The vertical centrifugal pump uses a standard vertical motor and quick-install mechanical seal, which is very convenient to replace. The flow-passing parts of the vertical centrifugal pump are made of stainless steel (304\316), which can be used in mildly corrosive media and can replace similar foreign products such as CR and CRN. Vertical centrifugal pumps are widely used in the industry due to their high efficiency, energy saving, stable quality, and wide range of applications.

Vertical centrifugal pump types:

There are many types of vertical centrifugal pumps. According to the number of stages, they are divided into single-stage and multi-stage. According to the material, they are divided into stainless steel vertical centrifugal pumps. According to the application site, they are divided into vertical pipeline centrifugal pumps and marine vertical centrifugal pumps. The following are common vertical centrifugal pumps on the market:

1. Vertical multi-stage centrifugal pump

2. Vertical pipeline centrifugal pump

3. Vertical single-stage centrifugal pump

4. Stainless steel vertical centrifugal pump

5. Vertical self-priming centrifugal pump

6. Lightweight vertical centrifugal pump

Vertical centrifugal pump model:

Each manufacturer names centrifugal pumps differently. Different names may correspond to the same type of centrifugal pump. Although the names are different, the model naming rules of vertical centrifugal pumps still have rules to follow:

1.ISG means single-stage single-suction pipeline centrifugal clean water pump ≦800℃, cast iron material, mechanical seal

2.IRG (hot water pipe pump ≦100℃); cast iron material, high temperature resistant mechanical seal

3.IHG (chemical pipeline pump, equipped with ordinary motor), stainless steel material, mechanical seal

4.IHGB: Chemical pipeline pump, made of stainless steel, mechanical seal, equipped with explosion-proof motor

5.YG (pipeline oil pump, cast iron material, mechanical seal, equipped with explosion-proof motor),

6. The first set of numbers: indicates the oral channel (the entrance and exit are the same), unit: mm;

7. The second set of numbers: indicates the diameter of the impeller, unit: mm;

8. (I): Models without (I) are standard models, with (I) indicating expanded flow, referred to as "expanded flow"; after expanded flow, the flow rate is doubled, the head remains unchanged, and the supporting power is increased;

9.A.B.C: 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.

Vertical centrifugal pump parameters:

The main control parameters for the selection of vertical centrifugal pumps are the pump's flow rate Q, head H, efficiency η, power, speed n, working pressure, required cavitation allowance (NPSH), etc. The following are the main parameters of conventional models of vertical centrifugal pumps:

Working principle of vertical centrifugal pump:

The mechanical energy of the prime mover is transferred to the liquid by the action of the rotating impeller on the liquid. Due to the action of the centrifugal pump, when the liquid flows from the impeller inlet to the outlet, its speed energy and pressure energy are increased. The liquid discharged by the impeller passes through the pressure discharge chamber, and most of the velocity energy is converted into pressure energy and then transported along the discharge pipeline. At this time, a vacuum or low pressure is formed at the impeller inlet due to the discharge of liquid. The liquid in the suction pool is pressed into the impeller inlet under the action of liquid surface pressure/atmospheric pressure, so the rotating impeller continuously sucks in and discharges liquid.

Vertical centrifugal pump structure diagram:

The basic structure of vertical centrifugal pump is vertical structure. The basic structure of a single-stage single-suction vertical centrifugal pump mainly includes a volute-shaped pump casing, a pump shaft, an impeller, a suction pipe, a pressure pipe, a bottom valve, a control valve, a feeding funnel and a pump seat.

Vertical centrifugal pump application range:

1. Main pump of variable frequency water supply system.

2. Ordinary water supply and boiler water supply.

3. For high-pressure washing, R/O filter device.

4. For hot and cold water circulation.

5. Manufacturing engineering equipment and beverage processing equipment.
