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.

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 operators to lower tank liquid levels to extremely low levels.

These units are available for all applications of liquefied gas carriers and are used for main cargo unloading, stripping, spray and emergency retractable service.

Frequently used as a multistage design for vaporizer feed service, the ECC model is also widely used as a single stage transfer pump. The valve is opened pmp lowering the pump into the valve. The suction vessel functions as the outer pump casing.

In-Tank (Retractable)

The result is a compact, lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps. The suction vessel functions as the outer pump casing. 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. For multi-stage pumps traditionally used for vaporizer send-out applications, Ebara has developed a radial, stiff shaft design, in order to provide a more compact, more reliable machine.

This design removes the possibility of major tank leakage due to a pipe or connection problem and also permits the storage vessel to be located below ground level.

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 valve, 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. To isolate the tank contents from the pump column, a suction valve is used, which incorporates a dual pressure sensitive seal.

In-Tank (Retractable) | Ebara International Cryodynamics Division

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. This new design has proven to be extremely reliable in send-out systems which require a large, ;ump pump to perform on a continuous, 24 hour-per-day basis. 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 and reliable.

The submerged pump and motor unit is designed to fit into the smallest practical column diameter by using an axial diffuser design. The power cables cryoggenic in the retraction system are a high quality armored cable, made especially for Cryodynamics. 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.

For multi-stage pumps traditionally used for vaporizer send-out applications, Cryodynamics has developed a radial, stiff shaft design in order to provide a more compact, more reliable machine. It can be closed at any time by simply hoisting the lifting eye located ebarx the top of the column headplate without disassembly of any other components.

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

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 inlet feet of the pump press down against the bottom plate, forcing the valve to open using the weight of the pump. These 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.

It also permits the storage vessel to be located below ground level or completely covered by mounding. All the equipment produced utilizes submerged electric motors or generators, thus eliminating any rotating sealing system.
