The Power-driven Sucking Aerators, MB type, are designed for oxygen saturation of waste waters in the process of sewage biological treatment in ponds and other water-development works of enterprises of pulp-and-paper, chemical, petrochemical and other industries. The aerators are made of two versions, viz. MB 18.5-0,9 and MB 55-1,2, where figures 18,5 and 55 denote driving power in kW, while figures 0,9 and 1,2 - turbine-type agitator diameter in m. Making material is steel ÑòÇñï GOST380. For the adequate functioning of the aerator the structure depth should be from 2 to 5 meters.

The Power-driven Aerators with Stirring Facility, ÌÐÓ type (see foto), are designed to prevent the precipitation of suspended particles in waste waters of enterprises of pulp-and-paper, chemical, petrochemical and other industries. Driving power is 40 kW, material is steel ÑòÇñï, GOST 380. The structure depth is from 2 to 5 meters.

The Power-and-Air-driven Aerators, ÏM type, are intended for oxygen saturation and stirring of waste waters in the process of their biological treatment in aerotanks and other similar structures. The aerators are manufactured in three versions, viz. ÏÌ 18,5-1,1, ÏÌ 55-1,6, ÏÌ 75-1,5, where figures 18,5; 55; 75 denote driving power in kW, while figures 1,1; 1,6; 1,5 - agitator diameter in m. The structure depth is 5 m. Material is steel ÑòÇñï GOST 380.

The Power-driven Equipment with Stirring Facility, ÏÌ 25-0/0 type, is intended to stir formaldehyde or other resins with dynamic viscosity of not exceeding 0,5 Pa's, density of not exceeding 2000 kg/m³. Drive power 7,5 kW. Material is steel ÑòÇñï.

The Fermenter with Stirring Facility (see foto), volume capacity of 16 m³, is designed for stirring media consisting of heterogeneic components with dynamic viscosity of max. 0,65 Pa· s and density of max. 1350 kg/m³ and is used in such media as flour, water, chloramine, formalin, sunflower-seed oil, malt-residue filtrate, maize extract. These media are classified as corrosive, explosion- and fire-proof, Ó4 climatic version acc. to COST 15150-69. 

Operating pressure, 0,3 MPa (3 kgf/cm²). External pressure is vacuum with residual pressure of 300 mm Kg. Design intrinsic pressure, 0,365 MPa (3,65 kgf/cm²). Design ambient pressure, 0,4 MPa (4,0 kgf/cm²). Operating temperature condition, +30°C. 

Sterilization temperature condition, +140°C. Minimum permissible wall temperature, +30°C. Maximum permissible wall temperature, +150°C Material, steel 12X18H10T, GOST 5632-72. Steel 08X22H6T, GOST 5632-72 is admissible.
