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.

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.

These pumps combine in them double features of suction & pressure and hence the same unit can be employed for either purpose. These have low oil consumption and are compact in design, noiseless & care free in operation and easily maintainable. The main assembly consists of a stator with a rotor mounted eccentrically in it. The rotor is provided with eight vanes, which are free to slide and move in & out of the slots, by centrifugal action. When in 'out' position these press against the inner walls of stator. When the rotor rotates, these vanes sweep the air eight times in a single revolution creating vacuum & pressure simultaneously. The design provides for self-lubrication of all the important points and the oil thus used does not contaminate the air, but is baffled from the exhaust, gets collected and returns to the oil chamber. Each and every unit is fully engineered with all its components immaculately finished and matched. The walls of all components are suitably strengthened so as to render sufficiently long life even while working under adverse conditions. All the components are machined, drilled and finished with jigs and fixtures and are hence easily replaceable. All these distinguished features therefore, add up to make these pumps an indisputable choice of all reputed companies and concerns.

These are 100% Oil Free, wherein not even a single drop of oil is used. These are a boon for Vacuum & Pressure Applications, where even slightest Environmental Contamination through oil mist is forbidden. Chemical Analysers, Pollution Control Equipments, Gas Monitoring, Nitrogen Generating Sets, Ozone Generators, Operating Clinical, Medical & Scientific Laboratory Equipments, Suction of Desoldering Waste, Filtration, Dentistries & Spray Painting.

Vacuum Metalizing Plants, have earned enviable reputation in a short time. These are manufactured with high quality material & precision workmanship, in a well equipped workshop under the direct supervision of experienced and qualified engineers.

There should not be any cause of worry, if the already employed Vacuum Pump is found not competent enough to meet the requirements of the specific complex application, in terms of Pumping Speed, Ultimate Vacuum or Overall Performance, because now 'PROMIVAC' Mechanical Vacuum Boosters are there at your beck & call, just ready to come to your rescue by immediately taking over this challenging task. Vacuum Boosters also known as Mechanical Boosters are dry pumps that meet most of the ideal Vacuum Pumping requirements. These are Positive Displacement type & are designed to handle large quantity of gases under low working pressures and are manufactured keeping close tolerances and ensuring complete air tightness.

Capacity : 100 m3 /Hr

A maintenance free, noise less blower because of no friction, no vibration & needs no lubrication at all. Consequently, completely wear & tear free. Based on revolutionary innovation, It is comparatively quieter, lighter and practically maintenance & oil free substitute of the noisy, bulky, oily and monstrous type of conventional air blowers, for the applications where large and forceful suction and pressure capabilities are required in agitation of chemicals.

Roots air blower twin lobe compressor is a positive displacement, constant volume machine to operate against varying pressures. With each revolution, the compressor delivers a metered amount of air measured at inlet conditions. Operating at a constant speed against almost constant pressure, it delivers constant stream of pressurized air flow. No contamination, no oil, no spring, no valves or vanes, no internal contact of any parts and hence is free of wear and tear.

These double chambered continuous Impregnation plant are specially designed to ensure high quality of Impregnation at a much faster rate than that of the conventional type. Here, both the chambers, in turns can be used as Impregnation as well as storage tanks where by, we not only get increase in capacity, but also save on time as well. Thus in a way this full-fills the duty of a bigger plant. The tanks are fabricated from M.S. plate 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.

Application : Commercial

The Sludge Suction Pump is available in various capacities and different models suiting for permanent fixation, supporting on a trolley and for mounting right on the chassis of the mobile tanker into which the sludge sewage is required to be sucked. In the latter option the pump can be made to run with the same engine, which is moving the tanker.A Four Way Valve is an optional accessory, which when employed, would make Suction quite smoother, Forced Disposal of the sludge quicker and both possible through the same Single Port of the tank.

Specially designed and fabricated to satisfy the ever increasing demand of municipalities and contractors for their employing this pump for cleaning the chocked sewage lines, emptying septic tanks and disposal of the accumulated sludge from the manholes and mobile toilet units by suction.

PROMIVAC Rotary Vane Vacuum Pumps are single stage, oil lubricated vane type with inbuilt oil-circulation and anti-suckback system.The main assembly of the pump comprises of a dynamically balanced rotor with three or four specially treated fiber vanes which is mounted in a stator. When the rotor is made to rotate with the aid of the connected electric motor, these vanes move in & out of the slots by centrifugal force & slide against the walls of the stator pushing thereby the trapped air out of the stator & prompting the atmospheric air to gush in spontaneously to fill in the empty space.
