Can anyone help me spec a pump?
Can anyone help me spec a pump?
(OP)
Our suction is 1" discharge is 2"
Right now our pump is designed for 30 gpm but we only need 2-4. Here's what we need
Flow: 2-4 gpm
Pressure: - 100 psi differential
Product: Jet fuel
Suction pressure available: 18 psi
Is this something I can buy off the shelf such as a simple ANSI pump?
Any help is greatly appreciated

Some more info:
Specific gravity is ~0.8, temperature is ~75 F, viscosity ~2.7
Suction pressure is currently at 18 psi, but it is coming through ~1000 equivalent feet of 1" pipe and will therefore drop proportionally with flow. This needs to be validated by engineering, but according to the Cameron Hydraulic Data book, loss in feet would be as follows:
1 gpm 1.41 feet
2 gpm 4.80 feet
3 gpm 9.48 feet
4 gpm 15.9 feet
5 gpm 23.4 feet
6 gpm 32.4 feet
7 gpm 42.6 feet
8 gpm 54.3 feet
If I am doing the calculations correctly, we currently have 18 psi which equates to (18 x 2.31/0.8) roughly 50 feet of head. Our existing pump was designed to operate at ~25 gpm. It also went dry when we ran it, meaning we were likely flowing at or above 7 gpm. It also cannot put up enough pressure
