In some cases, it is possible to pump water by hand pumps. But it is much more efficient, more productive, to use motorized installations for this purpose. We will analyze the advantages and disadvantages, the main features of the use of special pumps of the DaiShin brand.
Let's talk about the DaiShin motor pump SWT-80HX-OA
This version is great for heavily contaminated fluids.
The maximum size of the screened particles is 2.5 cm across. This machine can pump 1300 liters of water per minute. The highest pressure of the liquid is 28 m.
The motor pump is equipped with a gasoline engine, it can pump liquid:
- from trenches clogged with silt and stones;
- from heavily degraded ponds;
- from construction pits.
Allowed the use of this technique:
- as a universal pump;
- in the construction industry;
- in housing and communal services.
The motor, mounted on a mud motor pump, makes the device highly reliable and stable even in difficult situations. The pumping units are equipped with gaskets that make the housing more resistant to wear. An oil level indicator is provided. The pump pumps water from a depth of up to 8 m. Ai-92 brand gasoline is required for pump operation.
This petrol pump is also designed for dirty environments. The device differs from the previous version in increased throughput - it reaches 2 thousand liters per minute. Pump operation is allowed if particles with a cross-section of up to 3.1 cm float in water. The ensured suction is 23 m. Water is drawn in from a depth of 8 m, the total fuel consumption in maximum mode is 1.5 l in 60 minutes.
Another option for dirty water
It's about the DaiShin SWT-100YD model. This pump pumps 1750 liters of water per minute and can create a pressure of up to 25 m. The maximum permissible size of contaminants is 3.1 cm. Liquid can be sucked in from a depth of 8 m. The pump is equipped with a four-stroke diesel engine.
Clean water device
If you need a motor pump for clean water, it is recommended to pay attention to the DaiShin SCR-80HX. This unit will be able to pump 1 thousand liters of fluid per minute. An important limitation: the particles present in the water should not be larger than 0.8 cm. The motor pump raises the column of water to 32 m. The recommended fuel is AI-92; hourly consumption is 1 liter.
When you need to pump slightly contaminated water
In this case, DaiShin SST-50HX is suitable. The motor pump calmly processes the liquid, which contains particles up to 1.5 cm in diameter. Minute productivity reaches 700 liters. The highest head is 23 m. The motor pump is capable of pumping water located:
- in natural reservoirs;
- in flooded basements;
- in wells of various kinds;
- in flooded areas.
DaiShin SCH-5050HX can be used to work with clean and slightly contaminated water. The largest diameter of the transmitted particles is 0.8 cm. 400 liters of water are driven out per minute. The created pressure can reach 50 m. The motor pump is therefore used for fire purposes, to transfer clean liquid over long distances - it is structurally optimized for immediate start-up.
DaiShin SCR-252M2 - a motor pump equipped with a two-stroke gasoline engine, which is cooled by air currents. Lightness and insignificant size allow you to confidently use the device in a summer cottage. Minute productivity is 115 liters.
This amount is enough:
- when watering gardens and orchards;
- during drainage of shallow reservoirs;
- for the purpose of primary fire fighting.
The pump works with clean and almost clean water. The suction and discharge nozzles have a diameter of 2.5 cm. The largest created water column is 35 m. The pump can draw water from a depth of 8 m. The engine uses fuel AI-92 and AI-95.
How to use fire engine pumps
In order for the pump to bring real benefits in extinguishing a fire, it is necessary to supplement it with suction hoses of the required length. The use of hoses without reinforcement is not allowed. They are very easy to stretch and even break. When it is known that a water source precludes complete immersion of the hose, floating filters should be used.
When studying the instructions, special attention should be paid to such moments as:
- storage of a fire pump;
- its installation;
- quick stop in case of emergency.
Installation of motor pumps on uneven surfaces is not allowed. It is undesirable to put them on subsiding grounds. A mandatory requirement is a free approach from any direction. In winter, the motor pump must be stored with fuel draining and oil change. Compliance with all requirements allows you to confidently use the pump for 8-10 years.
What the manufacturer advises when operating diesel motor pumps
Proprietary instructions prohibit their use next to flammable and explosive substances, as well as where fumes of these substances may be present. Operators must be careful not to touch hot surfaces or moving parts. During the running-in period of the pump, it should only be subjected to moderate load.
It is not allowed to use fuel with any impurities, including water. It is also forbidden to operate the pump without a strainer at the suction end.
Advantages and disadvantages of Daishin motor pumps
The designs of this manufacturer are cheaper than the products of competitors. They usually create less noise. However, not everyone may like the increased fuel consumption and reduced resource. To a large extent, these shortcomings are offset by an easy start in any weather conditions. When creating pumps, materials of increased strength are used.
