PNJ、PNJB型泵系单级单吸离心式衬胶泵，可输送各类不含有尖角的固体颗粒的矿浆。输送矿浆较大浓度不超过65%（重量计），温度不得超过60℃。两种泵结构型式相同，但材质不同，PNJF型泵专用于输送有腐蚀性矿浆.
根据用途不同，PNJ、PNJF型泵的泵轴分别用优质碳素钢、镍铬钢制成，护套分别为耐磨橡胶、耐磨耐酸橡胶与钢板合制而成，叶轮为铸钢制骨架（25PN、25PNJF型泵为铸铁制骨架）分别外衬耐磨橡胶、耐磨耐酸、橡胶制成。
PNJ、PNJB型泵有填料和付叶轮两种不同的密封结构（25PNJ、25PNJF型泵只有付叶轮密封结构）。密封结构一般按填料密封供货。若选用付叶轮密封，订货时必须说明。泵用付叶轮密封时，进口灌注高度不超过5米水柱（25PNJ、25PNJF型泵不超过1.5米水柱）。
2PNJB、2PNJFB的排出口可按45°间隔旋转不同方向。4PNJFB的排出口在270°范围内可按45°间隔旋转不同方向。6PNJB、6PNJFB的排出口在270°范围内可按30°间隔旋转不同方向。25PNJ、25PNJF的排出口可按90°间隔旋转不同方向，在没有特殊说明的情况下，供货一律为垂直向上出口。泵的旋转方向，从传动方向看为逆时针旋转。
