Product Overview

The emergency diesel-driven pump, also known as the intelligent emergency diesel-driven pump, is a mechatronic device specially designed by our company for emergency water supply to industrial boilers in enterprises such as thermal power plants, heat energy plants, and chemical plants. Depending on different operational requirements, the diesel pump can be equipped with either high-quality domestically produced or imported diesel engines, paired with high-efficiency, multi-stage centrifugal pumps. The diesel pump is primarily used for pumping clean water; the temperature of the liquid being conveyed must not exceed 80°C. The flow rate of the conveyed liquid ranges from 5 to 540 m³/h, while the pressure range is from 0.7 MPa to 600 MPa. The配套 power range is from 22 to 900 kW, and the rotational speed ranges from 980 to 2900 rpm. Various types of pump heads can be selected according to specific parameters and operational conditions.

Product Parameters

Scope of application for emergency diesel-driven pump units:

Emergency diesel pump units are commonly used in large-scale projects—including field drainage, high-rise buildings, municipal water companies, steel mills, distilleries, chemical plants, hotels, and hospitals—for emergency water supply. The intelligent emergency diesel pump is suitable for unattended emergency boiler feedwater systems. This product features advanced technology, a high degree of automation, superior performance, comprehensive protection functions, a rational structural design, simple installation, and excellent cost-effectiveness. Depending on the specific application requirements, optional accessories such as control cabinets, four-wheeled trolleys, and rainproof covers can be selected.

Introduction to the Performance of Emergency Diesel Engine Pump Units:

■ Fully intelligent control—automatic patrol inspection; automatic program control; automatic process control; automatic data acquisition and display; automatic fault diagnosis and relay protection.

■ Fully digital direct control (DDC);

■ Comprehensive information display.

The equipment operating status display includes: Standby, Power-on, Oil Supply, Start-up, Start-up Delay, Idling Delay, Normal Operation, Cool-down Shutdown, and Emergency Shutdown.

The equipment operating parameter display includes: pump speed, pump head, cooling temperature, lubricating oil pressure, pump flow rate, running time, fuel level, and starting battery voltage, among other parameters.

The equipment protection settings include pre-alarm functions for the following conditions: overspeed, underspeed, low oil pressure, high cooling temperature, low ambient temperature (below 4℃), low fuel level, low battery voltage, high battery voltage, uncalibrated speed signal, and excessively low water pump pressure or excessive flow rate. Additionally, there are automatic alarm functions for the following conditions: no speed signal, overspeed, underspeed, low oil pressure, high cooling temperature, start-up failure, shutdown failure, open-circuit or short-circuit in the oil pressure sensor, open-circuit or short-circuit in the water temperature sensor, open-circuit or short-circuit in the speed sensor, excessively low water pump pressure, and excessive flow rate.

■ A domestically developed mechatronic design—users only need to connect the inlet/outlet water pipes and the exhaust pipe to get it up and running.

■ The emergency diesel pump equipment is equipped with a communication interface, enabling direct network connectivity with the control center to achieve “four remotes” (remote adjustment, remote signaling, remote monitoring, and remote control) for monitoring and operational record-keeping.

What is your typical delivery time?

Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。

Do you have centrifugal pumps in stock?

Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.

What information should I provide when requesting a quote?

Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.

If you are not sure, don't worry, our business managers will assist you in determining this.

What products do you mainly produce?

Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.

Could you help me with the selection?

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Why is it so slow to get a price quote?

Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
