一、产品概述
HFM系列后吸式滤泵的特色在于：密封寿命长，带压输送岗位(压滤机配用或带压喷淋循环泵)，因为双级加压，料浆泵的叶轮线速度在22~28米/秒之间，即可获得0.8~1MPa的出口压力，而同类单级料浆泵的叶轮线速度在35~40米/秒左右，才能获得0.8~1MPa的出口压力。叶轮线速度下降，在有色冶炼、化工、钛白、非金属矿加工等行业有使用。适用于输送100℃以内的腐蚀性清液或料浆。
二、适用范围
1、可输送100℃温度以内的各类腐蚀性和非腐蚀性清液和料浆或用作各类压滤机加压喂料用泵
2、长期压力运行输送腐蚀性介质的岗位
3、其它泵输送介质时，容易泄漏的岗位
4、需要小流量高压力输送腐蚀性料浆的岗位
