In November 2016 the production and engineering company ENCE GmbH has successfully delivered a reworked pumping unit of the product ammonia pos. 109-J, by Shin Nippon Machinery, designed for feeding liquid ammonia (-33°C) to isothermal storage at PJSC DOROGOBUZH, part of PJSC AKRON holding.
The reworked pumping unit is a vertical 11-stage centrifugal pump (API610 class VS6) assembled with the electric motor, coupling and coupling case, meant for operating with cold liquid ammonia and unlike famous analogues its efficiency is 20% higher at the standard dimensions.
