New gear pumps of NMSHG120-10 type (the analog of the asphalt pump DS-125) were launched into production

New gear pumps of NMSHG120-10 type (the analog of the asphalt pump DS-125) were launched into production
The overall and mounting dimensions and technical characteristics of the new pump conform to asphalt pump DS-125.

New gear pump NMSHG 120-10 is designed to handle viscous and easily solidified liquids (paraffin, petroleum, fuel oil, bitumen, oil tar, emulsified bitumen, oils, oil products and so on), having a lubricating power and with kinematic viscosity of 0,75×10-4 up to 35,00×10-4 m2/s (10…470°E), at a temperature of up to 200°С (473 К).

The NMSHG 120-10 pump may be used in stationary installations, bitumen concrete plants, loading stations, mobile oil-delivery trucks and bitumen carriers in chemical processing, oil-producing and oil-refining industries where the electric pump DS-125 was previously used.

Advantages of the pump NMSHG 120-10:

  • simplicity of design maintains high reliability of the machine
  • maintenance-friendly and serviceable;
  • reversible sense of rotation (entry from either direction)
  • compact sizes allows usage within limited space
