With the development of science and technology, pumps at various levels have emerged endlessly and have been widely used. Some friends do not know about single stage pumps and vertical multistage pumps. Today the pump industry will introduce the difference between single stage pumps and multistage pumps.
Single stage pump refers to a pump with only one impeller, and the head is only 125 meters; multistage pump refers to a pump with two or more impellers, and the head can exceed 125 meters.
Vertical Multistage Pump 
Vertical Single Stage Pump
Compared with single stage pumps, multistage pumps have more than two impellers, which can segment and multistage fire pumps to pressurize and absorb water multiple times, which can achieve a high head and thus lift water at a very high position, the head can increase or decrease the number of stages of the pump impeller as required.
There are two types of multistage pumps: vertical multistage pumps and horizontal multistage pumps. Multistage pumps rely on the change of pump cavity volume to achieve suction, exhaust and compression; due to its special characteristics, Compared with single stage centrifugal pumps, multistage centrifugal pumps have higher technical requirements in terms of use, design and maintenance.
Multistage pumps are mainly used in urban and factory fire pump water supply, mine drainage, petrochemical, fire protection, chemical, power, construction and other industries. In terms of agricultural irrigation, it is only suitable for small flow, high-head high mountain areas to solve the problem of drinking water for humans and livestock. In terms of the choice of the two pumps, we can comprehensively consider the factors such as the price of the pump and the area of the room. We should choose a single stage pump or a multistage pump. Multistage pumps are generally more expensive than single stage pumps.
Horizontal Multistage Pump 
Horizontal Single Stage Pump
With the advancement of technology, a single stage impeller pump can increase the pump’s head by increasing the speed of the pump, which can replace a multistage pump, of course, the price will also increase. The differences between single stage pumps and multistage pumps have been introduced above, and everyone has a certain understanding.
