Do not be fooled by imitation "industrial" pumps sold elsewhere. The pump quality is not the same and as with any pump parts will be needed and PumpBiz stocks parts to all the pumps we sell and support. These are the same pumps used by many rental stores, so they have proven themselves many times over. Hard, siliconized graphite seal faces stand up to abrasive material found in construction and drainage applications.6dly5
