How to Build a Centrifugal Pump Curve Part 5: Net Positive Suction Head

How to Build a Centrifugal Pump Curve Part 5: Net Positive Suction Head

We are almost finished building our e-1510 pump curve! In this final blog of our series, we’ll introduce positive suction head (NPSH) to our curve and explain what NPSH is and why it matters....

Avoiding Pump Cavitation in Open Systems: How to Determine NPSHA and NPSHR

Avoiding Pump Cavitation in Open Systems: How to Determine NPSHA and NPSHR

In our previous blog we explained the physics behind that noisy, destructive phenomenon known as cavitation – the result of too little NPSH at the suction of the pump. Today we’re going to dig a little deeper into…

Cooling Tower Suction Piping Guidelines

Cooling Tower Suction Piping Guidelines

When designing cooling tower suction piping, it is absolutely critical that engineers have sufficient NPSH to the condenser water pump and avoid any piping design errors that could cause air to come out of the pumping solution.  If either of these becomes a problem…
