Vacuum Pump

Product Details:

Generally, the main casing & almost all the components are fabricated from C.I. except the main shaft, which is of MS / EN-8. However, it is also offered in various combinations of resistant materials for specific applications. Details are supplied on demand. 

One of the main characteristics of Promivac water-ring pumps is that even under harsh conditions or under lack of proper supervision, these pumps continue to give satisfactory performance because none of its internal parts demand greasing or lubrication. These are least affected if a small quantity of vapour, dust, gas, or other such impurities enter its body through the suction nozzle. 

APPLICATIONS 

These are best suited for pharmaceutical, Food, Confectionery, Petro-chemicals, Textiles and plastic industries, Paper and Sugar mills, Cement, Metallurgical Laboratories and Furnaces, Refrigeration Plants, Distilleries, Pneumatic Conveying, Cigarette, Tiles and Ceramics industries etc. These pumps are approved for government, semi government and private industrial projects all over India.

Product Details:

These combine in them the two-fold features of suction and pressure and hence the same unit can be employed for either function. When used as vacuum pump, they can create vacuum up to 710 mm (28” Hg) provided the temperature of the sealant water is below 30 °C & barometric pressure at site is 30 Inches of Hg.

Product Details:

Promivac Reciprocating Piston Type Dry Vacuum Pumps are single stroke, air cooled, v-belt driven units, available in single & double stage configuration and can achieve Vacuum upto 29.6 Inches Hg (750 mm Hg). Fast evacuation, low oil consumption, low noise, faster heat dissipation, vibration free performance are some of the salient features of these pumps.

These pumps are quite reliable, maintenance free & versatile, proving a boon for applications wherein oil mist contamination is not at all acceptable.

The main components of the pump comprises of die casted aluminium alloy cylinder housing a reciprocating piston with rings, which is further connected to the drive shaft through a connecting rod. The cylinder head contains inlet and outlet valves. On the suction stroke of the piston, air is drawn into the cylinder from the system through the inlet manifold & inlet valves located in the cylinder head. On the upward stroke of the piston, the inlet valve closes and the discharge valve opens, permitting the air to be exhausted through the discharge manifold to atmosphere or a recovery system.

Efficient oil control is maintained with the help of direct connection between suction side of the system and the crankcase interior through a breather tube which creates pressure balance between both sides of the pistons and minimizes loss of lubricating oil through the piston rings. In addition, the crankcase vacuum tends to keep the oil dry by flashing off the condensable vapours that may have been sucked in from the system.

APPLICATIONS 

Menthol Oil Extraction, Vacuum Forming, Distillation, Filtration, Dehydration, Dairies, Paper Handling, Food & Plastic Processing, Sugar Industries, Centralised Vacuum Systems, Vacuum Impregnation, Holding & Conveying, Thermoforming and Centralised Hospital Systems etc. and many more.

Product Details:

These are available in single & double stage and are oil sealed, rotary vane type positive displacement pumps where, not only complete assembly is immersed in oil but shaft seal is also designed in such a way that it totally eliminates the possibility of suction of air through it.

These are designed to achieve maximum vacuum in a very short time and rise in temperature of the unit also remains under check, which in turn reduces the wear and tear of its components and makes it suitable for noiseless and trouble free performance for years and thus helps in reduction of repair bills.

BENEFICIARIES INCLUDE - Education, Research & Development and Industries like Pharmaceutical, Petrochemical, Cosmetic, Plastic, Oil Refinery, Offset Printing, Pneumatic Conveying & Holding, Packaging, Refrigeration, Automobiles, Chemical, Food & Fragrances  etc. and processes such as Annealing, Centralised Vacuum Systems, Composite Moulding, Thermoforming, Vacuum Filtration, Impregnation, Gas Charging, Freeze Drying, Bottle Filling, Food Processing, Vacuum Ovens, Autoclaves, Heat Treatment, Vacuum Brazing, Metalizing, Vacuum Packaging, Dehydration, Lamination, Chemical Reactors, Distillation, Evaporation, Solvent Recovery, Cryogenics, Analytical Instruments, Laboratory Systems, Vacuum Holding / Lifting, Polymer Processing, Essential Oil Processing, Crude Oil Refinery, Thin Film Coating, Electron Beam Welding, Jwellery Casting, Offset Printing, Space Simulation Chambers, CFL, Filament Tube, Flouroscent Tube, Neon Signs & Picture Tube Manufacturing. Vacuum Creation, Filling, Drying, Lifting, Forming, Filtration, Distillation, Annealing, Impregnation, Dehydration, Sublimation, Film Coating are few of the many more applications.

These pumps are very compact and are so simple in design that all minor repairs, in case of need, can be carried out easily without removing the main housing from its base plate and without disturbing the alignment. 

In industrial models, or in vacuum pumps of higher capacities which are operated continuously for very long spells of time the oil gets heated either on account of friction or on account of heavy intake of hot mixture of gas and vapours, the performance of the pump drops. In order to keep it cool, a jacket is constructed around three sides of the pump housing, in which water is made to circulate for keeping the temperature of vacuum pump under control and retaining the performance at its best. In this model an inbuilt device, known as Gas Ballast is provided, which effectively checks to a large extent condensation of the water vapours which otherwise would not only had contaminated the oil, but had also diminished the performance of the pump.

The same can also be used as backing pump with Roots Type Vacuum Booster, Diffusion & Turbomolecular Pumps for making High Vacuum Systems.
