The NDW pumps from DESMI are energy efficient and well proven for pumping every media from LPG, to LEG over a wide range of chemicals, through to CO2. The pump consists of three main components: base arrangement, pipe and pump cylinder. The cylinder is designed with a variable number of impellers and casings to meet the required head and capacity.

Advantages
The pipe stack consists of a number of intermediate pipes in which the cargo is transported to the outlet flange of the base arrangement. The intermediate shaft, which drives the impellers, is placed in the centre of the pipe stack. The shaft is supported by guide bearings for each 1.2 metres / 4 ft, which is also the length of the intermediate pipes in the pipe stack. The bearings are made of carbon and are lubricated by the cargo.
