Type NCT
Volute casing submersible pump according to ISO 5199 with shaft seal
Q max: 1000 m³/h [4400 gpm]**
H max: 250 m [820 ft]**
operating pressure: 16 bar [232 psi/1.6 MPa]*
temperature: 200 °C [390°F]*
The type NCT is a volute casing submersible pump with shaft seal according to the principle of the two-pipe pump, i.e. separate shaft guide pipe and pressure pipe.
The hydraulic pump part is arranged in the container or in the pumped medium.
The connection is made by a multi-level shaft and pipe string. The bearings of the pump and drive shafts are in sleeve bearings. The upper drive shaft is fixed by a grease-lubricated double-sided angular ball bearing. This allows submersible lenght up to 6 m and this at a maximum operating temperature of 200°C [392°F].
In addition to the standard design, the NCT can also be supplied as a cantilever version without sleeve bearings, a heated design and an oil-lubricated design according to API 610 is possible. Furthermore, the NCT is also available as a variant for use in zone 0 in accordance with the Explosion Directive.
