4.1.1 Hydraulics
Rotodynamic hydraulics with vortex impeller and hori-
zontal flange connection on the pressure side. The
screwed connection is integrated in the pressure port.
The hydraulics are not self-priming, in other words, the
fluid must flow in either automatically or with supply
pressure.
NOTICE
Combined connection for DN 50 and DN 65!
The Rocsan neo V06 is equipped with a DN 50/65
combined connection. The factory setting of the
connection is DN 65. To use the pump with a DN 50
connection, press the nuts in the flange inwards
onto the small hole circle. The flange can be reset to
DN 65 at any time!
4.1.2 Motor
The drive versions used are single-phase current and
three-phase current surface-cooled motors. The motor
is cooled by the fluid around it. The waste heat is trans-
ferred directly to the fluid via the motor housing. The
motor may emerge during operation.
With single-phase AC motors, the operating capacitor
is integrated in the motor. The connection cable is
available in the following versions:
▪ Single-phase version:
– With shockproof plug
– With a shockproof plug and fitted with a float switch
▪ Three-phase version:
– With bare cable end

Seal
Different designs are used for the seal to the fluid and
the motor compartment:
▪ Rocsan neo V05: A rotary shaft seal is used on the mo-
tor side, a mechanical seal is used on the fluid side.
▪ Rocsan neo V06: A mechanical seal is used on the mo-
tor side and the fluid side.
The sealing chamber between both seals is filled with
medical white oil.

Fitted accessories
Float switch
In the "A" version the pump is equipped with a float
switch. Depending on the fill level, it is possible to
switch the pump on and off automatically, by using the
float switch.
Plug
In the "P" and "A" version, a shockproof plug is at-
tached for single-phase AC motors and a CEE plug is
attached for three-phase motors The plug is designed
for use in commercially available shock-proof or CEE
sockets and is not overflow-proof.

Monitoring devices

Monitoring of motor winding
The thermal motor monitoring protects the motor
winding from overheating. Temperature limiting with
bimetallic strip is fitted as standard.
Thermal motor monitoring is self-switching for single-
phase current motors. I.e. if the motor is switched off
due to overheating and then cools down, it is automat-
ically switched on again.
For three-phase current motors, the thermal motor
monitoring must be connected in the switchgear or
plug.

Operating modes

Operating mode S1: Continuous duty
The pump can operate continuously at the rated load
without exceeding the permissible temperature.
Operating mode S2: Short-time duty
The maximum operating period is specified in minutes,
e.g. S2-15. The pause must last until the machine tem-
