Fire Pump Function

The type of pump used to move water through a fire sprinkler system or to manual hose bibs in a commercial building or industrial plant. The pump’s intake is usually connected to the external water supply, although in some cases it may be connected to a local water source such as a well, tank, or body of water.

The fire pump system, of which the pump is the critical component, is designed to quickly deliver enough water to efficiently douse a fire before it has a chance to spread. In many areas, they are required to be periodically tested and certified by the local fire inspection agency. They are commonly used in buildings with upper floors that are too high to be reached with the pressure of the local water supply, or where there is not enough fire fighting capacity from the local water supply.

They generally work within the following ranges:

Capacity ranges between 20 and 5,000 gpm

Total head (pressure) ranges between 30.5m and 365.8m

Horsepower ranges between 7.5kw and 600Kw

Fire pumps and the rest of the system are required to meet the requirements of NFPA (National Fire Protection Association), UL (Underwriter’s Laboratory), and, in Canada, CSA (Canadian Standards Association). These requirements are quite detailed as to both the hydraulic and the mechanical requirements for the pump, driver, and controls. There are a limited number of NFPA, UL, and CSA approved pump suppliers. Local standards and the owner’s insurance requirements should be studied carefully before selecting a fire pump type and supplier.

Fire Pump working

They are usually centrifugal pumps and are powered by either an A.C. electric motor or a diesel engine. When one of the sprinklers in the building detects a high level of heat, the pump begins working immediately. In some cases, the fire regulations may require a fire pump to have an emergency generator as a back-up in the event of a power failure. Small, portable engine-driven configurations are used in forest fire fighting applications.

Fire pump mechanisms

The most common types are horizontal split case of eu-flo’s EOW and vertical turbine of eu-flo’ FVTE . Some applications for lower flows may include end suction eu-flo’ FIOE or vertical inline of eu-flo’ oh5. Many fire systems also use a jockey pump. This is a small centrifugal pump that runs continuously to keep the fire system piping filled and under pressure. This ensures that the sprinklers will be immediately effective when they are opened and the fire pump is started.

Industrial pumps are widely used throughout the pharmaceutical industry to process, unload, mix and transfer liquids. Since a many different types of liquids need to be handled within the pharmaceutical industry, high-quality, efficient and versatile pumps are required. eu-flo Pumps carries a wide range of pharmaceutical pumps to meet these application requirements.

Our inventory of pharmaceutical pumps includes centrifugal, flexible impeller, diaphragm, rotary lobe and submersible pumps. Other pumps used in pharmaceutical applications include drum and container pumps, used to unload liquids efficiently, leaving little trace of liquid in the container. Stainless steel pumps are also frequently used for pharmaceutical applications due to their corrosion resistant and high-performing capabilities. Browse our pharmaceutical pumps below.

Common contaminants in pharmaceutical processing industries are water and airborne particles/ infections. In pharmaceutical environments, microbial, chemical and human contamination is the major source of contamination. Pharmaceutical industry follows one of the most stringent hygiene standards as compared to food, beverage and cosmetic industries. In the production of pharmaceuticals, hygiene and process reliability are crucial.

Centrifugal pumps are ideal for this kind of work because they are designed specifically to maintain product integrity and consistency. The advantages of using centrifugal pump are:

  • During restriction in liquid flow, a centrifugal pump will max out on the pressure at its dead-head pressure. This will not cause any damage to the system and it is easy to say able to work at medium to low head
  • Can deal with large volumes of liquid
  • Small in size, which saves a lot of space
  • Low capital cost
  • Easy maintenance
  • No danger creates if discharge v/v is closed while starting
  • Is able to work for medium to low viscous fluid
  • Continuous pulsation free delivery

HVAC

Centrifugal pump use in HVACof Pump Supplier in china

The centrifugal pump has long been the workhorse of HVAC systems, supporting the operation of chillers, boilers, cooling towers, domestic water systems, and hydronic distribution systems. And while practically every other component in an HVAC system has been greatly modified to meet ever changing requirements for efficiency and reliability, centrifugal pumps have not changed very much.

That does not mean today’s centrifugal pumps are the same as those of 20 years ago. Manufacturers have made significant improvements in impeller designs, construction materials, bearing and seal designs, and couplings. But these changes have been more evolutionary than revolutionary. 

As a result, many managers simply overlook the pump as an opportunity to improve the performance and reliability of HVAC systems. Building designers replicate designs used in the past in new building designs or renovation plans. System operating practices simply follow past tried and true practices. And when pumps fail, technicians replace them with new ones with the same characteristics.

The situation is changing today. Many advances that have affected other areas of building HVAC operation are being applied to pumps and their operation. As a result, engineering and maintenance managers can achieve levels of operating efficiency that were unheard of as recently as 10 years ago. And while improved operating efficiency is a primary benefits of today’s pump installations, it is not the only one. System performance has improved. Reliability has increased. Maintenance requirements have been reduced.

