1. Connection form

The vertical water pump is connected with the motor by the coupling, which needs to be aligned regularly; the perpendicular water pump is superimposed and connected from the bottom to the top, and the perpendicular water pump is generally called the channel pump.

2. Installation form

Compared with perpendicular water pumps, perpendicular water pumps are easier to install. The vertical pump set is handed with a base, and perfection adaptation is needed after installation.

3. conservation difficulty

Since the perpendicular water pump is composed of upper and lower layers, the conservation of the perpendicular water pump is more delicate. For illustration, to repair the impeller, it’s necessary to remove all the corridor above the impeller before repairing; while the vertical water pump is fairly easy. For illustration, the IS type pump can perform impeller conservation by removing the bay pipe.

4. bottom space

It can be seen from the appearance that the vertical water pump has a base due to its vertical structure, so it occupies a large area.

WXZQ series fire-fighting pneumatic water supply equipment consists of a fire-fighting voltage stabilizer, a fire-fighting pump and an electrical control system.

diesel fire pump set, also known as a diesel engine-driven fire pump, is a type of fire pump system used for fire protection in buildings, facilities, and industrial settings. It is designed to provide water at high pressure and flow rates to fire sprinkler systems, standpipe systems, and other fire protection equipment in the event of a fire emergency. Diesel fire pump sets are an essential component of fire protection systems, especially in areas with unreliable or insufficient electric power supply.

The product is EJ fire pump set. The EJ fire pump set has one electric pump and one jockey pump. The electric pump in the picture is ISW pump. ISW series horizontal single-stage single-suction centrifugal pump is a new generation of energy saving, environment friendly horizontal centrifugal pump researched and developed by our company, which absorbs advanced technology of similar products abroad and adopts domestic
general performance parameters of centrifugal pumps. In addition, according to different operation temperatures and mediums, we developed the hot-water pump (ISWR), corrosion-resistant chemical pump (ISWH) and oil pump (ISWB).

Diesel-driven fire pumps provide a reliable alternative to electric-driven pumps, especially in areas prone to power outages. They offer independent operation without relying on the building’s electrical supply and are often used in remote locations or where backup power is essential.

The application of fire pumps is not only in fire protection systems, but a variety of fire pumps are gradually showing their superior strength in industrial production and urban construction. This includes the implementation and expansion of high-end technologies for industrial and urban water supply and drainage, and high-rise water supply under pressure.

The electric fire pump set is an important fire pump equipment, usually in a horizontal state. Each pump group is composed of five parts: front pump, electric motor, hydraulic coupling, main feed water pump, lubricating oil device (including lubricating oil cooler and working oil cooler. In normal state, two sets are running, one There are two standby pumps, and any feedwater pump set can be used as a standby pump. When one of the two running pumps stops due to an accident, the standby pump will be put into operation automatically.

Diesel engine fire pumps are often used for emergency water supply in high-rise buildings, water companies, steel plants, wineries, chemical plants, hotels, hospitals, and other large-scale projects. Diesel engine fire pump is suitable for unattended emergency water supply system. The product has the characteristics of advanced technology, high degree of automation, superior performance, complete protection functions, reasonable structure, simple installation, and high cost performance. net pressure.
