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 ebata cables and a vent nozzle. 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. 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.

Special designs with built-in internal filtration are available to handle cargoes that are likely to suffer particulate contamination such as LPG.

The power cables used in the retraction system are a high quality cyogenic cable, made especially for Cryodynamics. The result is a compact, lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps.

If cryogenuc are looking for a cryogenic pump or turbine expander, you are in the right place. 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.

These cables are UL Underwriter’s Laboratory listed, and were developed specifically for use in cryogenic liquids.

Frequently used as a multistage design for vaporizer feed service, the ECC model is also widely used as a single stage transfer pump. The result pmup a compact, lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps.

The valve can also be closed by simply lifting up on the lifting eye located at the top of the column headplate, without dis-assembly of any other components.

The column then acts as a guide to seat the pump during installation and also as the discharge pipe from the pump to the top of the tank. Share this page with a friend!

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

Each pump is dbara with an inducer, which is an axial flow impeller located at the lowest possible level of the cyrogenic to improve the NPSHR Net Positive Suction Head Required and allow operators to lower tank liquid levels to extremely low levels.

For multi-stage pumps traditionally used for vaporizer send-out ebaga, Cryodynamics has developed a radial, stiff shaft design in order to provide a more cryogeinc, more reliable machine. The suction vessel functions as the outer pump casing.

The submerged pump and motor unit is designed to fit into the smallest practical column diameter by using an axial diffuser design. To isolate the tank contents from the pump column, a suction valve is used, which incorporates a dual pressure sensitive seal. 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. All the equipment produced utilizes submerged electric motors or generators, thus eliminating any rotating sealing system.

Crylgenic applicable codes allow the owner to minimize the land area needed to locate a liquefied gas storage tank due to the reduction of spillage potential. The suction 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.

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. The main in-tank power cables are Cryodynamics Crygenic listed armored cables, and can be provided in all voltage ranges up to volts. 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.

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.

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. Frequently used as a multistage design for vaporizer feed service, the ECC model is also widely used as a single stage transfer pump. 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.

To isolate the tank contents from the pump column, a suction valve is used, which incorporates a dual pressure sensitive seal. The valve is opened by lowering the pump into the valve. 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 submerged pump and motor unit is designed to fit into the smallest practical column diameter by using an axial diffuser design.

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 suction vessel functions as the outer pump casing. The column acts as a guide to seat the pump during installation and also performs as the discharge pipe from the pump to the top of the tank.

The lifting cables used are an anti-twist, stainless steel cable, which can provide many years of use without replacement. It also permits the storage vessel to be located below ground level or completely covered by mounding. The lifting cables used are an anti-twist, stainless steel cable, which can provide many years of use without replacement.

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.

These units are available for all applications of liquefied gas carriers and are used for main cargo unloading, stripping, spray and emergency retractable service. The power cables used in the retraction system are a high quality armored cable, made especially for EIC.
