pump screen

sandra xu The pump screen manufactured by Haixing Co. has several character to make it stand out from other screen:1. The slots are very narrow and precisely sized to keep out even fine sand grains which could otherwise destroy your pump through abrasion. so it can protect your pump.2. Even with narrow slots, the total open area for the water to enter is far higher than any other kind of screen design. More water with lower pumping costs.3. The slots widen inward so sand grains don't wedge and plug. The screen is stainless steel for maximum corrosion resistance. The high open area of a Johnson screen lets the water enter slowly to avoid the problems, such as pressure drops and gases are released allowing minerals to drop out of solutions and form encrustants on the screen surface or erode the screen causing the slots to widen and allowing sand to enter the well. This is why it can be used for longer time.
