You chose the efficiency of - a Packed Plunger Pump You have the least pressure pulsation - from a variable stroke metering pump The distance between the end of the plunger stroke and the cylinder head, plus the volume in the suction and discharge check valve pockets, are together less than a quarter of the dead volume of a diaphragm head pump - 1/4 the inefficiency of a diaphragm head. Because of this high efficiency of plunger pumps, the liquid is accelerated progressively, prevents pressure shocks, & provides a smoother flow. Gulp and spurt free smooth dosing with PipeHugger – PHr + PB For constant velocity to the system – 1/8” (3 mm) ID autoclave For pump peak discharge – 0.294” (7.5 mm) ID Seaboard Lloyd For pump peak demands – 3/4” (20 mm) Lense ring For constant suction velocity – 1/2” (12 mm) ANSI or Din flange + PB piping base block provides quick release no pipe disturbance PROBLEM 1. Provide flow thru in place flushability for extruder flush cycle. 2. Intercept pressure transients at 1300 meters/sec & 180 Hz. 3. Reduce the 3 meter per second flow fluctuation to +/- 0.5% ANSWER RESULTS 1. The Coriolis (vibrating tube) mass transfer meter gives accurate readings. Instead of being over excited at its natural frequency of 90 Hz. 3. The flow fluctuations are stabilized to less than a 1% flow swing by the accumulation capability of the nitrogen volume. Dampers that do, flow goes through, pressure problems do not. First address the suction system, no pump can give you smooth flow unless it can fill properly.
