Description/design

Submersible pump for vertical or horizontal installation in tanks to supply sprinkler systems.

Hydraulics

Multistage submersible-motor pump with semi-axial hydraulics. Housing parts made of EN‐GJL with 2K coating or G‑CuSn10, impellers made of G‑CuSn10. Guide housing with casing wear rings made of special bronze. Pressure connection as flange connection.

Motor

Three-phase motor with rewindable PVC‐insulated winding for direct and star-delta starting. Motor shroud made of A2/A4‐quality stainless steel or steel/G‐CuSn10. Pump connection up to 8" overall size as NEMA connection, as standardised connection from 10" and larger. Sealing of motor shaft by the use of a mechanical seal made of solid silicon carbide material.

Thrust bearing with rockers for absorption of high axial thrust. Negative axial thrust is absorbed by the counter-thrust bearing. Self-lubricating bearing. NU… series motors are filled with water‐glycol mixture as standard. Alternatively, they can be filled with drinking water (T version). U… series motors generally have to be filled with drinking water.

cooling

The motor is cooled by the pumped fluid. The motor must always be immersed when operated. Vertical installation is possible with or without cooling jacket. For horizontal installation, bearing brackets must be used for reinforcement of the unit. An anti-vortex plate or cooling jacket may be used to improve the inlet flow.

Pressure shroud

The pressure shroud is used for the direct installation of the unit in the pipe system. Standard models are without mounted non-return valves. The maximum inlet pressure is 10 bar or 5 bar on D 500 unit.

Configuration

It is important to observe VdS regulation VdS CEA 4001:2005‐09 when installing sprinkler pumps. Please contact VdS for details.
