece remains gripped even in the
    case of power failure.
    > safety measures for certain applications
  • Vacuum pump with automatic and timed blow-off
    > 1 single control signal.
  • Module with integrated vacuum gauge
    > visualisation of vacuum level.

Branch-specific applications

Specifications

Traditional single or multi-stage vacuum pump must be equipped with additional peripheral modules necessary for it to function: solenoid-pilots, valve and electronic circuit, supply pressure regulator; vacuum switch, which penalize the size, weight, connections and the overall cost of the vacuum system. The COVAL TWINTECH allows integration of all these functions into a single compact lightweight module. The installation is radically simplified: no more peripheral components to be selected, ordered or installed. An immediate connection to circuits is possible thanks to the M12 connection. Optimal exploitation and minimal consumption of compressed air.
