A single-stage centrifugal pump refers to a pump with only one impeller. A general single-stage pump has a maximum lift of only 125 meters. It has the characteristics of simple structure, stable performance, high speed, small size, light weight, high efficiency, large flow rate, easy operation and maintenance, etc. Generally, typical horizontal single-stage centrifugal pumps are IS type, IR type, IY type, etc., and vertical single-stage centrifugal pumps are represented by ISG type.

Single stage centrifugal pump types:

There are many types of single-stage centrifugal pumps. Common ones include vertical single-stage centrifugal pumps, horizontal multi-stage centrifugal pumps, stainless steel single-stage centrifugal pumps, etc. Different division methods will produce different types of single-stage centrifugal pumps.

1. Single-stage single-suction centrifugal pump

2. Single-stage double-suction centrifugal pump

3. Horizontal single-stage centrifugal pump

4. Vertical single-stage centrifugal pump

5. Single-stage chemical centrifugal pump

6. Stainless steel single-stage centrifugal pump

7.IS type single-stage centrifugal pump

8.SH type single stage centrifugal pump

9.IH type single-stage centrifugal pump

10.Single stage pipeline centrifugal pump

Single stage centrifugal pump model:

Different industries have different names for single-stage centrifugal pumps, but manufacturers have a set of standardized rules for naming centrifugal pump models. The following are the general rules for single-stage centrifugal pump models on the market:

IS, ISY, ISR, IH, IR, IHF (I: The number is 1, here it means "single stage single suction"; Y is the abbreviation of oil, R is the abbreviation of heat; H is the abbreviation of chemical)

For example: IS, ISY, ISR, IH, IHF, IR100-65J-250B

IS: Indicates single-stage single-suction centrifugal clean water pump, ≦80℃, cast iron material, packing seal;

ISY: Indicates single-stage single-suction centrifugal oil pump (≦100℃) made of cast iron and mechanical seal;

ISR: Indicates single-stage single-suction centrifugal hot water pump (≦100℃) made of cast iron and mechanical seal;

IR: Indicates single-stage single-suction centrifugal hot water pump (≦120℃) made of cast iron, mechanical seal, and requires cooling water;

IH: Indicates a single-stage single-suction corrosion-resistant chemical centrifugal pump (≦120℃) made of stainless steel (304, 316, 316L, 2205), mechanical seal, and requires cooling water;

IHF: Indicates single-stage single-suction corrosion-resistant chemical centrifugal pump (≦120℃). Pump shell material: cast iron, lined with fluorine plastic (F46), suitable for strong acid and strong alkali media.

The first set of numbers: indicates the diameter of the water pump suction inlet, DN100mm;

The second set of numbers: indicates the diameter of the water pump outlet, DN65mm;

The third set of numbers: indicates the nominal diameter of the water pump impeller, ф=250mm;

J: Indicates that the water pump is used at reduced speed. For the same model, the standard speed is 2980r/min, and after the speed is reduced, the speed is 1450r/min; after the speed is reduced, its flow rate, head, and supporting power will all change;

A.B.C.D: The water pump impeller is cut 1.2.3.4... times based on the standard model. The purpose is to meet the different needs of customers and adjust the performance parameters of the water pump by changing the impeller diameter.

Single stage centrifugal pump parameters:

The main parameters of a single-stage centrifugal pump include power and efficiency, head, flow rate, speed, allowable suction vacuum, allowable cavitation margin, etc. The following are the main parameter values ​​of conventional models of single-stage centrifugal pumps:

Single stage centrifugal pump structure:

The single-stage centrifugal pump includes a pump body, a pump cover, and a motor with an output shaft. The pump shaft, bearing seat, impeller, mechanical seal, and mechanical seal gland installed in the pump body are connected to the motor through an extended elastic coupling. The direction of rotation of the pump, viewed from the driving end, is clockwise.

Single stage centrifugal pump uses:

1. Water supply: water plant filtration and transportation, water plant district water delivery, main pipe pressurization, and high-rise building pressurization.

2. Industrial pressurization: process water system, cleaning system, high-pressure flushing system, fire protection system.

3. Industrial liquid transportation: cooling and air conditioning systems, boiler water supply and condensation systems, machine tool accessories, acidic and alkaline media transportation.

4. Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator and swimming pool water treatment system.

5. Irrigation: farmland irrigation, sprinkler irrigation, drip irrigation.

The difference between single-stage centrifugal pump and multi-stage centrifugal pump:

1. A single-stage pump refers to a pump with only one impeller;

2. Multi-stage pump refers to a pump with two or more impellers.

Compared with single-stage pumps, the difference is that multi-stage pumps have more than two impellers, which can absorb and pressurize water in multiple stages, thereby lifting water to a very high position. The lift can be increased or decreased according to the number of stages of the water pump impellers. Multi-stage pumps are mainly used for mine drainage, urban and factory water supply, and are rarely used for agricultural irrigation. They are only suitable for water lifting in high-lift, small-flow mountainous areas to solve the drinking water problem for humans and animals.
