ʻO ka PST maʻamau centrifugal pump (ma hope aku i kapa ʻia ʻo ka pauma uila) nā mea maikaʻi o ka hoʻolālā paʻa, ka leo liʻiliʻi, ka helehelena nani, kahi hoʻonohonoho liʻiliʻi, ka hana paʻa, ke ola lawelawe lōʻihi, ka maikaʻi kiʻekiʻe, ka hoʻohana haʻahaʻa haʻahaʻa, a me ka hoʻonani maʻalahi. A hiki ke hoʻohana i ka moʻo e like me ka pono o ke poʻo a me ke kahe. ʻEkolu mau ʻāpana o kēia pauma uila: kahi kaʻa uila, kahi sila mechanical, a me ka pauma wai. ʻO ke kaʻa kaʻa he hoʻokahi-phase a ʻekolu-phase asynchronous motor; Hoʻohana ʻia ka sila mechanical ma waena o ka pauma wai a me ka kaʻa, a ʻo ke kumu rotor o ka pauma uila i hana ʻia me nā mea kila kalapona kiʻekiʻe a kau ʻia i ka anti-corrosion treatment e hōʻoia i ka ikaika mechanical hilinaʻi, hiki ke hoʻomaikaʻi maikaʻi i ka lole. a me ka pale ʻana i ka corrosion o ke kumu. I ka manawa like, he mea maʻalahi no ka mālama ʻana a me ka wehe ʻana o ka impeller. Hoʻopaʻa ʻia nā sila hope paʻa o ka pāpaʻi me nā apo hoʻopaʻa paʻa "o" e like me nā mīkini hoʻopaʻa paʻa.
