Submersible slops pump, also called submersible foul water pump, is a commonly used sewage pump placed under water. This pump can ensure the smooth discharge of sewage by tearing and cutting long fibers, bags, belts, grasses, cloth strips, etc. in sewage. It is mainly used to transport liquids containing hard solids and fibrous materials, and particularly dirty, sticky, sliding liquid. Submersible slops pump designed and developed by Runneng has the advantages of compact structure, small floor space, simple installation and maintenance, long continuous running time, no cavitation damage and water drainage. And it is widely used in municipal engineering, industrial sewage, construction and other sewage treatment occasions, discharging sewage, wastewater and rainwater containing solids and short fibers.

An industrial park sewage treatment plant in Dawang Town, Guangrao County was established in 2015 and covers an area of 15,973.41 m2 (23.96 mu). This sewage treatment plant adopts a relatively mature sewage treatment process: pretreatment + A2O + deep oxidation + advanced treatment, and treatment scale is 10000 m3/day. Now the company needs to replace two submersible slops pumps due to aging and deterioration of motor and cable insulation materials. Runneng recommends RN50QW15-10-1.1 type submersible slops pump according to its requirements for water quality, treatment scale, lift, and submersible pump materials.

Submersible slops pump structure description

Submersible slops pump is a special type of vane type pump. Motor that drives pump is integrated with pump, sharing a shaft and sneaking into water. According to power of pump, main components and structures of submersible slops pump are also different. It is mainly composed of an impeller, a volute, a motor stator component, a motor rotor component, a bearing and the like.

In May 2018, our company customized two RN50QW15-10-1.1 type submersible slops pumps for Guangrao customers. After being transported to the site, Guangrao customers checked their models, technical parameters and quality. After confirming the equipments, they were installed in the sewage treatment process and put into use. Treated sewage quality of the enterprise can reach the first-class A emission standard of “Emission Standard for Pollutants in Urban Sewage Treatment Plants” (GB18918-2002), and it can reach implementation plan of “Dongying City Ecological Environment Improvement And Improvement Year (Dongfafa) [2014] Document No. 4)”. Sewage treatment plant expressed satisfaction with efficacy and quality of submersible slops pump produced by our company.
