Dry Running Measures:
¡¡
|
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.

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. |
