Inkampani imise iibhentshi zokuvavanya ukusebenza ezisibhozo ukwenza isampulu yeemveliso kumgca wemveliso kwaye ihlole izinto zovavanyo ezinxulumeneyo ngokwemigaqo yokwamkelwa kovavanyo lwemveliso egqityiweyo, ukuze kuqinisekiswe ukuba ukusebenza kweemveliso ezigqityiweyo kuyahlangabezana neemfuno zemigangatho yesizwe. Ukongeza, inkampani iye yaseka iibhentshi zokuvavanya ukuthembeka ezisixhenxe, kwaye iqulunqe "uMgangatho wokuQinisekisa uQinisekiso lwePump" ngokwemigangatho kazwelonke. Ngaphantsi kweemeko zokusebenza ezifaniswayo zabathengi, ixesha eliqhelekileyo lokusebenza elingenazinkathazo / ixesha eliqhelekileyo lokusebenza ngaphambi kokuba ukusilela kokuqala kwemveliso kuhlolwe, kwaye umngcipheko wokuthembeka komgangatho wemveliso ujongwa. Amakhonkco abuthathaka kuyilo kunye nokuveliswa abonakaliswe kwinkqubo yovavanyo, kwaye iimfuno ezifanelekileyo zokukhula okuthembekileyo zibekwe phambili.
