How To Select Sanitary Volute Pump

Sanitary Volute Pump is a new generation of pump products developed on the basis of introducing foreign advanced technology and combining the use characteristics of our factory's water pumps. It has the characteristics of significant energy saving effect, anti-winding, no clogging, automatic installation and automatic control. The pump has high efficiency and the impeller has been tested for dynamic and static balance, so that the pump has no vibration during operation. It has significant energy saving effect, automatic installation and automatic control, and has unique effects in discharging solid particles and long fiber garbage.
Features of sanitary volute pump products:
1. Strong sewage discharge capacity and no clogging.
2. Reasonable design, small matching motor power, and significant energy saving effect.
3. The sanitary volute pump adopts wear-resistant mechanical seal.
4. Compact structure, easy to move, simple installation, no need to build a pump room, reducing engineering cost.
5. The sanitary volute pump can operate within the full head range without overloading the motor.
6. The center lines of the water inlet and outlet are in a straight line and can be directly installed anywhere in the pipeline.
How to select a sanitary volute pump:
The selection basis of the sanitary volute pump model should be based on the process flow, water supply and drainage requirements, and five aspects should be considered, namely, liquid delivery volume, device head, liquid properties, pipeline layout and operating conditions.
1. Flow rate is one of the important performance data for pump selection, which is directly related to the production capacity and delivery capacity of the entire device. For example, the normal, minimum and maximum flow rates of the pump can be calculated in the process design of the design institute.
2. Liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties. Physical properties include temperature c, density d, viscosity u, solid particle diameter and gas content in the medium, which involves the system head, effective cavitation margin calculation and suitable pump type: chemical properties, mainly refers to the chemical corrosiveness of the liquid medium, which is an important basis for selecting pump materials and which type of shaft seal to choose.
3. The head or pressure required by the device system is another important performance data for selecting a pipeline sewage pump. Generally, the head after enlarging the margin by 5%-10% is used to select the model.
4. The piping arrangement conditions of the device system refer to the liquid delivery height, liquid delivery distance, liquid delivery direction, the lowest liquid level on the suction side, the highest liquid level on the discharge side, and other data and pipeline specifications and their length, materials, pipe fittings specifications, quantity, etc., so as to calculate the system head and check the cavitation margin.

Sanitary volute pump application range: suitable for chemical, petroleum, pharmaceutical, mining, papermaking, power plants and urban sewage treatment, municipal engineering, public facilities sewage discharge and other conveying belt particle sewage.
