API-675 versus API-674 pump

asked Oct 16, 2014 in Mechanical by guyredumis (540 points)

Hello all,

I would like to have inputs/comments on selecting a right type of pump for the following conditions:

  • 700GPH @ 8500psig
  • Chemical Injection Pump
  • Service location: West Africa

I think these conditions are too much if I use API-675 pump.

What is your opinion? Thanks in advance for any inputs.

Those conditions will need to be a fixed stroke Hammelmann pump.

An API-675 pump model to do these hydraulics will cost a fortune and is not needed.

Assume this is for your Methanol where you should also be employing the IRCD flow distribution? Assuming so, you don't need the API-675 adjustable stroke (flow) feature as that's handled via the IRCD system.

Hope that helps.
