Jiangsu Du'an Environmental Protection LS65-125Pipe centrifugal pump's flow components

PipeCentrifugal pump's flow components include: the suction chamber, impeller, and discharge chamber.

The impeller chamber is the core of the pump, as well as the core of the flow components. The pump increases the liquid's energy through the work done by the impeller.

Impellers are categorized into three types based on the direction of liquid flow: 　　

（1）The liquid from the radial flow impeller (centrifugal impeller) exits in a direction perpendicular to the axis. 　　

（2) The liquid from an inclined impeller (mixed-flow impeller) exits the impeller along a direction tilted from the axis.

（3) Axial flow impeller liquid flow is parallel to the axis.

Propellers are divided into two categories based on the intake method: 　　

（1） Single-suction impeller (meaning the impeller draws liquid from one side). 　　

（2） Double-suction impeller (i.e., the impeller draws liquid from both sides). 　　

（3） Impellers are divided into three categories based on the cover plate form: 　　

（Closed impeller.

（2) Open impeller.

（3) Semi-open impeller.

Closed impeller applications are widespread, and the single suction impeller and double suction impeller mentioned earlier both fall under this category.

Single-stage, single-suction, vertical centrifugal clean water pump, suitable for industrial and urban water supply and drainage, as well as central air conditioning and fire protection systems in high-rise buildings.

Pump is designed for vertical installation with horizontal or axial suction and discharge, the pump inlet is adaptable.Installable in any of the four directions (0°, 90°, 180°, 270°), significantly reducing the occupied area, ideal for use in smaller spaces. Direct coupling of the pump and motor, impeller mounted on the motor shaft, mechanical seal used for the pump shaft seal, and external water flushing provided.

Rotation Direction：

From the motor end, the pump rotates in a clockwise direction.

Complete Set RangeSupply:

Complete sets of pumps, motors, and also provide check valves, gate valves.

Duwan Environmental ProtectionVertical Single Stage Pump is a vertical structure single stage single suction centrifugal pump, also known as quality alloy mechanical seal device due to its vertical structure design. It features high efficiency and energy saving, reliable performance, and easy installation and use. This series of centrifugal pumps is applicable as vertical single stage centrifugal pumps. These centrifugal pumps are designed according to industry standards for performance and dimensions. The shaft seal of this product is suitable for industrial and urban water supply and drainage, and can also be used for agricultural irrigation, for conveying clean water and liquids similar to water, with temperatures not exceedingAt 80°C, you can choose a hot water vertical single-stage pump or a high-temperature-resistant vertical single-stage centrifugal pump for temperatures above 80°C.

Vertical Single Stage Pump Operating Conditions

RPM (Revolutions Per Minute)2960 RPM, 1480 RPM, or 980 RPM

Flow range:1.8~2000m3/h

Flow Rate:≤127m

Medium Temperature:-10℃~80℃

Ambient Temperature: High+40℃

Altitude less than1000m

Relative humidity not exceeding95%

Import Pressure≤0.4MPa

When import pressure exceeds0.4 MPa, or when the system's working pressure exceeds 1.6 MPa (for 125mm diameter at 2-pole speed and below), 1.2 MPa (for 125mm diameter at 4-pole speed and 150-200mm diameter), or 1.0 MPa (for 250mm diameter and above), the overflow components of the pump must be made of spheroidal cast iron or cast steel, with the mechanical seal to be selected separately. For cavitation, the overflow components should also be made of spheroidal cast iron or cast steel, with the mechanical seal to be selected separately. The cavitation margin is the measured value at the design point, and an additional safety margin of 0.5m should be added during actual use. PN16-GB/T17241.6-2008 mating flanges are optional.
