Diesel Driven Horizontal Split Case Fire Pump Manufacturer

SOW diesel-driven split-case fire pumps are horizontal double-suction centrifugal pumps with integrated base structure. Composed of high-power diesel engine, split-case pump head, cooling system, intelligent electric control cabinet and shock-absorbing base, the unit is painted fire-red for anti-corrosion.
The horizontally split casing allows easy maintenance of impeller and shaft seal by removing the upper cover. The double-suction inlet delivers large flow rate and low axial thrust for stable operation. Powered by diesel, it supports emergency startup during power failure with multi-protection for oil pressure, water temperature and overload. It serves as main fire water supply for large commercial buildings, industrial parks and power plants, also applied in flood drainage and large-scale water supply projects for high-flow, medium-high head liquid delivery.

Product Description

Double Suction Split Case Diesel Fire Pump For Power Plant Fire Protection

Diesel driven split case fire pump, also known as diesel split fire fighting pump, is an emergency fire water supply equipment driven by diesel engine, matched with horizontal double suction split centrifugal pump body. Different from electric fire pumps, it does not rely on municipal power supply, which can provide stable high-flow, high-pressure fire water in power outages, widely used in thermal power plants, chemical factories, oil depots, mines and other industrial places with high fire risk.

Working Principle
1. The unit stays on standby normally, while the control cabinet monitors pipeline pressure and mains power in real time.
2. In case of fire, power outage or low pipeline pressure, the control system auto-starts the diesel engine, which generates rotary power via fuel combustion.
3. The engine drives the double-suction impeller to rotate at high speed, drawing water into the pump chamber from dual side inlets simultaneously.
4. The impeller pressurizes water by centrifugal force, and high-pressure water flows out from the central outlet into fire pipelines for fire hydrants and sprinklers.
5. The cooling system maintains operating temperature, and the control module monitors unit parameters. It triggers alarm and shutdown under abnormal conditions to protect equipment and guarantee uninterrupted fire water supply.

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.
