NHAT NAM ENGINEERING

Automatic visual inspection machine for ampoules, vials, cartridges and syringes.

The AV-E is the cutting-edge technology for the high-speed automatic inspection of pharmaceutical products such as vials, cartridges, ampoules¿ and syringes (mod. AV-EGS), ¿which represents the ideal solution to ensure that SVP products are essentially free of particulate and cosmetic defects.

Motor-Driven Metering Pump

Sigma/ 2 (Basic type)

Capacity range 50 – 420 l/h, 16 – 4 bar

Robust motor-driven metering pumps like the Sigma/ 2 Basic guarantee excellent process reliability with their patented multi-layer safety diaphragm. The diaphragm metering pump offers a number of power end versions, also suitable for use in areas at risk from explosion.

The robust pump for safe and reliable use.

The Sigma/ 2 diaphragm metering pump, together with pumps of type Sigma/ 1 and Sigma/ 3, represents an integrated product range. They cover the capacity range from 17 to 1,030 l/h, with a consistent operating concept, control concept and spare parts management. A wide range of power end versions is available, including some for use in ATEX areas.

Your benefits

Excellent process reliability:

  • In the event of an accident, the feed chemical does not escape to the outside nor into the pump’s power end, thanks to the patented multi-layer safety diaphragm with optical (optionally electric) signalling
  • Integrated relief valve protects the pump against overloading
  • Reliable operation by bleed option during the suction process

Flexible adaptation to the process:

  • The Sigma product range is available as standard in the ‘Physiologically safe in respect of wetted materials’ ‘F’ design.
  • Metering pumps with electro-polished stainless steel metering head enable them to be used in hygienically challenging applications
  • Wide range of power end versions, also for use in areas at risk from explosion, and different flange designs for the use of customised motors

Technical Data

  • Stroke length: 5 mm,
  • Stroke length adjustment range: 0 – 100%
  • Stroke length adjustment: manually using self-locking rotary dial in 1% increments (optionally with actuator or control drive)
  • With the right, constant conditions, correct installation and calibration, precision exceeds ±1 %, based on maximum stroke volume.
  • Wetted materials: PVDF, stainless steel 1.4571/1.4404, special materials on request
  • Patented multi-layer safety diaphragm with optical diaphragm rupture display (an option with diaphragm rupture warning system via a contact)
  • Integrated hydraulic relief and bleed valve
  • A wide range of power end versions is available: Three-phase standard AC motor, 1-phase AC motor, motors for use in areas at risk from explosion and different flange designs for use in customer-specific motors
  • For areas at risk from explosion II 2G Ex h IIC T3 Gb X or II 2G Ex h IIC T4 Gb X (optional)
  • IP 55 degree of protection
  • High-strength fibreglass-reinforced plastic housing with excellent chemical resistance
  • For reasons of safety, provide suitable overflow devices during installation for all mechanically deflected diaphragm metering pumps.

Motor data sheets can be requested for more information. Versions 265/460V – 60Hz, special motors or special motor flanges are available on request.

Motors less than 0.75 kW and motors designed for speed-controllable operation are not subject to the IE3 standard in compliance with the Ecodesign Directive 2009/125/EC.

Information for use in areas at risk from explosion

Only use pumps with the appropriate labelling in line with the ATEX Directive 2014/34/EC in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label correspond to or are superior to the conditions prevalent in the intended application.
