Hydraulics

Multistage submersible pump for vertical or horizontal construction with NEMA (6" and 8") or standard connection (10"). Radial or semi-axial impellers in sectional construction, integrated non-return valve. All parts that come in contact with the fluid are made of corrosion-free materials.

Motor

Rewindable three-phase motor for direct starting with PVC-isolated winding and a water-glycol filling. Hydraulic connection as NEMA (6" and 8") or standard connection (10"). Sealing of motor shaft with a mechanical seal made of carbon/ceramic material. Self-lubricating motor bearing. Thrust bearing with rockers for absorption of high axial thrust. Negative axial thrust is absorbed by the rotating seal bearing.

The motor is cooled by the pumped fluid. The motor must always be immersed when operated. The limit values for maximum fluid temperature and minimum flow velocity must be adhered to. Vertical installation is possible with or without cooling jacket. Horizontal installation must be performed in conjunction with a cooling jacket.

• Hydraulics and motor packaged separately, installation on-site
• Motor with 4.3 m connection cable
• Installation and operating instructions

• Motor and hydraulics pre-assembled
• Motor monitoring with Pt100 sensor
• Motors with star-delta activation
• Unit built in pressure shroud
