|Type||Belt Drive Rotary Vane Pumps|
|Number Of Stages||Double Stage|
|Model Name/Number||PV1 / PV2 Water Cooled|
|Country of Origin||Made in India|
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.
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.

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.
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.
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.
