Installation of the Cavitator
4.
Positioning
4.1
The Cavitator must be positioned so that the suction pipe is as short as
possible and there is a falling gradient towards the suction nozzle. Keep
the number of valves, bends and tee-fittings on the suction side at an
absolute minimum. There must be sufficient space around the Cavitator
for piping and access for maintenance.
Lining up the pipe systems
4.2
Carefully line up the pipes to the Cavitator suction and discharge
nozzles. Make sure that the pipe systems are adequately supported by
pipe supports so that the Cavitator body is not subject to strains and
weights from the pipe system.
Power
supply
4.3
The motor should be connected to the mains via a motor isolator in
accordance with local regulations. The motor should be connected in
accordance with the instructions inside the cover of the motor’s terminal
box.
The motor should be connected so that the direction of rotation of the
motor (and thus of the rotor) is counter-clockwise when viewed from the
front towards the suction nozzle of the Cavitator housing. (Figure 2)
Water supply for water-flushed shaft seal
4.4
A Cavitator with a water-flushed shaft seal has two hose connectors on
the seal flange. The hose connectors are 1/8” and fit an ø6 mm hose.
The necessary liquid rate is 15-30 l/h. Max. pressure is 7 bar (100 psig).
The hose connection in the seal flange should always be positioned
vertically with the fluid inlet underneath and the outlet on top.
Water consumption can be limited by installing a solenoid valve for the
flushing water on the supply side. The open/close function of the
solenoid valve can be controlled by the Cavitator´ s start/stop sequence.
Do not use flushing water connectors for steam or steam condensate. If
you want to use steam as the barrier medium a special aseptic piping is
required, see section 2.5.
Connecting steam or steam condensate for aseptic use
4.5
Shaft seals for aseptic use are supplied with ø6/ø4 PTFE pipes for
connections.
The connection for steam or steam condensate with static double seal in
the Cavitator body is supplied with fittings for 8 mm steel pipes.
Steam can be used at temperatures up to 150°C (302°F) and pressures
up to 5 bar (73 psig).
