1. ISWB eksplozijas aizsargājamā horizontālā centrifugālā sūkņa aprakstsISWB eksplozijas aizsargājamā horizontālā vienpalpnīgu vienas ieejas centrifugālā sūkņa galvenokārt sastāv no sūkņa, motora un pamata. Sūkņa struktūra ietver sūkņa ķermeni, gultu, sūkņa vāku, mehānisko sargu un citas detaļas, tā ir vienpalpnīgs horizontālā centrifugālais sūkns ar vienu ieeju, kuras sūkņa ķermenis un sūkņa vaks ir sadalīti atpakaļejā gultā, tātad tas ir atverams no aizmugures daļas. Lielākajai daļai sūkņu gultam priekšā un aizmugurē ir aizsargas gredzeni, un gulta aizmugurējā plāksnē ir balansa lubas, lai balansētu aksiālo spēku uz rotora. Sūkņa ieeja ir orientēta uz ass horizontāli, bet izeja ir uz augšu vertikāli. Sūkns un motors ir uz vienas ass, un motora ass paplašinājumam tiek izmantots divu leņķa saskaņojošā bērnlauksu konstrukcija, kas daļēji balansē atlikušo aksiālo spēku sūkņā. Sūkns un motors ir savienoti, montāžai nav nepieciešams korekcijas darbs, tiem ir kopīgais pamats, kuram ir pielietoti JG tipa vibrācijas atbalstītāji. Turklāt šis sūkns ir izstrādāts, pamatojoties uz ISW horizontālā centrifugālā sūkņa modelem, tam ir pievienoti eksplozijas aizsargājamais motors un medeņa gults, lai pārvadītu benzīnu, kerosīnu,
