Stationary Concrete Pump BN 70D

Features

  • high pressure on concrete mix – 11 MPa
  • capacity – 70 cbm/h

Stationary high-pressure concrete pump is effectively used at construction sites with a large volume of concrete works: construction of high-rise buildings and facilities, monolithic construction.

The main drive system is a closed loop direct hydraulic drive system. High pressure enables to efficiently deliver concrete mix over long distances – horizontally to 600 m, vertically up to 130 m.

The basic systems of the stationary concrete pump BN-70D responsible for reliability and stability of the working cycle are equipped with imported components:

  • independent diesel engine D-260 (Minsk) or an engine DEUTZ (Germany) made to order;
  • the main hydraulic pump unit by Bosch Rexroth (Germany);
  • hydraulic accumulators (Czech Republic);
  • items of hydraulics and electrical equipment (Italy).

The loading hopper is equipped with a mixing device.
