The hermetic pumps of the types БЭН, ЦНГ produced by LGM, JSC are operated reliably on submarines of projects 995 Borey and 885 Yasen.

The hermetic pumps have the simplicity of design, small dimensions, high reliability, low weight and increased vibration noise characteristics.

The pumps БЭН, ЦНГ form a monoblock in conjunction with an asynchronous electric motor..

Structural feature of pumps БЭН, ГЭН:

  - Absence of oil seals or other shaft seals, external leaks and related pollution of the environment;

  - The presence of the thin-walled sleeve, which protects the stator winding and rotor from contact with the fluid;

  - Cooling of the engine and lubrication of the sliding bearings is carried out by the pumped medium.

«LGM», JSC produces pumps of the type БЭН, ГЭН in a special version, which provides the required vibro-noise characteristics.

In recent years, the staff of "LGM", JSC has done a great job on import substitution of foreign sealed pumps for БЭН, ГЭН providing the domestic Navy with high-quality products.
