Electrical Installation; Liquid Temperature - SPX Johnson Pump CM90P7-1 Manual De Instrucciones

The pumps should not be used for sea-water
or other heavy soiled liquids. The pumps are
designed for continuous duty.

Liquid temperature

-40°C to +100°C (-40°F to + 212°F)
Ambient temperature in operation
-40°C to +70°C (-40°F to +158°F)
Not in operation
-40°C to +120°C (-40°F to +248°F)
System pressure:
-0,2 to 2,5 bar at 100°C (212°F)
The motors are designed for a service life of
5000 hours at nominal voltage and ambient
temperature of about 30°C (86°F).
Voltage range:
10 – 16V
20 – 32V
The motors withstands both raised voltage
and raised ambient temp within the ranges
but both will have a negative influence on
service life.
The pump should not be exposed to heat
radiation.
Max 60% glycol for a water-glycol mixture.

Electric installation in boat
The pump must be installed according
to ISO 10133 (Small craft – Electrical
system – Extra low voltage DC installation
for continuous current). Other electrical
devices, e.g. switch, circuit breaker, must be
installed between the pump and the positive
(+) lead on the battery (on the red wire).
Note: The fuse must be ignition protected.
All electrical connections must be placed
above highest water level.
All wire connections ought to be sealed with
a marine sealant, e.g. Vaseline, silicon rubber
or grease.
If the pump is connected with separate
earth lead, this should be yellow/green and
connected to the rear end bell of the motor,
Use a M3-screw.
See the wiring schema for correct
installation. Negative wire must be black.
Choose wire size in accordance with total
wire length (see table).
Note! Before installation with electrical
control systems, check that equipment to be
used is of sufficient rated capacity to accept
ampere draw of motor.
