How do you calculate head capacity of a pump?
- IMPORTANT NOTES :
- TOTAL HEAD CALCULATION:
- Total Head = suction Head + Delivery Head. Suction Head calculation = Suction vertical Height ( From Foot valve to Pump Centre) + Horizontal pipe line used + No of Bend (or) Elbow used in suction pipe line.
- Example :-
- Actul. Runnin.
- Actul Total Head. —-
- Head Conversion. Feet.
What is the churn pressure of a fire pump?
The churn pressure is the pressure produced at the outlet of the pump when the pump is running with no water flow occurring in the fire protection system.
How do I choose a fire pump?
How to select a fire pump:
- Gather fire water-supply information.
- Calculate required flow.
- Calculate required pressure.
- Calculate pressure boost required.
- Select pump where flow demand is between 100% and 150% of rated flow.
- Select pump with performance curve where pressure boost is sufficient at flow demand.

How to calculate the head of a pump?
total pump head = height from lowest point to the highest point + friction due to pipes and fitting to the last point + working pressure of the sprinkler
Where is the test header on a fire pump?
A drain valve or ball drip (D) shall also be installed. E= Test Header Connection ŒThe connection for the test header should be between the discharge check valve and the discharge control valve. This allows the fire pump to be tested with the discharge control valve closed, isolating the pump from the rest of the system.
How to visualize running a fire engine pump?
Visualize yourself running the pump on a fire engine. You are standing at the pump level. You are running the throttle out, which increases the RPM’s of the pump, and notice the pressure gauge at the pumppanel increase from 50 PSI to 100 PSI.
