DJ 500gpm@125psi fire pump package set – ZJBetter

The fire pump is usually equipped with a local control cabinet. The control cabinet does not have a transfer control switch for automatic and manual conversion, but the automatic control loop leaves start and stop contacts, which are connected to the fire alarm system control module. In addition, according to the relevant regulations, the system using the bus linkage control should also be set in the fire control room with buttons that can directly start and stop the pump. When the fire alarm system receives the signal of the fire hydrant start pump button, the control module automatically starts the fire pump and collects its feedback signal.

4. Long service life: The mechanical seal of the fire pump has a long service life and can work stably for a long time.

The lifespan of a fire pump depends on factors like maintenance, usage, and environmental conditions. With proper maintenance, fire pumps can last for several decades.

Horizontal fire pump has significant advantages such as high efficiency, low operating noise, good cavitation resistance, reasonable structure and long service life. , long-distance water supply, heating, bathroom, boiler cold and warm water circulation pressurization, air conditioning refrigeration system water supply and equipment matching and other occasions.

The fire pump can be installed in multiple ways according to the on-site use conditions. And depending on the flow and head requirements, the required flow and head are increased in parallel and series. The bearing adopts low-noise closed bearing, which has been injected with grease before leaving the factory, which can ensure continuous operation for more than two years, and the components have high concentricity. The pump impeller has good performance. Dynamic balance, no vibration in operation, and improved use environment. The pump shaft seal is a mechanical seal, which solves the serious leakage of conventional centrifugal pump packing, increases the service life, and ensures that the operating site is clean and tidy.

The fire pump is mainly used to pressurize and send water to the fire system pipeline. It can also be applied to industrial and urban water supply and drainage, pressurized water delivery for high-rise buildings, long-distance water delivery, heating, bathroom, boiler cooling and heating cycle pressurized air-conditioning refrigeration system water delivery and equipment matching, etc.

The pressure switch and the control cabinet can automatically turn on/off the three pumps, the electric pump and the pipeline pressure pump work when there is electricity, and the diesel pump is started when the power is off.

Three start-up functions for diesel engines:
1. Manual start function: manual and automatic interlocking can be completed through the transfer switch, and the manual start function can be realized:

2. Automatic manual function: allow to start three times. If the startup fails for three times, it will issue a “startup failure alarm” and automatically exit the startup state. After a successful startup, the time from startup to rated load is 5-10-15S (depending on the unit capacity);

3. Emergency manual direct start function: When the automatic control device fails, the emergency manual direct start function can be realized.

The fire booster pump is designed to increase the flow and pressure rate of the water supply coming into the fire system. This is accomplished by drawing water from a municipality main, tank, or hydrant, and then boosting the pressure rate of the water supply with an electric motor and pump. The adjusting of the pressure rate is accomplished by changing the speed of the electric motor that is powering the pump, which in turn changes the amount of water being pushed through the system.
