The COST €€ of HP METERING PUMPS with Various PULSEGUARD Dampers Increase volumetric efficiency, catch shocks coming back from pipes stop the check valves bouncing, and produce smooth flow. Intercept pressure pulsation, isolate pump excitation from system response. Diaphragm pumps high pressure with multi-layer PTFE are matched with similar PTFE diaphragm pulse dampers having secondary containment sealing. |
13.7 Meters3/hr. being transferred at 1 M/sec through a 3" Sch 80 pipe at 173 pulses/Minute. and 100 Bar (1450psi) produces a 2200 psi pressure swing - which is greater than the 900# flange capability at 250 Degrees F. A 500 in3 900# damper should reduce the pressure swing to 10 Bar. BUT IT DOES NOT. | 5 x 3" 900# @ €175 = €875 3" XH Ts @ €161 = €322 6.5 hrs. fit & weld = €406 4.5 hrs.

The specially single ported "damper" is replaced with a low cost standard twin flanged unit. A "T" is saved, but it is piped "Off-Line". There is no performance improvement - just cost reduction. Our advice was followed "use a Flo-thru" the pressure recorder was protected instead of the system. | 3 Flgs. & 1T €683 4 hrs. fabrication €250 QA & test €180 Standard FLEXFLON twin flanged damper €3,042 2.

A twin flanged 300in3 Flexorber LP was sent, complete with an instrument tap, installed to protect the pump & entire system, works better than the 800 ins3 off line unit. Try asking yourself two questions: 1. Would I invest in a single connection filter? 2. Would I invest in a single connection muffler? |
No Ts no Flgs.
