Cargo Deepwell pumps for LPG, LEG, Chemical and CO2 Tankers
DESMI’s new deepwell pumps, NDW, 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.
Materials
Stainless steel AISI 304 or similar for cargo temperatures down to -104° C. Stainless steel AISI 316L for special requirements.
Optionals
Drain pipe from pump head to pump cylinder for propylene oxide service
Intermediate support when pump exceeds 18 meters
Booster Pumps
DESMI also manufactures booster pumps to be placed on the deck and to support the DESWELL pump obtaining a higher total pressure of the cargo, if required by the gas terminal.
The booster pumps are single-stage centrifugal pumps available in various sizes according to requirements.
Technical Specifications:
- Capacity: 850 m³/h / 3742 gpm
- Pressure: up to 150 mLC / 0 - 459 ftLC
- Temperature: down to -165°C / -265°F
