?O CAT3537 kahi cylinder ?ekolu [?ekolu-piston rod] i ho?iho?i maika?i, i ka plunger uku ho?iho?i i loko o ka pihi keleawe alumini a puni, kahi hui kipa 316SS, kahi plunger pūliki pa?a a me kahi hō?ailona NBR [Buna-N] a me O-kani Pahu. ?O kēia mau pākaha piston ki?eki?e he kūpono no nā noi he nui-pū a me nā multi-nozzle, nā ?ōnaehana ki?eki?e ki?eki?e o nā wahi ?enehana a me nā wai wai kūikawā e like me ka pīpī keleawe. [E ?ike pū i ka hana 316SS]

?O CAT pump he mau alaka?i alaka?i no ke kū?ai aku i nā precision ?ekolu cylinder pane hou i nā pulu me nā ?ōnaehana no ka ?oi aku he 40 mau makahiki. Ua ho?okumu ?ia kā mākou hui ma Minneapolis i 1968 e William L. Bruggeman a loea i ka ho?olālā ?ana a kū?ai aku i nā pāna?i ki?eki?e lō?ihi loa a ?oi aku ho?i i ka ?oihana. Ke nānā nei i ka lako koke o nā huahana a me ka lawelawe ?ana i ka mea kū?ai maika?i, nā ?ohana a kā mākou ?ohana a me ka ?oihana i ho?okalakupua iā ia iho i kona kūpa?a i ka maika?i a me ka lō?ihi.

?O kekahi o nā mea ?ike li?ili?i o kā mākou pōmaika?i nui ?o ka ho?olimalima ?ana a me ka mālama ?ana i nā limahana ko?iko?i. ?O kā mākou limahana he pū?ulu mākaukau o nā limahana ?eono i hana pū me ka ?oihana ma mua o 40 mau makahiki a me 14 mau limahana me he 25 mau makahiki o ka ?ike. He limahana lawelawe lawelawe o ka limahana ma mua o 15 mau makahiki. ?O ka ho?olako ?ana i nā lawelawe kū?ai aku ma ke ?ano he mea ma?amau ia no nā limahana āpau.
