The COST €€ of PROGRESSIVE CAVITY PUMPS with Various PULSEGUARD Dampers Removing pipe kicks from Progressive Cavity pump systems,"Damping" method selection for most effective and least cost. PC / Progressive Cavity pumps for viscous fluids mate with inline flow through flushable dampers. |
 |
| NOT GOOD Not good because the flow fluctuation that the system mass and friction turns into pressure pulsation will still leave pressure pulsation in the system, because of the pressure change necessary to reverse a highly viscous fluid up and down a single connection. Attempts to overcome this problem with humungus big hole dampers, are too expensive - (and not in place flushable either). |

| LESS EXPENSIVE ! BUT NOT GOOD Damper with inlet directly in line with the flow fluctuation is smaller and works better. Costs less because standard 2 hole off shelf inventory item, use of other connection for RV or vent save purchase of another "T" plus flanges. |

|
| AND THE ANSWER IS: Dampers with 3" through 12" connection; flushable, even "ram rodable" clear flow through path are a standard item in the PumpGuard range. For highly viscous materials, and experience up to gel with 1,000,000 cP viscosity, PULSEGUARD ensures performance at minimum cost, with the PumpGuard range. |
