Characteristics and purpose of fire pumps

Water is almost always used to extinguish a fire in domestic and industrial conditions. But conventional pumps are unable to supply it in the required amount. Therefore, fire-fighting motor pumps come to the rescue.

Despite such a romantic name, this product has a number of advantages:

• high structural reliability;

• low fuel consumption;

• cooling the engine with air flows;

• excellent resistance to pollution;

• easy start;

• high pumping capacity.

The attractive technical characteristics are due in large part to the quality manual piston pump. It is capable of pumping water from a depth of 7.5 meters.

The shaft is sealed axially and at the end in such a way as to minimize the need for maintenance. All pump connections are made in accordance with Russian GOST. The engine is started using non-contact transistor ignition; pressure lubrication is provided.

At the request of the customer, this motor pump can be equipped with:

• electric starter;

• mesh that prevents the absorption of dirt;

• non-standard adapters;

• spotlight.

A single-stage centrifugal pump with a suction height of 3 meters can deliver 10 liters of water in 1 second.

The dry weight of the device is 58 kg. After refueling, it grows to 66 kg.

The total power of the engine, which receives fuel from a tank with a capacity of 8.5 liters, reaches 18 liters. with.

Its main purpose is the same as that of stationary options. But an important feature is the ability to move to another place (with a connection to a fire reservoir). Such equipment is used not only for extinguishing fires, but also for draining flooded buildings, caves, lowlands.

When choosing a portable motor pump, you need to pay attention to the following factors:

• overall pump performance;

• engine power;

• the size of the device;

• the amount of fuel consumed.

For both stationary and portable motor pumps, the run-in mode is of great importance. The essence of this procedure is to run in to each other the outer surfaces of the parts. All burrs and small roughness are removed at the same time.

This type of fire pump is equipped with a two-stroke engine with two cylinders. The total capacity of the plant reaches 40.8 liters. sec., which is not surprising, since the capacity of the combustion chamber is 617 cubic meters. see Such a powerful motor is water-cooled. To work for 1 hour, he needs 16 liters of AI-92 gasoline.

The energy generated by the engine is transferred to a single-stage turbine-type pump. Its head varies from 40 to 100 meters (from 4 to 10 kgf / cm2) with a step of 20 meters (2 kgf / cm2). Liquid flows in through a hole with a diameter of 10 cm. The outlet is noticeably narrower - only 6.6 cm. Self-priming of water is possible from a depth of up to 9 meters.

The pump body of this motor pump is made of a corrosion-resistant aluminum-based alloy. This solution made it possible to reduce weight, while at the same time extending the period of operation. Unlike steel counterparts, the unit can even pump seawater.

‌According to the manufacturer, the water used to cool the engine cools down, then returns, and therefore does not harm the environment. The engineers managed to solve the problem of starting the pump in all weather conditions.

If suddenly the power plant overheats for any reason (the temperature has reached 89 degrees or more), then at the command of a special sensor it stops... The capacity of the fuel tank ensures maximum pump operation for 1 hour. The branch pipe through which the water is discharged outside can rotate at an angle of 90 degrees.

This Russian motor-pump can supply 36 thousand liters of water to the direction of the fire in one hour. It is equipped with a reliable pump powered by a 5.5 liter engine. with.

The greatest liquid suction depth is 8 meters, with a head of 26 meters (2.6 kgf / cm²). The pump allows water with contaminants up to 1.5 cm in diameter to pass through. The total dry weight of the Zubr ZBMP-600 is 24.1 kg.

Such a device has increased power. The pump is capable of pumping 20 liters of water in 1 second. The nominal head is 80 meters (8 kgf / cm²), at maximum engine load it doubles. Liquid suction is possible from a depth of 8 meters. A motor from a VAZ 2103 engine with a total capacity of 71.4 liters is used as a drive. with.

Judging by the characteristics, there are few at least close analogs. "Aquarius" has been produced since 2004. Motor pumps of this model are subdivided according to the type of transportation into portable (equipped with skids) and transportable (with a cart) types.

Connection of pressure hoses of 0.2x7 cm format is allowed.

The suction shaft has a size of 0.1x10 cm. If we add adapters to the motor pump, it is possible to work with six shafts at once, located within 2 km from the water source. The device is equipped with a single-stage pump, which contains an impeller with a diameter of 25 cm.

It is recommended to use "Aquarius MP-16/80" at the following facilities:

• on the territory of country holiday homes;

• in suburban settlements;

• at logging;

• in other remote and inaccessible places for fire protection.

A small-sized mobile motor pump "Mini-Stryker" is quite suitable for solving this problem. Despite its small size, it provides a high head. This attractive combination of properties allows the unit to be quickly transported to the scene and effectively suppress even strong flames.

Systems commonly used for fire extinguishing have an unjustified tilt to one side or the other. Due to the low consumption of fuel, it is possible to extinguish fires lasting more than 1 hour continuously.

The developers took care of preventing engine deformation due to a drop in the oil level in the crankcase. There is a special sensor that detects its excessive loss... This solution increases the pump usage time by 15% compared to analogues. The pump parts themselves are made of aluminum alloy, additionally anodized. The pump system can be used not only for fire protection, but also for purely domestic purposes.

The Geyser MP-40/100 motor pumps are a striking example of such fire-fighting installations. There is an option with a tank for extinguishing foam.

Compared to conventional motor pumps, this technique:

• gives a stronger pressure;

• provides solid performance;

• reliable enough;

• comfortable for everyday use.

The ground clearance of the motor pump is 44 cm. At the same time, it can move at a speed of up to 30 km / h. Transportable foam concentrate stock - 200 kg.

The Hyundai HYH 50 petrol pump can also be used for fire prevention purposes. The manufacturer gives it a one-year warranty.

The maximum output per minute is 500 liters. The kit includes only original motors of the Korean concern. The body is made of durable aluminum. Thanks to three outlets, it is possible to use the pumping unit in normal or high-pressure mode.

You should, of course, be guided by the instructions for use offered by the manufacturer. But labor protection requirements are also of great importance.

In addition, the use of pumping units is not allowed if the tank or pipeline leaks at least a little.
