| FOR
THE RESISTANCE OF DRY RUNNING |
| 1. |
Valveless
construction |
|
A unique valveless
mechanism (internationally patented) helps retain water inside the
pump even without a check valve when the pump is turned off. This prevents
the pump from running dry and is another feature of our advanced valveless
technology.
|
| 2. |
Internationally
patented PPS bushing construction:
a). Radiation of heat for "high heat resistance"
b). Superior endurance in case of "dry running" |
| |
| When most pumps run dry, the
friction from the contact points will cause parts, such as the shaft
and the bushing, to break down from excess heat. The
original anit-heat construction of GV/GVF prevents the pump from
a heat deformation because the materials used for the contact point
works in lowering the temperature by radiating and insulating heat. |

| 3. |
Air-lock free construction |
|
When air enters the chamber during operation,
it will create an air pocket within a rear casing. However, the unique internal
design of our rear casing and the bushing will direct and release the air
as well as heat and slurry.

Cross Section |
| |
The original air-releasing construction
of the rear casing is useful for the prevention of the "air
lock" problem. |
| |
Carbon fiber, adopted for the reinforcement
of the rear casing, makes the pump strong against burst pressure. |

Internationally patented PPS bushing
construction |
| |
A selection of the bushings available
for the different types of chemicals and the presence of slurry.
(Common parts used to minimize stock requirements) |
| |
Available bushing materials are: carbon,
ceramic, and SiC. |
