DIAPHRAGM VACUUM PUMPS

DIAPHRAGM VACUUM PUMPS

Acmevac offer 100% oil-free Diaphragm Vacuum Pumps/Compressors. They can be used either as vacuum pumps or oil-free compressors and are designed for delivery of uncontaminated air, gases or va pours. They are suitable for producing oil-free compressed air or vacuum.

ADVANTAGES:
• Diaphragm type - hence no rubbing of parts and negligible wear & tear
• Practically maintenance free.
• No lubrication required, hence oil - free
• Low operational cost of equipment. This results from the modest cost for replacement of diaphragm and valves.

FEATURES:
• Heads are made of aluminum alloy castings
• Diaphragms are made of neoprene rubber or other elastomers depending on applications
• Specially designed motors in single - phase and three-phase constructions
• Pumps are mounted on rubber pads for silent, vibration-free running
• Due to compact design, these pumps are ideal for laboratories and original equipment manufacturers
• Compact, light-in-weight, hence portable

APPLICATIONS:
Pollution Monitoring Equipment, Chemical Analyzers, Laminating press, Material Handling Equipment, Labeling Machines, Plastic Welding Machines, Gas Welding Machines, Soldering iron, Agitation of Chemicals in Tanks, Aeration.

AIR SAMPLER

GENERAL PURPOSE AIR SAMPLER
Consists of a minipump driven by a d.c. Motor working on a 6 volt rechargeable battery. These work continuously for upto 10 hours between charging. If required, the air sampler can be used, while charging by 220 VAC mains supply. The screw arrangement allows variation of flowrates between 0.5 and 3.0 litres/ minutes. A flowmeter is mounted on the face of the box.

Pulsation dampers are internally fitted on the inlet and outlet gas circuit to smoothen the air flow. The pump unit is fitted into a M.S. Case of compact size. The sampler unit can be kept on a flat surface for stability at the breathing zone level of the worker to take TWA - TLV (8 hour) measurements. The air sampler is supplied with battery charger in a carrying case.

APPLICATION :

1.	Threshold limit valves - statutory requirements By sampling the breathing air, the short term exposure limit can be determined. Otherwise using the sampler for an 8 hour shift the TWA - TLV value can be ascertained for the contaminant.
2.	Dusts, Fumes, Mists For collection of toxic dusts e.g. arsenic, cadmium, beryllium, carbon black, cobalt, copper, lead, manganese, nickel rhodium, silver or tin, the use of a filter is the simplest. Many oxides or metal fumes, produced by casting, welding or burning, may be collected on a filter for analysis.
3.	Gases, Vapours and Solvents Using the sampler, a convenient collecting method is by adsorption tubes or detector tubes suitable to the gases & vapours to be analysed or for deadsorbtion for chromatograph analysis of the adsorbent. Also for adsorption into a liquid contained in a bubbler for chemical analysis.
