Army base uses Tsurumi for military precision

A squad of 47 Tsurumi pumps are providing a complete wastewater solution at a military training base in Bulgaria. The pumps, which were installed in March 2011, are a mix of aerators, agitators, cutters, decanters and sewage pumps. Their reliability and simple maintenance ensures the remote 144 km2 base and 2,500 troops can focus on military training exercises and not worry about the wastewater situation on site.

Novo Selo Training Area (NSR) is a Bulgarian military training facility in Sliven, eastern Bulgaria. The base is used by Bulgarian and occasionally US troops for tank shooting, infantry skills and mountaineering.

The facility needed a new wastewater treatment system as part of an ongoing €50 million development. Tsurumi provided its pumping equipment and expertise to create a tailor-made and self-contained solution that would be effective and – more importantly – easy to maintain. The end result was put into place in March this year when 47 Tsurumi pumps and aerators were installed at the base.

Carsten Bode, product manager at Tsurumi Europe who worked closely on the NSR project, says: “Simple maintenance was the crucial factor in selecting the right pumping equipment. The base is very remote and we do not want to worry about the system breaking down and taking a long time to fix. Plus with so many troops on site – up to 2,500 – the treatment plant needs to be effective and not interrupt our day-to-day operations.”

The pumps are all positioned in and around two large cylindrical tanks measuring approximately 35 m long and 4 m wide that are buried underground. These plastic cylinders are the biological stage of the wastewater treatment process. They work as sequencing batch reactors and are connected to the base’s sanitation system through a network of pipes.

The 47 pumps at the base include 22 aerators installed as free-standing units within the two tanks. The remaining 25 comprise two cutter pumps, two agitators, three decanters, four channel impeller pumps and 14 vortex impeller pumps.

Remote reliability
With tank shooting and chemical warfare training among its list of activities, NSR had to be located in a very remote area. As previously mentioned, this meant the wastewater system had to be very reliable and simple to maintain. This is to avoid unnecessary (and lengthy) engineer call outs.

Tsurumi’s products are known for their strength and quality. With a reputation for hard work, some of its pumps can even be found working today after more than 25 years active service. Paramount to this longevity is Tsurumi’s patented oil lifter: a device positioned within the oil bath of every pump (from 0.4 kW to 200 kW) that significantly reduces day-to-day wear on the double-mechanical seal, which itself plays a major role in protecting the motor from internal water damage.

Tsurumi designs its products with easy maintenance in mind. Their simple construction means that most of the range can be dismantled with basic tools, such as a screwdriver or spanner, and simple maintenance can be carried out with only basic training.
