The pump is made of stainless steel (motor) and cast iron
(hydraulics).
It is driven by a water pressure-tight, encapsulated motor. The
pump and the motor have a shared shaft. The fluid comes up
through the central suction opening and is pumped out
through the vertical discharge port.
The pumps are equipped with a single-stage VORTEX impeller.
It pumps solids of diameters up to 40 mm diameter (not fibrous
solids such as grass, leaves and rags).
The pump is either permanently installed and bolted to a fixed
pressure pipe (R 1 ½), or set up portably and connected to a
hose.
The motor chamber is sealed from the pump chamber using a
mechanical seal on the fluid side and a radial shaft seal on the
motor side. To ensure that the mechanical seal is always lubri-
cated and cooled, even when running dry, the mechanical
seal chamber is filled with oil.
The motors have thermal protection, switching off the motor
automatically on overheating, and switching it on again after
cooling down. The single-phase motor has a capacitor to gen-
erate the rotating magnetic field.

7. INSTALLATION AND ELECTRICAL CONNECTION

DANGER! Risk of fatal injury!
Improper installation and improper electrical connec-
tions can result in a risk of fatal injury.
•The installation and electrical connections should only
be done by properly skilled staff and in compliance
with applicable regulations!
•Follow all accident prevention regulations!
7.1 Installation
The pump was designed both for fixed and for mobile installa-
tion.
CAUTION! Danger of material damage!
Danger of damage due to improper handling.
Lift the pump using a chain or a rope attached to the
handle. Never lift using the power / float switch cable or
the pipe / hose connection.
The installation site or pit for the pump must be free of frost.
The pit must be cleared of coarse material such as rubble
before setting up and starting the pump.
For the installation dimensions see the drawing (Fig. 3), pit
dimension (Fig 2a).
The pressure pipe must have the same nominal width as the
pump (R 1½", can be enlarged).
It is essential that the pit allows the float switch to move freely
(Salmson FVO 204...F).
7.1.1 Stationary wet installation (Fig. 2a, 2b)
1 non-return valve
2 isolating valve
3 overflow alarm control
4 switchgear with connected float switch for pump operation
5 chain
6 Electrical connection motor cable
Fig. 2a:
Pump (Salmson FVO 204.F) with single-phase motor and
optional overflow alarm control.
Fig. 2b:
Pump with three-phase motor. Switchgear with connected
float switch for one pump operation and optional overflow
alarm control.
For stationary wet installation with a fixed pressure pipe, the
pump must be positioned and fastened to ensure the follow-
ing:
•The connection to the pressure pipe does not bear the weight
of the pump
•The load of the pressure pipe does not act on the connection
port
Provide a 4 mm diameter hole on the discharge pipe before
the check valve for a possible venting following a draining (Fig.
2a, 2b Pos. B)
