Single Stage Fire Pump

Material :

Cast iron body

Full Stainless steel

Impeller type :

The impeller of a single-stage single fire pump is a closed impeller, which has two cover plates and is called a closed impeller. This type of impeller has high efficiency and is widely used

Clear water: Single pole fire pumps are most commonly used to transport clear water because water is the most common extinguishing medium and has good cooling and suffocation effects.

Non corrosive liquids with physical and chemical properties similar to clean water: In addition to clean water, single pole fire pumps can also be used to transport non corrosive liquids with physical and chemical properties similar to clean water. These liquids usually refer to liqu

ids that do not contain solid particles and have no strong corrosiveness.

Applicable medium conditions

Solid insoluble content: Suitable for the medium being transported, the volume of solid insoluble should not exceed 0.1% of the unit volume.

Particle size limit: The particle size of solid particles in the medium should not exceed 2 mm3.

Medium temperature: The single pole fire pump is suitable for transporting liquids with a temperature range of -15 ℃ to 120 ℃.

PH value range: suitable for media with pH values between 4 and 8

Introduction

Single Stage Fire Pump is a single-stage centrifugal pump used in fire protection systems. It is mainly composed of a pump body, impeller, shaft, bearing and seal. Its working principle is to drive the impeller to rotate through an electric motor or a diesel engine, generate centrifugal force to suck water from the inlet, and discharge it from the outlet after being accelerated by the impeller, providing the required water flow and pressure. This pump is usually used for the transportation of fire water sources to ensure that sufficient water volume and pressure are provided in the event of a fire to protect the lives and property of personnel.

High-efficiency design
The Single Stage Fire Pump is designed to ensure that the required flow and pressure are provided in the shortest possible time, meeting the high requirements of the fire protection system for water sources. According to the NFPA 20 standard, the flow rate of the pump is 150% of the design flow rate, ensuring that the fire protection system can continuously and stably provide sufficient pressure and flow during the fire rescue process.

Corrosion resistance

The Single Stage Fire Pump is made of stainless steel to ensure its corrosion resistance in various harsh environments. This material selection enables the pump to operate stably for a long time in environments such as high humidity, chemicals or high temperatures, without being affected by corrosion, extending the service life of the equipment. Especially in fire protection applications, the pump may need to be exposed to water or humid environments for a long time. Excellent corrosion resistance ensures that the pump will not affect performance and safety due to material degradation.

Separation design of motor and water pump
The Single Stage Fire Pump adopts a design in which the motor and pump body are separated, and the two are connected by an electrical coupler. A major advantage of this design is that when the water pump or motor fails, there is no need to replace the entire pump unit, only the faulty part can be replaced. This modular design greatly simplifies the equipment maintenance and replacement process, reduces maintenance costs and downtime, and improves the efficiency of equipment use.

Self-protection function
The Single Stage Fire Pump is equipped with advanced self-protection functions. When the pump is overloaded or in other abnormal conditions, it can automatically stop working to avoid equipment damage. At the same time, the pump has an automatic restart function, and once the load returns to normal, the equipment will automatically resume operation. This design enables the pump to reduce the need for manual intervention and the frequency of failures during long-term operation, thereby improving the reliability and safety of the overall system.
