Vertical Multi-stage Fire Pump for fire sprinkler systems

Vertical Multi-stage Fire Pump for fire sprinkler systems

Vertical multi-stage fire pumps are vertical inline multi-stage centrifugal pumps for fire service, composed of vertical explosion-proof motor, multi-stage impeller assembly, mechanical seal and flanged ports. With fire-red anti-corrosion coating, it can be installed directly into fire pipelines. The multi-stage design delivers high and stable head with compact footprint, equipped with overload, phase-loss and overpressure protection. It complies with national fire standards for pressurized water supply of hydrant and sprinkler systems in high-rise buildings.

Product Description

Application Scenarios

Vertical Multi-stage Fire Pump are suitable for places with extremely high requirements for fire water supply reliability, especially when mains power fails, they can operate independently and serve as critical fire protection equipment.

· Civil and commercial buildings: high-rise buildings, large hotels, hospitals, schools, office buildings, supermarkets, commercial residences, etc.
· Public transportation facilities: subway stations, railway stations, airports, various traffic tunnels, etc.
· Industrial and energy facilities: petrochemical plants, power plants, steel mills, docks, oil depots, large warehouses, etc.
· Special and outdoor scenarios: ancient buildings, data centers and other fire‑sensitive places; as well as ships, field operations, unattended emergency water supply systems, etc.

Technical Parameters

· Flow rate and head: The flow rate can reach 40 L/s (at 1.0 MPa). Specific values vary greatly depending on the model and configuration.
· Diesel engine: Typically adopts in‑line 6‑cylinder or V‑type multi‑cylinder four‑stroke diesel engines, featuring high power and high torque.
· Start and control: The control panel supports automatic and remote start. It will automatically start when mains power fails or pipeline pressure drops, and can be put into full load operation within about 15 seconds.
· Monitoring and display: It can display key parameters in real time, such as pump speed, head, flow rate, diesel engine cooling temperature, lubricating oil pressure, fuel level, and battery voltage.

Working Principle
1. The vertical motor drives multi-stage impellers to rotate coaxially after power-on.
2. Water flows through each impeller stage and gains pressure incrementally via centrifugal force.
3. Pressurized water is delivered into fire pipelines for fire-fighting facilities. The control system will shut down the pump automatically under abnormal conditions for equipment protection.

FAQ

Know more about Home Water Supply Systems

Q

My home has weak and unstable water pressure. Will this help?

Yes. Our constant pressure system automatically maintains steady pressure. No more sudden temperature changes while showering.

Q

Does it work during a power outage?

If your system includes a pressure tank (18L or larger), you will still have short-term water supply after power goes out. For longer backup, choose a larger tank.

Q

Is it noisy? Can I install it inside my house?

Noise level is ≤55 dB — about the same as normal conversation. You can install it in the kitchen, utility room, balcony, or basement.

Q

Can I install it myself without a plumber or electrician?

Yes. We provide step-by-step video and photo guides. All you need is a wrench and a standard power outlet.

Q

Do I need to build a concrete foundation?

No. Place it on any flat, solid surface. Rubber pads are included to reduce vibration.

Q

The pump starts and stops too often. What's wrong?

The pressure tank may be low on air. Turn off the pump, drain water, and use a bicycle pump to refill air to 1.5-2.0 bar. If the problem continues, contact us for video support.
