For Double Layer PTFE Pumps, Double PTFE Diaphragm Dampeners

For flow fluctuation smoothing only:- Inefficient one connection accumulator versions are available at higher cost. How many one connection silencer mufflers, filters, capacitors, have you seen?

Shock Wave and flow fluctuation free with FlexOrber (FLo and SoG) dampener interceptors - Hazard class tell tale port from between primary seal and secondary containment seal Huge dead volume of compressible drive fluid 4 times pumped volume of compressible system liquid, causes lost motion, resulting in shocks

Off the shelf inventory – FlexOrber – with LDi "FlexFlon" modified PTFE With secondary containment sealing, double layer diaphragms, & permeation alert port. Discharge system Shock Interception where EPDM, BunaN, Hypalon, Fluoros, etc. are NOT compatible. Secondary containment sealing and permeation detection optional, Alternates: MTFE (2 layers modified PTFE diaphragms) or VTFE (elastomer backed encapsulated stiffener & virgin TFE) Capacitance + Direction change impedance

FlexOrber + MeterGuard pipe base “MeterGuard”

Not on the shelf inventory – this maintains system integrity when FlexOrber dampeners are serviced or “swapped” and ensures minimum down time.

Metering Pump Pressure Pulsation Dampening

On Typical Diaphragm Metering Pumps

Simply, how it works:

1. Pressure measured at one place in a piping system can be seen approximately 1400 meters away, (o.87 miles away) one second later. That is to say the speed of pressure wave transfer is generally over 3,000 miles per hour.

2. As pressure goes so fast, a piece of pipe, say 15 meters long (approximately 50 ft), reflects it back to source in 0.02 seconds, or say at 50Hz. Another thought is that it will pass a 100 mm "T" branch in 0.00007 of a second! So a one connection dampener on the T can not respond.

3. Frequencies from short lengths of system, must be addressed by flow through dampeners .*

*Flow through, dampeners give:
More Flow Fluctuation Smoothing as well, PLUS
A. Pressure pulse interception
B. Flushability in place
C. Standardization
All at a lower cost!

If for some reason you really must not have these benefits, keep the lower cost, by using one connection and the other saves a "T" for Gauge, Drain, R.V., or Rupture Disk.
