Centrifugal with volute pump NCT

for crude oilfuelfor hydrocarbons

Description
The NCT is a volute casing submersible pump with shaft seal based on the two-pipe principle (separate shaft guide pipe and pressure pipe). The hydraulic pump section is located in the container or in the pumped medium and is connected via a multi-stage shaft and pipe string. Pump and drive shaft bearings use sleeve bearings; the upper drive shaft is fixed by a grease-lubricated double-sided angular ball bearing, enabling submersible lengths up to 6 m and operation up to 200 °C. Standard and optional designs are available to match process requirements.

Variants

• Standard design with sleeve bearings
• Cantilever version without sleeve bearings
• Heated version
• Oil-lubricated design according to API 610
• Variant certified for use in Zone 0 (explosion protection)

Applications

• Oil & gas
