Reason of Adaption FLOOD BUSTER

Pump Rotation Speed

Problem of Existing Pump for Pump Gate
Starting water level100%Stopping water level

Small operable range

0%

Start and stop repeatedly“Cycle ON/OFF” increases a risk of
breakdown on electric board

In the worst case,the electrical board will burn.
Pump Gate Technology FLOOD BUSTER20

FLOOD BUSTER solve Problem

Pump Rotation Speed

Flood Buster solve the problem
Large operable range
100%

Starting water level can be
Set at any water level0%*No stopping water level is required

No need to start and stop repeatedly
Operation at any water level with full speed

Flood Buster has less load on the electricboard than the existing pump.
Pump Gate Technology FLOOD BUSTER

21

Another advantages of FLOOD BUSTER

1. Simple operation
Once you press the start button
you can leave it.

Usability

Flood Buster will stop automatically
30 minutes after water level indicator detectsthat the water level does not rise.

2. No inverter required
Durability

Since there is no inverter,
Flood Buster is hard to break
down and life cycle cost is cheap.

Another advantages of FLOOD BUSTER

3. Inundation risk reduction
Reliability

The water level can be kept low at all times
because there is no stopping water leveland standby operation is possible.