Improving Pump Efficiency

The overall efficiency of any pump used in a building HVAC system is determined by a number of factors, including:

  • the efficiency of the pump and motor
  • the efficiency of the pump control
  • how well technicians maintain the pump and its related components.Enter the Intelligent ControllerPls do not Overlook Maintenance 
  • No matter how advanced the control system or how good the design, pump systems will operate effectively and efficiently only if managers schedule maintenance properly. Too often, though, they ignore maintenance until something goes wrong.

    The resulting costs from pump repairs and disruption to building operations typically exceed the cost of ongoing pump maintenance by a factor of 10 or more. Maintenance activities and the frequency with which they must be performed vary with the capacity of the pump and the nature of the load that it is serving. 

    One of the most important maintenance tasks is to pay attention to a pump’s operation. Does it look and sound normal, or has it developed unusual sounds or vibrations? Louder-than-normal or unusual sounds can indicate a range of problems, from misalignment and bad bearings to cavitation.

    A small leak rate at pump seals is normal, but a sudden flooding of the area near pump shafts indicates that a seal has failed and needs replacing. Excessive heat can indicate a failing bearing or a motor that might need replacing. By checking the pump regularly, maintenance technicians can identify pump problems early, reducing repair costs and disruptions to operations. Although it might be too late to prevent having to overhaul or replace the pump, at least the maintenance department, rather than the pump itself, will be able to pick the time when the pump is out of service.

    Beyond periodic checks on pump operations, maintenance personnel should follow the manufacturer’s recommended schedule of maintenance activities. But these are the minimum maintenance requirements. Pumps serving critical applications in a building will require additional maintenance activities if they are to enhance system reliability.

    A successful pump installation requires that managers change their ways of thinking about pumps. Sticking with old design and operating practices will prevent the system from operating as efficiently and reliably as it could, and waiting to adopt new technologies that are available means missed opportunities to ensure smooth building operation and enhanced energy efficiency.

  • While VFDs can greatly improve the energy efficiency and control effectiveness of pumping systems, manufacturers have developed a new generation of controls that goes even further. This new generation of pump controls — intelligent pump controllers — offers improvements in pump reliability while further improving system performance.

    Intelligent controls can better adjust to system load changes, better control pump operations, and provide control over a wider range of load conditions, and produce smoother pump startups.
    Intelligent controllers also use VFDs to regulate pump speed, but they do so not as a standalone device, but as another element in the overall building automation system. By connecting the pump and its controller to a digital field bus, data from the pump and its sensors can integrate into the system. Software monitors the operating conditions and identifies conditions that are outside normal operations and those that could damage the pump.

    For example, if the flow to a pump is restricted, the flow rate through the pump decreases. A conventional VFD control systems then signals the pump to increase its speed, possibly resulting in cavitation, a condition that can rapidly damage pump components. In contrast, an intelligent pump controller detects cavitation condition, notifies the operator of the situation, and — if programmed to do so — reduces the flow rate sufficiently to prevent cavitation without shutting down the system.

    Cavitation is just one condition that intelligent controllers can detect. Operators can program the software to detect abnormalities, from sticking control valves to system leaks. Technicians can use the system to identify recurring or intermittent problems that otherwise might go undetected.

  • New pump designs and high-efficiency drive motors can improve operating efficiency. For example, by replacing a pump motor with a high-efficiency model, managers can achieve a reduction in energy requirements of 1-5 percent. Similarly, installing a high-efficiency pump can reduce energy requirements 1-3 percent. While these efficiency improvement numbers are relatively small, the typical annual hours of operation for many pump applications can make the resulting savings very significant.

    While using higher-efficiency pumps and motors will improve operating efficiency somewhat, the greatest improvements in efficiency come from new designs of pump controls. Traditional pump installations use constant-speed pumps. Technicians use building, balancing, throttle or bypass valves to reduce flow when demand is low or to balance the flow to different areas of the building. 

    These valves restrict the flow of water through the end device, but the pump still uses the same amount of energy to operate. Also, technicians tend to set these valves and forget them. Conditions and loads change in a building, but the valve setting remains the same.

    An alternative to throttling flow that improves both performance and energy efficiency is the use of variable-frequency drive (VFD). VFDs have slowly gained acceptance in use with building HVAC pumps because of their ability to effectively control the operation of a pump over a wide range of flow requirements, while also significantly reducing the energy requirements for the pumping system.

    For example, as control valves cut back on the flow of water through terminal heating or cooling devices, the control system senses the reduced flow requirement and directs the VFD to reduce the pump speed to match the conditions found. Since the vast majority of systems operate at loads below peak capacity 95 percent of the time or more, VFDs can greatly reduce pumping energy requirements. In a typical HVAC application, pump energy savings typically are 20-50 percent annually.
