These Vacuum pumps that are vacuum/ compressor pumps are of positive displacement type and consists of an impeller, which is mounted eccentrically in a cylindrical casing. Generally, simple water is used as the sealing liquid.

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

These vacuum pumps combine in them the two-fold features of suction and pressures and hence the same unit can be employed for either function. When used as a Vacuum Pump, they can create Vacuum upto 710 mm Hg. (28” Hg) provided the temperature of the sealant water is below 30°C & barometric pressures at site is 30 inches of Hg. When used as a compressor, they can deliver pure and oil free compressed air with maximum pressures up to 1.5kg/cm .

These are 100 % Leak Proof & Seal Less Magnetic Drive Chemical Process Pumps are based upon the latest technology, which is quite different from the one employed by conventional Chemical Process & Centrifugal pumps.

The most revolutionary characteristic of this pump is that neither the pulley is employed nor the coupling is used to rotate the improper of the pump. Which moves the liquid or the chemical. Motor is fitted in a separate casing and so is the pump. When the motor starts rotating, the pump automatically starts working in its own casing and starts pushing up the liquid.

• Minimize Personal Exposure to Hazardous Material

These are virtually maintenance free as these perform neatly without causing any friction or vibration. The moving parts neither touch each other nor have any contact with its stationery body, therefore require no lubrication at all and generate oil free Vacuum & Pressure. Their compact design & rugged construction supplemented with trouble free performance have made them cost effective as well.

Based on revolutionary, Innovation, Promivac Blowers are worthy substitutes of their closest rivals, the conventional oily and bulky Roots Air Blowers, for application where large and forceful suction and pressure capabilities are required such as in Vacuum conveying, Vacuum Cleaning, Material Handling, Food, Drug and Chemical Equipment, Fume Extraction, Soil Vapor and Smoke Evacuation, Plastic Forming. Medical Equipment, Bag Making, Packing Industries and so on.
These are not only comparatively lighter, cheaper, neater & quieter, but also happen to be maintenance and oil free alternative of the above named monster.

These are specially designed to ensure high quality of Impregnation at a much faster rate than that of the conventional type. Here, both the chambers can perform turn by turn, the duties of an impregnating chamber and that of a storage tank, whereby we not only get increase in capacity, but can also save on time as well. Thus in a way, this fulfills the duty of a bigger plant.

The tanks are fabricated from M.S. sheets of appropriate thickness and are fitted with leak proof lids with handles. Two viewing ports are provided on each tank for observing the process under light. Each tank is provided with a vacuum gauge, vacuum line, valve and air leak valve. At the bottom, impregnent admittance valve, drain valve and inter transfer valves are provided. The unit is mounted on angled iron stand for facilitating smooth and easy operation. Promivac double stage high vacuum pump driven by most reliable electric motor is supplied with each unit to create vacuum of the required degree.
