9 SER D OPERTG MUL ersa-surge Suppressor Models T/ T25/ TD½/ TD40/ T2/ T50/ 3/ T80 Metallic Construction OPERTG D SER STRUCTOS This ersa-matic ersa-surge is a completely automatic diaphragm fitted surge suppressor to reduce the flow and pressure pulsations in a pumping system characteristic of reciprocating type pumps. Principle of Operation: The Surge Suppressor uses a flexible diaphragm to separate a liquid chamber from compressed air chambers. rod connected to the center of one diaphragm activates the air inlet and exhaust valves, which automatically admit or exhaust air in the air chambers. This maintains the diaphragms in midrange of stroke for maximum surge suppnession. nstallation: Locate the Surge Suppressor in discharge piping as close as possible to the pump. The unit will operate in any position. Connect the air inlet connection to the air supply line having the same air pressure as that at the air inlet connection to the pump. Do not exceed 25 PS. Service nstructions: When service is required, it is important to MKE RT THT LET R PREURE S DSCOECTED. The diaphragms are serviced by simply removing the hex nuts or v-band, and removing the center spool casting. When irgin PTFE diaphragms are used in conjunction with the elastomeric diaphragms they are placed over the wetted sides of each elastomeric diaphragm. nlet and exhaust air valves are located externally for easy access and service. Warranty: This unit is guaranteed for a period of five years against defective material and workmanship. MPORTT Read these safety warnings and instructions in this manual completely, before installation and start-up of the pulsation dampener. t is the responsibility of the purchaser to retain this manual for reference. Failure to comply with the recommendations stated in this manual will damage the pulsation dampener, and void factory warranty. Minimum are based upon CUTO mechanical stress only and may be significantly altered by pumping certain chemicals. Consult engineering guides for chemical compatibilities and temperature limits. CUTO efore surge suppressor operation, inspect all gasketed fasteners for looseness caused by gasket creep. Re-torque loose fasteners to prevent leakage. Follow recommended torques stated in this manual. WRG efore doing any maintenance on the pulsation dampener, be certain all pressure is completely vented from the pump, suction, discharge, piping, and all other openings and connections. e certain the air supply is locked out or made non-operational, so that it cannot be started while work is being done on the pump. e certain that approved eye protection and protective clothing are worn all times in the vicinity of the pump. Failure to follow these recommendations may result in serious injury or death. Without Suppressor With Suppressor 200 ersa-matic Pump. ll rights reserved.
