"The most reliable offshore fire water pump system today" PUMP DESCRIPTION: The pump is a vertical line shaft, end suction multistage centrifugal pump driven by a high-speed direct injection turbo charged diesel engine. The cooling water taken from pump discharge and the complete system is independent of external cooling water.
A fire pump is tested and listed for its use specifically for fire service by a third-party testing and listing agency, such as UL or FM Global. The main code that governs fire pump installations in North America is the National Fire Protection Association's NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection.
Centrifugal pumps. Centrifugal compressors. ... Especially in irregularly loaded equipment such as extruders, conveyors and crushers. Functions as a torque limiter. Limiting the torque is required to protect the driver and load. Isolation of load from the driver.

Centrifugal pump Curves- Characteristics Continued….. • BHP (Brake Horsepower) and Capacity –For the Centrifugal pump to deliver the capacity we want, we must supply the pump with a certain HP. –Generally, the HP increases as we increase the capacity. • BHP: is the total power required by a pump to do a specified amount of work.
Uses for Centrifugal Pumps. Centrifugal pumps are used in buildings for pumping the general water supply, as a booster and for domestic water supplies. The design of a centrifugal pump makes them useful for pumping sewage and slurries. They are also used in fire protection systems and for heating and cooling applications.
Booster Pumps The centrifugal pump is preferred by the fire protection service due to its ability to fully utilize any positive inlet pressure, reducing the strain on the pump. For example, if the required discharge pressure is 120 PSI (8 BAR), and the inlet pressure is 45 PSI (3 BAR), the pump must only produce the
Floway® VTP (Vertical Turbine Pump) is a vertical close coupled, single and multistage turbine pump which is suitable for multiple applications in various markets. This vertical water pump is available in a variety of material combinations for multiple applications.

Centrifugal Fire Pump Acceptance Test Form Information on this form covers the minimum requirements of NFPA 20-2013 for performing acceptance tests on pumps with electric motors or diesel engine drivers. Other forms are available for periodic inspection, testing, and maintenance.
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action.Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps. Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work moving the fluid.
Increase your understanding and knowledge of centrifugal pumps including their design, selection, operation and maintenance. Moreover, this centrifugal pumps seminar will aid you in increasing productivity and reducing costly downtime. It is important to understand what a pump is and how it works in order to solve problems.

Apr 05, 2019· From NFPA 20, why are pressure relief valves not allowed to control high churn pressure of fire pumps (Sec 184.108.40.206)? And then what is the meaning of the exception A.220.127.116.11 that then allows pressure relief downstream of the discharge isolation valve?
