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

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. 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 suction vessel functions as the outer pump casing. 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.

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

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

A single stage design is most often used, although multi-stage pumps can also be supplied if required. 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 result is a compact, lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps. The result is a compact, lightweight, uncomplicated installation having low noise levels and cfyogenic safety advantages over conventional pumps.

The inlet feet of the pump press down against the bottom plate, forcing the valve to open using the weight of the pump. It also permits the storage vessel to be located below ground level or completely covered by mounding.

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. 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.

It can be closed at any time by simply hoisting the lifting eye located at the top of the column headplate without disassembly of any other components. 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 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.

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.

Electric power feed cables and deck penetration assemblies provided by Cryodynamics meet the requirements of all the major ship classification societies.

The power cables used in the retraction system are a high quality armored cable, made especially for EIC. The units are fixed to the bottom of the crgogenic 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.

Because the pump is 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. Sbara 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 pum level.

The power cables used in the retraction system are a high quality armored cable, made especially for Cryodynamics. Each pump is cryoyenic 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 and allow operators to lower tank liquid levels to extremely low levels.

The valve is flanged to the lower end of the pump column and is fbara by coil springs as well as by the hydrostatic pressure of the liquid in the tank. The entire pump and ebada assembly are contained within a suction vessel built to the appropriate pressure vessel code for each application, making the installation safe, simple and reliable. Inneholder ingen varer for totalt kr 0. 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.

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.

The suction vessel functions as the outer pump casing. 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.
