浓缩塔循环泵浓缩塔泵
NMB、NMBLA、D系列浓缩塔循环泵浓缩塔泵为轴向吸入、单级单吸、托架（悬架）离心式结构，按结构型式分为卧式（NMB、D型）和立式（NMBLA型）两种。该系列泵在水力设计、结构设计上创新节能，过流部件采用抗强腐蚀、强磨蚀的高格耐磨合金铸造，具有高效节能、抗腐耐磨、振动小、噪声低、运行可靠、使用寿命长、维修方便等特点，可广泛用于煤炭、冶金、电力等行业，用于输送含有固体颗粒的腐蚀性、磨蚀性浆体。其固液混合体的最大重量浓度为45%-60%，根据用户需要，可多材质搭配。
该泵泵壳（蜗壳）为单层壳体结构，托架（悬架）采用稀油润滑形式；轴封全部采用机械密封，机械密封采用有冲洗水机械密封和无冲洗水机械密封两种形式。
