The customer’s company is established in 2013 year, with the main business of selling hot water heating equipment. the following year they started selling equipment and assembling it.
So far they haven’t focused on just one product. Now slowly focusing on natural Gas equipment – Gas engines, Ammonia compressors and Geothermal pumps and equipment. Work directly with all factories on the territory of Macedonia. Have a team of 6 employees

We recommend you two submersible pump models 250QJR160-105 and 300QJR200-120. When the motor power is 75KW, the capacity is 42l/sec. And when the capacity is 60l/sec, the motor power should be 110KW.
The customer finally chose the 75kw pump
| Model | Capacity | Head | Power | Power supply | Speed | Pump Outer diameter | Pump material |
| 250QJR160-100 | 60l/sec | 90m | 75KW | 3phase/380V/50Hz | 2875rpm | 233mm | Stainless steel |
| 300QJR200-120 | 60l/sec | 110m | 110KW | 3phase/380V/50Hz | 2900rpm | 281mm | Stainless steel |
We supplied similar submersible sea water and deep well pumps to end user in Iceland and France. They are close to the submersible geothermal pumps in construction and use. These pumps have worked well for more than one year.
We suggest you transport this pump to your country by sea, and it will take about 40days to Skopje port.
