Pulsation Dampeners at Fluid Flow Control

Fluid Flow Control
Damper with liquid in the bladder, cushion gas (Nitrogen) in epoxy coated shell, fat low profile for high flow large ports. Designed IAW ASME VIII UG 27 & 34 -m. NOTE: PED does not have safety coefficients so can not be complied with. 30,000 PSI Series Pulsation Dampener PulseGuard for the large pipe. Hose, tube, pulsation dampeners. Typical PumpGuard by PulseGuard (since 1978). Clear-Flow flextube pulsation dampener for high viscosity. PulseGuard PumpGuard pulsation dampener. Clear-Flow flextube for food. Hose type pulsation dampener with external bolt rings for applications with large pipe system moments and or requiring large or high pressure rated flanges. For hose and lobe (rotary piston) pumps in 3 inch through 16 inch sludge and slurry pipelines. In line, flow through pulsation dampener for clean liquids low pressure and containing high frequency (above 100 Hz) plus lower frequency volumetric flow fluctuations. The "PermaCushion" foam replaces an air precharge whilst the ceramis "ball pack" breaks pressure pulsation. Pulse Guard, the home of extreme temperature and pressure PTFE and Metal Diaphragm pulsation dampeners. Standard 6000 psi inventory with flow through pulsation interception dampening. Semi-special metal diaphragm for flushibiity in place at elevated temperatures. Made to order jacketed pulsation dampeners for low temperature applications. Direct connection "flow through" flow fluctuation smoother, also intercepts high frequency pressure pulsation from the response of short pipe runs. With elastomer backed diaphragm that imparts some resiliance to the PTFE process side membrane face, for longer life. Pure virgin PTFE diaphragm with bolt on anti-extrusion plate. Pulsation dampener mounted on piping base that stays weled permanently pert of the piping system, 37.5 degree weld preps with the most popular orientation 90 degrees by 90 degrees to damper center line. Pulsation Dampers with corrosion resistant shells that are hydro forged at 10 times their application working pressure. Designed IAW ASME VIII Div 1 Appendix Y and 1 Also available in alloy 20 etc. and alternate diaphragms as shown top right on the main drawing linked here. Damper diaphragm with elastomeric backing for permeation resistance and the 90x90 piping base which stays welded as a part of the pipe system. Pulse Damper, typically deployed for cocoa butter pulsation damping which sets rock hard unless kept at elevated temperature. Typical food and drug trim may include external support rings from 316 / 316L stainless steel and "triclamp" connections. This dampener is being used for tomato paste pumping from a progressive cavity pump and a rotary lobe pump. This drawing will show a pulse dampener, with a PVDF lining (green), with a flow-through in place flushable flanged piping base of plastic. A typical pulsation dampener configuration for some acids etc.. Pulsation dampening unit with direct tubing connections for butt fuzing into a thin wall tube system. This type is serviced in place by removing the top side after taking out the twelve bolts. PulseGuard "FlexOrber LP" dampeners made in many custom configurations. Duplex stainless with GR hubs for hydrocarbons industry. Other configurations that are industry specific available. 7000 PSI series pressure wave interception. Pulse Guard Slimline series pulsation dampeners. Pulse-Guard the original one piece molded no bonds or glue accumulator bladder gas bag, top end reservicable. Poly-Prop Damper PVC dampers 3000 PSI SS 17-4 PH, 30K PSI
