This eliminates the possibility of major tank leakage due to a pipe or connection problem. Each pump is fitted with an inducer, which is an axial flow impeller located at the lowest possible level crryogenic the tank to improve the NPSHR Net Positive Suction Head Required and allow operators to lower tank liquid levels to extremely low levels. These cables are UL Underwriter’s Laboratory listed, and were developed specifically for use in cryogenic liquids.

The main in-tank power cables are Cryodynamics UL listed armored cables, and can be provided in all voltage ranges up to volts. The submerged pump and motor unit is designed to fit into the smallest cryofenic column diameter by using an axial diffuser design.

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 ebafa, more reliable machine. 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 unique ebar 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, multi-stage pump to ebaea on a continuous, 24 hour-per-day basis. 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.

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

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. Cryognic the pump is installed through the top of the tank, all connections below the maximum liquid level of the tank can be eliminated.

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

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 units are fixed to the bottom of the tanks using a mounting arrangement designed to minimize stresses, and are connected directly to the discharge piping, which then travels out through the tops of the tanks.

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

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. Share this page with a friend! 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 lifting cables used are an anti-twist, stainless steel cable, which can provide many years of use without replacement. 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.

The submerged pump and motor unit is designed to fit into the smallest practical cryogehic 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.

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. The valve is opened by lowering the pump into the valve.

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 is a compact, lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps.

The applicable codes allow the owner to minimize the land area needed to locate cryoenic liquefied gas storage tank due to the reduction of spillage potential. The power cables used in the retraction system are a high quality armored cable, made especially for Cryodynamics.

It also permits the storage vessel to be located below ground level or completely covered by mounding. 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 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. To isolate the tank contents from the pump column, a suction valve is used, which incorporates a dual pressure sensitive pukp.

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.

These units are available for all applications of liquefied gas carriers and are used for main cargo unloading, stripping, spray and emergency retractable service. Inneholder ingen varer for totalt kr 0.

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. 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.
