Conceivable applications

The portable fire pump has been developed as a quick & first responder for building and brush fire.

The superior portability & transportability enables the pumps to be used in both congested urban environments as well as difficult to access mountain terrain.

Multiple pumps can be easily used in a relay system to provide water over long distance and duration.

The pump can also be mounted on a truck for emergency deployment ensuring maximum efficiency of transport with a full range of rescue equipment.

Competitive advantage

1. Light weight and compact:

Our engines and pumps are manufactured in house to strict standards maximizing compact and light weight product designs.

2. Quick priming:

Quick priming is provided by a simple operating Rotary Vane Vacuum Pump. The pump primes 3 meters in only 3 seconds. Priming speed is the most important factor and the key to a quick attack operation.

3. Low emission:

CO emission is lowered by 43%*. HC and NOx lowered by 90%*.

4. Low noise and less vibration:

Low noise (Reduced by 9dB*) and reduced vibration allows for easy verbal communication during operation.

5. Excellent fuel economy:

Electronically controlled fuel injection system facilitates optimum fuel supply depending on engine speed, minimizing fuel consumption.

6. Engine overheat protection sensor:

The engine overheat protection device is provided as a safeguard against cooling water loss and to protect the engine in the operation with the discharge valve closed. This device automatically shuts off the engine when the temperature reaches 80℃.

7. Electrically controlled fuel injection:

Electronically controlled fuel injection ensures reliable engine ignition under various weather conditions even in the event of low battery power.

8. Auto priming system:

Rotary vane vacuum pump is automatically activated after the engine starts and turns off once priming is completed.

9. Double swivel outlets swings through an arc of 90 degrees to enable the adjustment of discharge direction.  The discharge valve on a conventional firefighting pump is immobile and hard to adjust the direction.

Schematic illustration of the technology

①Putting out the fire（Suck water from fire hydrant and transfer water about 700m along）

②Relay pumping（Putting a number of reply pumps and transfer water to high altitude）

③Flooding situation（Sucking water up to 2cm depth with special suction tool）

④Simplified irrigation system（Utilize the discharge pressure of the pump）

<Example of use of Tohatsu pumps>

UNIDO launched the project titled “Integrated stabilization, economic recovery and reconstruction support for displaced persons and returnees in Iraq” in April 2016. In collaboration with UNIDO, Tohatsu delivered the training on principles of small motor engines and how they are able to drive water pumps for two of the mechanic instructors and one technical adviser from the Swedish Academy for Training (SAT) in Erbil, Kurdistan Region of Iraq. Training was conducted on two sizes of Tohatsu pumps : a large VC82ASE export model with a two-stroke water cooled spark ignition engine along with a smaller V20ES two-stroke air cooled spark ignition engine. Both were stripped down to sub-level components and rebuilt and tested for working operation. After three full days of hand-on training and an afternoon of audio-visual theory instructions on Tohatsu models and functionality of water pumps/engines, a certificate of attendance was presented to all three trainees.
