Supply Of Systems

Transformer Oil Filtration Machine

We are committed to providing a comprehensive solution for transformer oil filtration machine supply, onsite installation, commissioning, and after-sales service. The machine shall be supplied in accordance with customer specifications and can be further customized to meet the specific needs of the end user.
The plant shall be capable of treatment of new oil (as per IEC 296/IS:335) and reconditioning of used oil (as per IS:1865/IEC:422 for oil in-service) at rated capacity as follows:

The end results of the transformer oil filtration machine at its rated capacity are as follows:

Removal of moisture from 100 ppm to 3 ppm (max.) .
Removal of dissolved gas content from 10% by Vol. to 0.1% by vol.
Improvement of dielectric strength break down voltage from 20 KV to 70 KV (min).
Vacuum level of degassing chamber at rated flow and at final stage :- not more than 0.15 torr (0.2 m bar) max.
Filtering capacity: Max. particle < 0.5 micron in the filtered oil.
Processing temperature :- 40º C to 60ºC .

The unique features of the transformer oil filtration machine includes :

Capacity range from 500 LPH to 12000 LPH
Easy to clean preliminary filter inlet mesh used to catch hold coarse dirt
Standard efficiency of 0.5 micron/1 micron cartridge filter
Heat exchange through very low specific power electric heaters.
Degassing column with either single, two or three stage version.
Vacuum pump set in combination with rotary vane vacuum pump & roots pump to improve the vacuum pumping speed.
Compact, easy to operate the equipment

The various types of transformer oil filtration machines are as follows:

Single stage with evacuation & without evacuation system
Double stage with evacuation & without evacuation system.
Three stage with evacuation & without evacuation system.
Online & offline machine.

Oil Transfer Pump

Oil transfer pumps are mainly used in various industries for efficiently transferring oils and lubricants from one container to another.

Types of Oil Transfer Pumps: Oil transfer pumps come in several types, each designed for specific applications:

Centrifugal Pumps: Centrifugal pumps use centrifugal force to transfer fluids. They are efficient for transferring light oils and are commonly used in fueling stations and refineries.
Gear Pumps: Gear pumps utilize intermeshing gears to move oil from the inlet to the outlet. They are suitable for high-pressure applications and precise metering of oil.
Application: Transformer Oil , Hydraulic Oil , Turbine Oil
Capacity : 20 LPM to 200 LPM ( 600 LPH to 12000 LPH)
