Jacketed Dampeners for Jacketed Pump Heads. / For Ultra Temp Remote Head Metal Diaphragm Dampeners

A smaller connection dampener will give "course" dampening and a larger dampener, with large connection sizes, will give "smooth" dampening. Where there is no occupational health and safety need for in place flush before servicing, nor process requirement for constant temperature, or 1st in 1st out need to control residence time, not even clean before changing liquids, it is still least expensive to use a standard twin connection dampener , & save a "T". Use the other connection for the system drain, relief valve, or branch line. Waveguard and dampeners for frequencies above 10Hz., Systems shorter than 300 meters (1000 ft.), must use FLOW-THROUGH feature.

Diaphragm Metering Pump Flow Fluctuation Figure

Make a note of this pump's F number, also known as its Flow Fluctuation Figure. Use the F number with the % residual fluctuation required figure from the smoothness shown for each type of application. These two figures, the F figure and the % figure, applied to the size selection formula give you the smallest practicable dampener size.

Find the "F" Valve of Your Pump - "F" is a correction Factor on the square of number of displacers.
Example, Centrifugals are intrinsically good - have a high F, Sandwich diaphragm metering pumps have a low F.
F = 0.8

F for duplex diaphragm heads also = 0.8
A simplex diaphragm head pump is pushed by a 100 mm diameter piston with a 150 mm stroke @ 205 spm
5 cm Piston Radium x 5 cm piston radius x (Pi) 3.142 x 15 cm stroke = 1.18 Liters per stroke @ 3.4 Hz.

Multiplex Diaphragm Pump Flow Fluctuation Figure

Make a note of this pump's F number, also known as its Flow Fluctuation Figure. Use the F number with the % residual fluctuation required figure from the smoothness shown for each type of application. These two figures, the F figure and the % figure, applied to the size selection formula give you the smallest practicable dampener size.

Find the "F" Valve of Your Pump - "F" is a correction Factor on the square of number of displacers
Example, Centrifugals are intrinsically good - have a high F, Sandwich diaphragm metering pumps have a low F.
F = 0.6

Triplex Quad and Quintuplex versions of this type of pump, particularly when used at pressures above 100bar (1500psi), have a phenomenal tendency to create huge pressure disturbances, and high frequencies from interaction within the manifold. The F factor of 0.5 is stated to cause additional dampener size to allow for the greater level of pulsation that might not be expected. Special OCTOPUSSY replacements for the pump manufacturers interconnection manifold are available
