M-3 Pump (only)
Cat No: 55PUMPM3C | $985.00 |
DESCRIPTION
The SUNMOTOR model M3 submersible pump is designed to operate on any
direct current power source from 12 to 17 volts. Capacities at various
voltages are shown in Figure 1.
WARNING: THIS PUMP MUST BE IN WATER TO
LUBRICATE AND COOL ITS CERAMIC BEARINGS. DO NOT OPERATE THE PUMP DRY.
INSTALLATION
1) The M3 pump is supplied with 7m of discharge hose. Connect the hose
to the pump outlet using the clamp provided.
2) Place the pump in the water and anchor it with the poly rope
3) The pump is supplied with 15m of submersible cable already attached.
Once the pump is submerged in water connect the cable to the d.c. power
source (red to +). Water flow should occur when power is available.
4) The quick connect cable junction included provides easy disconnect
between the pump and the power source.
OVERLOAD PROTECTION
The M3 has a built in overload protection device in the form of a
magnetic coupling between the pump impeller and the motor (See
attached
diagram). This system will decouple automatically if the motor
becomes
overloaded, either from too high a voltage (over 17v) or from an
obstruction in the pump impeller. If decoupling occurs the motor will
continue to operate but the pump impeller will stop until the problem
is corrected. To recouple the magnetic drive, simply disconnect the
power supply for a few seconds. No harm is caused by decoupling of the
magnetic drive.
MAINTENANCE
This pump is designed to provide many years of service with no
maintenance. Eventually the brushes in the motor will require
replacement. This is a simple procedure which can be done in the field.
Replacement brushes are available from your distributor or directly
from SUNMOTOR.
