By combining the use of radial diffusers, which allows a much shorter stage length, with a much larger shaft diameter, the rotor becomes much more stable, normally operating well below the first critical speed.

Cryodynamic Products

These cables are UL Underwriter’s Laboratory listed, and were developed specifically for use in cryogenic liquids. Cryogfnic the equipment produced utilizes submerged electric motors or generators, thus eliminating any rotating sealing system.

The inlet feet of the pump press down against the bottom plate, forcing the valve to open using the weight of the pump. The lifting cables used are an anti-twist, stainless steel cable, which can provide many years of use without replacement. The main in-tank power cables are Cryodynamics UL listed armored cables, and can be provided in all voltage ranges up to volts. It is fabricated with a suction nozzle, welded couplings for drain and liquid level indicationsupport brackets, a head plate with discharge nozzle, a conduit for electrical cables and a vent nozzle.

The valve is flanged to the lower end of the pump column and is closed by coil springs as well as by the hydrostatic pressure of the liquid in the tank. The entire pump and motor assembly are contained within a suction vessel built to the appropriate pressure vessel code for each application, making the installation safe, simple cryoegnic reliable.

Share this page with a friend! The submerged pump and motor unit is designed to fit into the smallest practical column diameter by using an axial diffuser design. These units are available for all applications of liquefied gas carriers and are used for main cargo ebata, stripping, spray and emergency retractable service. If you are looking for a cryogenic pump or turbine expander, you are in the right place.

It is fabricated with a suction nozzle, welded couplings for drain and liquid level indicationsupport brackets, a head plate with discharge nozzle, a conduit for electrical cables and a vent nozzle.

Each pump is fitted with an inducer which is an axial flow impeller located at the lowest possible level of the tank to improve the NPSHR Net Positive Suction Head Required ; allowing pup to lower tank liquid levels to extremely punp levels.

Who We Are

In-Tank Retractable ECR Type This unique design allows the pump to be installed inside a storage tank in a vertical pump column, with a suction foot valve located at the bottom. By combining the use of radial diffusers, which allows a much shorter stage length, with a much larger shaft diameter, the rotor becomes much more stable, normally operating well below the first critical speed. Cgyogenic pumps are of similar construction to the ECC type and are usually located within the refrigerated cargo tank of a marine gas carrier to transfer such fluids as LNG, LPG, Ethylene, etc.

This unique design allows the pump to be installed inside a storage tank in a vertical pump column with a suction foot valve located at the bottom.

Once the valve is closed, the column can be inerted with nitrogen gas to allow the safe removal of the pump even with liquid in the tank. In order to open the ebata, the inlet feet of the pump press down against the bottom plate during insertion, forcing it to open using just the weight of the pump. This eliminates the possibility of major tank leakage due to a pipe or pum; problem. Frequently used as a multistage design for vaporizer feed service, the ECC model is also widely used as a single stage transfer pupm.

The suction vessel functions ebarra the outer pump casing. As a result of the pump being installed through the top of the tank, all connections below the maximum liquid level of the tank can be eliminated.

Because the pump is installed through the top of the tank, all connections below the maximum liquid level of the tank can be eliminated. The valve is opened by lowering the pump into the valve. This new design has proven to be extremely reliable in send-out systems which require a large, multi-stage pump to perform on a continuous, 24 hour-per-day basis.

The suction vessel functions as the outer pump casing. To isolate the tank contents from the pump column, a suction valve is used, which incorporates a dual pressure sensitive seal.

The lifting cables used are an anti-twist, stainless steel cable, which can provide many years cryofenic use without replacement.

The power cables used in the retraction system are a high quality armored cable, made especially for Cryodynamics. Cryogenic Pumps Ebara Cryodynamics division of Ebara International Corporation is the recognized world leader in the engineering and production of specialized cryogenic liquefied gas pumps and turbine expanders. This new design has proven to be extremely reliable in send-out systems which require a large, multi-stage pump to perform on cruogenic continuous, 24 hour-per-day basis.

Electric power feed cables and deck penetration assemblies provided by Cryodynamics meet the requirements of all the major ship classification societies. The result is a compact, lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps. A single stage design is most often used, although multi-stage pumps can also be supplied if required.
