Unless the piping runs are very, very short, generous pulsation dampers are best used at both the inlet and discharge ports. Failure to use generously sized pulsation damers is almost always an invitation to operating problems.
Valuable advice from a professor many years ago: First, design for graceful failure. Everything we build will eventually fail, so we must strive to avoid injuries or secondary damage when that failure occurs. Only then can practicality and economics be properly considered.
