APPENDIX PULSAFEEDER ACCESSORIES
I. PULSATROL INSTALLATION, OPERATION AND REMOVAL INSTRUCTIONS
The PULSAtrol is a pneumatically charged diaphragm type chamber that continuously stores energy. Used on
the inlet it will improve NPSH (Net Positive Suction Head available) characteristics of the suction piping
a
system. On the discharge line it will reduce dangerous peak pressures, eliminate shock waves and if of
sufficient volume will reduce pulsating flow to almost linear.
INSTALLATION
Figures 13 a and b
On both discharge and suction lines it is desirable to mount the PULSAtrol as close to the pump connection as
possible. It can be mounted in any position, but vertical is preferred for ease of charging, draining and
servicing. The air chamber is sealed and will not require replenishing regardless of position. A shut off valve
should always be used between the piping system and PULSAtrol, also a drain valve should always be
installed directly below the PULSAtrol. If the discharge line is open to atmospheric pressure then a back
pressure valve should also be incorporated in the system near the PULSAtrol to assure proper operation.
