Ts'ebetso ea ho pompa ea letoto la JRP Roots e entsoe ka li-rotor tse peli tse bōpehileng joaloka '8' ka phaposing ea ho pompa e potolohang mahlakoreng a fapaneng. Ka karolelano ea koloi ea 1: 1, li-rotor tse peli li lula li tiisa khahlanong le tsona ntle le ho touting le kamore. Likheo pakeng tsa likarolo tse tsamaeang li moqotetsane ka ho lekaneng ho tiisa khahlanong le lehlakoreng la ho qeta le lehlakoreng la ho noa ka phallo ea visous le phallo ea limolek'hule, e le ho finyella morero oa ho pompa khase ka kamoreng.
Ha li-rotor li fumana 1 le 2 ka kamoreng, molumo oa moea o kenang o tla eketseha. Ha li-rotor li fumana 3 ka phapusing, karolo ea molumo oa moea e tla koalloa ho tsoa moeeng. Ha li-rotor li fumana 4, molumo ona o tla buleha hore o tsoe. Ha li-rotor li ntse li tsoela pele, moea o tla tsoa ka har'a sebaka sa moea. Li-rotor li tla rotor ho feta likhoele tse peli hang ha li potoloha.
Phapang ea khatello pakeng tsa lehlakore le kenang le lehlakoreng la pompo ea metso e na le moeli. JRP letoto la metso ea pompo e amohela valve ea bypass. Ha boleng ba phapang ea khatello bo fihla ho palo e itseng, valve ea bypass e bula ka tsela e iketsang.Molumo o mong oa moea o tsoang ka lehlakoreng la phallo o phalla ho ea ka lehlakoreng le ka morao la lehlakoreng le kenang ka valve ea bypass le tsela e khutlisetsang morao, e leng ho fokotsang mojaro oa ts'ebetso ea pompo ea metso le pompo ea pele-pele haholo boemong ba phapang e phahameng ea khatello. Ho sa le joalo, ka lebaka la mosebetsi oa ho laolla ha valve ea bypass e bula, e etsa bonnete ba hore pompo ea "vacuum" ea JRP le pompo ea sethala se ka pele e qala ka nako e le 'ngoe ho qoba boima bo bongata bakeng sa bona ka bobeli.
Pompo ea metso e tlameha ho sebetsoa e le yuniti ea pompo hammoho le pompo e ka pele (joalo ka pompo ea vane e potolohang, pompo ea valve ea li-slide le pompo ea selikalikoe sa metsi). Haeba ho hlokahala hore u fihlele tekanyo e phahameng ea vacuum, lihlopha tse peli tsa lipompo tsa metso li ka kopanngoa ho sebetsa e le karolo ea pompo ea metso e meraro.
