Rotary Vaccume Pump

LVV Series Unique Features

• A unique design of lubricating system positively feeds minimum quantity of oil to important points. The oil from the exhaust is baffled, collected and returned back to oil chamber. This way not only the intervals between oil top up is prolonged, but also helps to keep the atmosphere in the premises free of oil smoke to some extent.
• Specifically heat treated fibre vanes are used in ACMEVAC pumps in place of steel vanes. The advantages are silent running, and negligible wear on stator, end covers and rotor slots
• ACMEVAC pumps are driven by V-belt covered with belt guard to give vibration free operation, and are fan cooled.
• The complete unit with motor and base plate is most compact for its capacity and due to its vibration free running is suitable for mounting inside the equipment.
• All the models in LVV series can be modified to suit specific application so that smallest possible pump with minimum power consumption can be offered to the user.

Applications

• Pharmaceutical, Chemical & Industrial Machines.
• Filling, Transferring, Holding.
• Conveying, packing, Filtering.

Technical Specifications

MB Series

These pumps are directly mounted on motor flange and hence very compact. The pumps are oil free and no external lubrication is required. They are light weight and easy potable. Applications include printing and packaging machines.

Specifications(MonoBlock)

Turbine Bowlers/Exhausters

PRINCIPLE OF OPERATION : These blowers consists of a dynamically balanced impeller which revolves in a stator-cum-compression chamber having very fine clearances between them. The impeller is fitted directly on to the motor shaft. Both the suction and pressure openings are located on the outer periphery of the stator to reduce impedence to the air flow thereby developing vacuum and pressure. Since the impeller rotates with no contact between itself and the casing, there is no wear and tear and requires no lubrication

APPLICATIONS : Manufacturing of textiles, Measuring, medical and laboratory equipment, Printing and paper handling, Vacuum packaging, Waste water treatment, Reprographics Industry, Aeration of fluids, Pneumatic Conveying, Plastic Industry, Industrial Ovens, Vacuum cleaners, Air Pollution monitoring equipment

FEATURES:

• No lubrication is required since there is no friction and hence the air is absolutely oil free.
• Practically nil maintenance cost.
• Extremely compact units and can be mounted inside the machines
• Silencer ensures low noise level.

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

• 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.
• 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.
• 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.
