It is not easy to observe and maintain pump when submersible pump in water.The whole machine soaked with the water is easy to corrosion, so we recommend the suction pump to allow a high degree of suction on the selection of self-priming pump better. Because many people do not understand the pump products, in the face of trying to lower the water or other liquids pumped to the height of the first thought is the submersible pump products, because many users only know that there are submersible pump products, and do not know can Installed in the ground then a suction pipe into a variety of liquid inside and pump suction connection can also be pumped up to a variety of self-priming pump products.
1.If the mobile pumping with self-priming height within 5-9 meters flow 100m3 / h or less you can use small gasoline engine pumps, small diesel pumps.
2.If you need more flow can choose large flow of self-priming pump products.
3.Since the suction height of 5 meters within the flow 30m3 / h head 30 meters below the recommended selection of small stainless steel self-priming pump.
4.If the suction is a corrosive liquid can also be used high-suction suction pump products.
