operate.
|
|
As the water falls,
air disrupts the
circuit, and a timer
starts. The pump
continues to
operate.
|
|
Timer continues
pumping for about
1 minute. If water
again completes
the circuit, timer is
cancelled, until air
again interrupts the
circuit.
|
|
Or...
Timer continues
operation for about
1 minute. If air
continues to
interrupt the circuit,
the pump stops.
Until....
|
|
Water level rises to
complete the circuit,
and the pump
restarts.

- Multi - Directional
Discharge Connector:
Can be configured for
horizontal or vertical
discharge. Providing for a
more stable installation.
- Rubber Casing with Large
Rounded Cut-Waters:
Resists wear and
degradation of
performance due to
abrasive particles.
- Cable Boot: Prevents
kinking at cable entrance
by extending bending
radius.
- Anti - Wicking Block:
Prevents water incursion
due to capillary wicking,
should the power cable be
damaged or the end
submerged.
- Double Inside Mechanical
Seal with Silicon Carbide
Faces: Provides the
longest operational life of
any seal available.
- Oil Lifter: Provides
lubrication of the seal
faces down to 1/3 of
normal oil level and
extends seal life by ten
times - uses no additional
power!
- Miniature Thermal Motor
Protector: Protects
against overheating & run-
dry.

|
 |
|
|
|
|
|
"V" Ring Seal Protector: Protects mechanical seal from abrasive particles.
Urethane, Semi - Vortex impeller & Wear Plates: Resists wear by abrasive particles and does
not depend on close tolerances to maintain pump performance.
