Compact and Portable Fire Pump
for Hard to Access Areas
TOHATSU CORPORATION manufactures portable fire pumps, ideal for first response against building and brush fires. The pumps can be transported anywhere, making it possible to operate in both congested urban environments as well as difficult to access mountain terrains.
In addition to being compact and portable, the pump (Model VF53AS) is quiet and has low environmental impact. Also the fuel consumption is minimized by the electronically controlled fuel injection system, making this pump an economical option.
Since its start of production in 2006, several thousand VF53AS pumps were supplied to national fire agencies in many countries including Japan, China, Russia, Thailand, Singapore, Indonesia, Pakistan and Turkey.
Major Features and Advantages
I. Light Weight and Compact
The pump is made to achieve high output with compact and light weight design. VF53AS weighs 98kg with a four stroke, three cylinder engine and can be mounted on a truck for emergency deployment.
II. Low Environmental Impact
One of the main characteristics of this pump is cleaner emission. Compared to standard pumps, CO emission is lowered by 43%, and HC and NOx emissions are lowered by 90%. Also the noise level and vibration is low, making it easy to communicate verbally around the pump during operation.
III. Fuel Efficiency
Good fuel efficiency is important for keeping the running cost down. With VF53AS, the electronically controlled fuel injection system optimizes fuel supply to the engine depending on the engine speed, minimizing fuel consumption. The fuel injection system also ensures reliable engine ignition under various weather conditions even in the event of low battery power.
IV. Quick Start-up
The pump is able to start up quickly for quick attack operation. This is made possible by the rotary vane vacuum pump that is easy to operate. The rotary vane vacuum pump is automatically activated after the engine starts and turns off once priming is completed.
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.
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.

<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.
