Dependable design – unmatched performance

For decades, Svanehøj DW Cargo Pumps have been the backbone of marine cargo operations, renowned for their unwavering performance and efficiency. With more than 14.500 pumps delivered and more than 2.000 pumps currently in operation on gas carriers worldwide, the Svanehøj DW Cargo Pump is a testament to our engineering excellence. It is designed to handle a wide range of gas cargo, including LNG, LPG, ammonia, methanol, and ethane.

State of the art design

Our design is especially distinguished by having the electric motor of
the pump located outside the tank which eliminates excess heat and pressure.
This ensures that energy loss is avoided.

Pump solutions for all vessel types

At Svanehøj our product range in deepwell gas pumps ensures suitability for almost all needs and we tailor gas pump solutions for all vessel types. Our pumps can handle all types of gas cargo at all temperatures and gravities without any component changes, including LPG, ammonia, ethane, ethylene and LNG.

We offer tailored gas pump solutions for:

Fully pressurised tankers, cargo at ambient temperature, tank pressure up to 18 bar.
Semi-refrigerated tankers, cargo liquified by cooling/pressure process down to -104°C.
Fully refrigerated atmospheric tankers, cargo cooled to saturation temperature (typically -104°C). F
Fully refrigerated LNG carriers and LNG Bunker Barges at (temp).

Booster Pump for lighter cargos

Our NMB Booster Pumps act as boosters that increase discharging pressure when offloading lighter cargos. It is designed for liquid gas and is installed on fully refriger-ated carriers. The Booster Pump is also available in an in-line vertical version.

Capacity: 150 - 1000 m3/h

Benefits
The NMB series of pumps have stainless steel metallic parts in contact with the cargoes, self-actuating pressure setting of the shaft sealing system, easy accessible shaft bearings and sealings, and heavy duty flexible coupling connected to the e-motor.

Most important benefits:

A Svanehøj DW pump typically works 10 years inside a tank, before you need to pull it out for maintenance.
A thought-through design and the motor outside the tank ensures less vulnerability to contamination and clogging.
Significant energy efficiency and the reduced need for service and maintenance means low operation costs.
You don’t need to access the tank for service and maintenance. The DW pumps critical components are outside the tank.
LNG, LPG, Ammonia, Ethane, Ethylene and CO2 at all temperatures and gravities.
