Type NCTR is a volute casing pump according to API 610 with shaft seal, type VS4.
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 bearing of the pump and drive shaft takes place in plain bearings. The upper drive shaft is fixed by a grease-lubricated double-sided angular contact ball bearing.
This allows diving depths of up to 6 m.
