Submersible Pump Models
Overview of submersible pumps: (1) When selecting a well-used submersible electric pump, the frame number of the electric pump should be determined according to the diameter of the well (100mm, 105 mm, 200 mm, 250 mm, 300 mm, etc.), and then according to the actual flow and head of the well. Specific specifications and models. …...Read more -
Water Pump Material Introduction
Introduction to stainless steel In layman’s terms, stainless steel is steel that is not easy to rust. In fact, some stainless steels have both rust resistance and acid resistance (corrosion resistance). The rust resistance and corrosion resistance of stainless steel are due to the formation of a chromium-rich oxide film (passivation film) on its surface. …...Read more -
