結(jié)構(gòu)特點： PNJ,PNJB型泵系單級單吸離心式襯膠泵,可輸送各類不含有尖角的固體顆粒,有腐蝕性的礦漿。具有使用壽命長,結(jié)構(gòu)簡單,運行可靠等優(yōu)點。
型號意義：如2PNJB
2：出口直徑為2英寸(50mm)
P：雜質(zhì)泵
N：泥漿
J：橡膠
B：第二次改進
襯膠泵特點：PNJ,PNJB,PNJF型泵系單級單吸離心式襯膠泵,可輸送各類不含有尖角的固體顆粒的礦漿。輸送礦漿最大濃度不超過65%（重量計）,溫度不得超過60℃。兩種泵結(jié)構(gòu)型式相同,但材質(zhì)不同,PNJF型泵專用于輸送有腐蝕性礦漿。
襯膠泵材質(zhì)：根據(jù)用途不同,PNJ,PNJB,PNJF型泵的泵軸分別用優(yōu)質(zhì)碳素鋼,鎳鉻鋼制成,護套分別為耐磨橡膠,耐磨耐酸橡膠與鋼板合制而成,葉輪為鑄鋼制骨架（25PN,25PNJF型泵為鑄鐵制骨架）分別外襯耐磨橡膠,耐磨耐酸,橡膠制成。
密 封 形式：PNJ,PNJF型泵有填料和付葉輪兩種不同的密封結(jié)構(gòu)（25PNJ,25PNJF型泵只有付葉輪密封結(jié)構(gòu)）。密封結(jié)構(gòu)一般按填料密封供貨。若選用付葉輪密封,訂貨時必須說明。泵用付葉輪密封時,進口灌注高度不超過5米水柱（25PNJ,25PNJF型泵不超過1.5米水柱）。
2PNJB,2PNJFB的排出口可按45°間隔旋轉(zhuǎn)不同方向。4PNJFB的排出口在270°范圍內(nèi)可按45°間隔旋轉(zhuǎn)不同方向。6PNJB,6PNJFB的排出口在270°范圍內(nèi)可按30°間隔旋轉(zhuǎn)不同方向。25PNJ,25PNJF的排出口可按90°間隔旋轉(zhuǎn)不同方向,在沒有特殊說明的情況下,供貨一律為垂直向上出口。泵的旋轉(zhuǎn)方向,從傳動方向看為逆時針旋轉(zhuǎn)。
