The EHR, ELR, and EMR series pumps also double-casing structure, with the frame plate and cover plate featuring replaceable corrosion-resistant rubber liners (including the impeller, cover plate liner, frame plate liner, etc.). These models share interchangeable frame plate and cover plate with the EHM, ELM, and EMM pumps, while maintaining the same drive components and installation configurations.

The EHM series pump, also known as a heavy-duty slurry pump with thicker wear parts and a heavy-duty frame, is suitable for conveying highly abrasive, high-concentration slurries, low-concentration high-head slurries, and slurries with mild corrosiveness.
The EGM series pump is a cantilevered centrifugal slurry pump suitable for conveying highly abrasive and high-head slurries. It is widely used in mineral processing, metallurgy, coal washing, chemical industry, power generation, dredging, building materials, and municipal engineering, etc. Featuring thicker wear parts (i.e., wet-end parts, including the impeller, volute, throat bush, and back liner) and a heavy-duty frame, the EGM series pump can be used in multi-stage configurations within its maximum allowable working pressure.
The EMM series is a medium-duty slurry pump suitable for conveying fine-particle, medium-concentration slurries or low-corrosive slurries.
The ELM series pump, also known as a light-duty slurry pump, operates at higher speeds and is more compact and lightweight compared to heavy-duty slurry pumps. It is well-suited for conveying fine-particle, low-concentration slurries or corrosive slurries. Typically, the weight concentration of the conveyed slurry does not exceed 30%, and the volume concentration does not exceed 5%.
The EHR and ELR series slurry pumps feature rubber-lined wet parts, making them suitable for conveying fine-particle and corrosive slurries. The cover plate, frame plate, and drive part of EHR and ELR series are interchangeable with those of the EHM and ELM series pumps.
