3.3.2. Motor
The motor consists of an engine block and the engine
shaft with the impeller assembly. The circuit for power
supply is designed for the maximal mechanical perfor-
mance according to the characteristics or the nameplate
of the pump. The cable inlets as well as the circuit are
sealed resistant to jet water towards the pumped medi-
um. The shaft bearing is carried out by means of robust,
maintenance-free and permanently lubricated antifriction
bearings.

In the standard version of (1Ph) single phase motors,
the temperature sensors are connected internally in the
motor so that no special connection is necessary. After
cooling, the motor will restart automatically. The triggering
temperature of the sensors for standard version motors
is 130°C.
Checking direction of rotation
No check is required for single-handed motors, since
these always run in the correct direction.
Warning - rotating impeller!
Do not touch the rotating impeller or do not reach the
pump chamber through the pressure socket! Never
put your hands into the pump chamber or touch the
rotating parts in operating mode. Switch the machine
off and let the rotating parts come to gridlock before
carrying out maintenance work or repair work!
Furthermore it is possible to check the direction of rotation
with a 'motor and phase rotation indicator'. This measur-
ing device is held towards the engine block of the running
pump from externally and shows the direction of rotation
by means of LED.
Automatic float switch (version...A)
Version with automatic float switch HOMA Nivomatik, AS
floater, 20 meter connection cable, switchgear and manu-
al-0-auto switch. The single phase pumps are furthermore
provided with integrated condensers and connector. The
three phase pumps are provided with a CEE reversing
plug for rotational direction
Motor cooling
Sufficient motor cooling is also provided for in snore op-
eration due to the water jacket with pressure connection
on top.
3.3.4. Pump Casing
The pump casing is available with different pressure
discharges, depending on the version and engine varia-
tion. This creates an optimal connection to the various ty-
pes of pipework.
Discharge:
•
H 802 : G 1"
•
H 804 – H818 : G 1 ¼"
All pump casings (but not the type H816S) have a suction
sieve with spherical clearance of 0,1mm.
The type H816S has a sideways suction inlet G 1".
3.3.5. Impeller
The impeller are fixed on the engine shaft, which powers
it. The impellers are open multi-blade impeller.
Spherical clearance: up to 1,5mm
