We have three kinds of pumps for you to select, peripheral pump, centrifugal pump and Jet pump. Suppose all kinds of pumps of a same power: peripheral pump would provide a higher Head but lower Capacity than centrifugal pump and Jet pump. It can get higher Head in an economic way. Centrifugal pump provide large capacity. It has higher efficiency than that of peripheral and Jet pump. And it is a good choice for those pumps which expend a lot on electrical power to save energy, And Jet pump series provide more reliable output. Please check feature of each pump in this catalog for detail.

Owning to the atmospheric pressure, for a certain fluid, there is a certain suction head. For example, for water, the maximum suction lift of an ordinary domestic pump is about 8m.Even when the suction pipe would be pumped to vacuum, it would be about 10M high suction head only. However, choose a deep well pump instead when a deeper suction-15m for example is required. Because Deep well pump consists of two parts, Jet pump and Centrifugal pump. Its deeper head come from the combination of Jet pump's head and centrifugal pump's suction head. Take care to the NPSH(net positive suction head) when use industrial pump or civilian pump, to ensure the pump's stable and continual operation. But for pumps domestic using, usually we do not take NPSH into consideration.
