This pump combines the advantages of self-priming pumps and chemical pumps, and is synthesized with corrosion-resistant materials. It has the advantages of self-priming function, thermal protection, smooth running, long time continuous idling and long time continuous load running. Small volume, small current, high pressure, low noise, long service life, exquisite design and other advantages. It has the performance of oil-resistant, heat-resistant, acid-resistant, alkali-resistant, corrosion-resistant, chemical-resistant and so on. The pump body is separated from the motor, and there are no mechanical parts and no abrasion in the pump body., Manufacturer: CCZRD
