Suction Vessel Mounted Pump - Type ECC

Enclosing the entire pump and motor unit within a suction vessel built to the appropriate pressure vessel code, makes the installation simple and safe. There is no need for alignment, couplings and auxiliary pipe work for seal purge or bearing cooling and lubrication. The suction vessel functions as the outer pump casing. It is fabricated with a suction nozzle, welded couplings (for drain and liquid level indication), support brackets, a head plate with discharge nozzle, a conduit for electrical cables, and a vent nozzle.

The result is a lightweight, uncomplicated installation having low noise levels and significant safety advantages over conventional pumps. The elimination of scheduled maintenance is also a benefit.

Frequently used as a multistage design for vaporizer feed service, the ECC model is also widely used as a single stage transfer pump. Flow capacities are available up to 5000 M3/HR and differential heads up to 2000 meters.

An attribute of all Cryodynamics pumps is the incorporation of the unique Thrust Equalizing Mechanism (TEM) which balances the axial forces on the antifriction bearings. This allows the bearings to operate at essentially zero load over the full flow range.
