Metering & Dosing Pump

Our metering/dosing pumps are high precision positive displacement pumps, according to the API 675 standard for controlled volume pumping. The discharge can be varied from zero to maximum capacity while pumps are running or at rest. Our pump design makes it an ideal flow control tool in chemical process for feeding chemicals with high degree of accuracy under any discharge pressure conditions. These are of robust design, unmatched quality and offer considerable saving due to small space requirement, low installation cost, minimum maintenance etc.

Typical Characteristics
Our dosing/metering pumps have a capacity output which is digital in nature, linear in proportion to the length of the stroke and is almost independent of discharge pressure.

Plunger Pumps

Plunger type liquid-ends are suitable for non-hazardous liquids. Because of their simple design, they are quite economical. They can be provided with flushing connection. In the case of molten liquids, steam jacketed heads can be provided. The jacket encloses the check valves and gland chamber. The valves are cartridge type and can be removed for servicing without dismantling the suction and discharge connections.

Diaphragm Pumps
Diaphragm type heads are suitable for service conditions involving hazardous, toxic, radio active or poisonous liquid, where product leakage is not at all permitted. The diaphragm is hydraulically actuated and has a long life, as it is always under hydraulic balance with the liquid being pumped on one side and actuating fluid on the opposite side. The function of the diaphragm is basically that of a partition. The diaphragm material is usually Teflon or synthetic rubber. The system is safe guarded by in built relief vacuum valve on the hydraulic side. For very severe duty condition or when handling slurry or hot liquids, double diaphragm and remote type heads can be provided.

Applications
Typical applications of our pumps are the accurate dosing and mixing of acids, alkalis, slurries, viscous liquids, etc. which may be pumped at elevated ambient or low temperature, twenty four hours a day. Our range covers everything from a single pump to a complete automated metering dosing system and comprising of plunger and diaphragm pumps with metering ranges from three to fifteen thousand LPH per pumps head. Pumps can be provided with up to twelve heads and all the necessary accessories can be provided with up to twelve heads and all the necessary accessories can also supplied.

Stroke Adjustment
The pump discharge is variable while pump is running or at rest from zero (0%) to full stroke by means of a precision machined crank equipped with a stroke length adjustment mechanism. The stroke of the pump can be controlled either – Manually (local) Automatic, electrically or pneumatically, (Remote)

Liquid End Material

Roots Blower (Water Cooled)
Item Code: VWR-VAR

“VINDI” make Water Cooled blowers are similar to air cooled type in construction and performance except in the change of cooling arrangement. In water cooled blowers the main casing & side plates have water jackets around them, where water is circulated, which dissipates the heat generated and keeps the internals cool. Water cooled blowers are recommended for applications where discharge pressures exceed 7000 mm WG, since it is essential to dissipate heat for efficient working and long life of the bearings and seals.
Our blowers have a unique design of single inlet & single outlet for cooling water and no cumbersome water pipe connections externally. Internal circulation of water to various areas is through inbuilt channels. This unique design makes the operations very simple, yet very effective. The cooling water inlet is at the bottom so that the water rises up against gravity, reaching all the corners before it comes out from the outlet. The flow rates of cooling water are low.

SPECIAL FEATURES
  • 100% oil free air delivery. 
  • Alloy steel hardened and ground timing gears.
  • Anti-friction bearings  
  • Rotary oil sealings
  • Rigid one piece CI casing and side plates  
  • Adjustable machine feet permit both horizontal & vertical flow of medium

Twin Lobe Compressors (Air Cooled)
Item Code: VR-VRK

Over a period of time we have developed a series twin lobe: positive displacement Roots blowers having unmatched quality & performance.  They have been specially designed for continuous applications, demanding constant flow at varying discharge pressures, such as in E.T.P., Pneumatic Conveying etc.

A rotary lobe blower, Roots Blower refers to a specific design of positive displacement compressor with two lobed impellers with a roughly figure "8" shape which are mechanically linked via gears such that they rotate in opposite directions. The figure "8" shape allows the impellers to be close to but never in contact with both each other and the pump walls at every position of their rotation. The close tolerances of the blower allow the impellers to move without a lubricant producing an oil free process flow.

These twin Lobe Pressure Compressors are Air Cooled Machines and are capable to develop pressure upto 1 kg./Cm2 & for vacuum duty up to 0.6 kg/cm2. The Compressors are being manufactured in 10 different models to cover the suction capacity ranging from 50 M3/hr to 10,000 M3/hr. As per required suction capacity and pressure requirement, suitable model of the Compressors can be offer.

These Compressors are designed in such a way that the same can have vertical or horizontal air flow.  Further, the Compressor with its standard accessories is being supplied as one compact unit which makes it very easy to install. It is also available as bare machine for replacement.

Two Stage Vacuum Pump

Two Stage Vacuum Pump
Item Code: RTS-Series

We offer highly efficient Two Stage water ring vacuum pumps. These pumps are better design than single stage vacuum pumps, having advantages of higher capacity at high vacuum and also require low quantity of water at low saves energy.

Two-stage vacuum pumps develop maximum vacuum of 720 mm of Hg, when sealing water temperature is 30ºC (755 mm of hg baro-metric pressure and suction temperature of 30ºC)and achieves vacuum up to 735 mm of Hg, when sealing water temperature is 15ºC to 18ºC.

Due to the latest technology and design, it so happens that a smaller model may require as compared to a single-stage vacuum pump.
 
In the conventional Single stage vacuum pump the performance after 70% vacuum falls down drastically, whereas the Two stage vacuum pump gives better performance after 70% vacuum. Normally the vacuum pump requires to run consistently between 70 to 90% vacuum.

In first stage, after creating vacuum up to 70% the compressed air / vapour mist with sealing media is led to the Second stage working chamber via crossover manifold. Second stage enhances the vacuum generated by the First stage.

This way, Two stage water ring vacuum pump gives nearly 50% more volumetric efficiency after 70% vacuum with the same electric motor rating. This results saving of nearly 50% power.

Air Ejector

Air Ejector

The maximum vacuum which can be created by Watering Vacuum Pump is limited to 93.3% i.e waterring vacuum pump create ultimate pressure of 50 mm Hg. This vacuum will be created with full closed suction. In other words, the capacity of the pump will be zero when it is operates at vacuum of 93.3%. In process, due to gas generation, the Vacuum Pump will never create 93.3% vacuum.

To achieve more vacuum, and to have suction capacity even at high vacuum, we recommend the installation of Air Ejector. Air Ejector when used in conjunction with Watering Vacuum Pump, creates maximum vacuum in the range of 97-98%. However, the affect of air ejector to increase the vacuum, can be ssen in the process where vacuum pump alone creates 92.5% vacuum. In such process, ejector should be used in conjuction with vacuum pump so as to achieve high vacuum in process

Installation of the Air Ejector does not call for any additional power connection. These are no parts subject to where and tear and hence, there is no mechanical maintenance for the Air Ejector.

The installation of the Air Ejector is as per the photograph. Initially, medium will be sucked from the system directly and, subsequently, i.e. after achieving 92.5% vacuum, medium will be sucked through the Air Ejector.
