In design of fire fighting pumps, fluid speed is maximum 3 m/sec. To reduce velocity of fluids, eksantric and concantric reduction must be used after inlet and outlet of pumps.
Each pumps have control panel seperately.
Pump body should be GG-25 cast iron or GGG 40 sphere cast iron depends on pressure level.
Pump impeller should be bronze or stainless steel to resist of corrosion
