As ALLWEILER screw pump Of users, shopping Screw pump It is necessary to pay attention to some important technical indicators to ensure that products suitable for your needs are selected. The following are some common technical indicators and their interpretations.

Flow: flow refers to the volume of liquid passing through the pump in unit time, usually in m3/h (m ³/ h) Or gallons per minute (GPM). The proper flow rate is determined according to the volume of the conveying medium required by the user and the working efficiency of the pump. If the flow is too small, the demand may not be met; If the flow is too large, it may waste energy or cause other problems. COLFAX agent

Discharge pressure: discharge pressure refers to the pressure generated by the pump when delivering medium, usually expressed in bar or pound force per square inch (PSI). The discharge pressure index affects the delivery capacity and working efficiency of the pump. When purchasing, it needs to be determined according to the requirements of the conveying medium and the pressure requirements of the system.

Rotating speed: the rotating speed of the pump shaft, usually expressed in revolutions per minute (rpm). The speed directly affects the outlet flow and discharge pressure of the pump. High speed can generally provide greater flow and discharge pressure. However, excessive rotational speed may cause noise and vibration problems, so for specific application scenarios, appropriate rotational speed range needs to be considered. CIRCOR SECCO

Cost effectiveness: Cost effectiveness refers to the selection of products with reasonable price and stable performance on the premise of meeting specific needs. It is necessary to compare the price, performance, quality and other factors of different products to select the most appropriate product. In addition to the purchase cost, it is also necessary to consider the subsequent operation and maintenance costs, service life and other factors.

Material: the material of screw pump directly affects its corrosion resistance and reliability. Different conveying media have different requirements for materials, so materials suitable for specific media need to be selected. Common materials include cast iron, stainless steel, nickel base alloy, etc. Select appropriate materials according to the characteristics of the medium and the working environment.

Sealing mode: the sealing mode of screw pump determines whether it can adapt to different working environments and transmission media. It mainly includes packing seal, mechanical seal and magnetic seal. The chemical property, temperature, pressure and other factors of the medium shall be taken into consideration when selecting a suitable sealing method.

Efficiency: the efficiency index of the pump reflects the effect of energy utilization, usually expressed in percentage. High efficiency pump can reduce energy consumption and operation cost. Selecting an efficient pump can significantly reduce energy consumption, which has a positive impact on the environment and economy. Viking

When interpreting these technical parameters, it is necessary to understand the specific needs and application scenarios of users to determine the appropriate numerical range. At the same time, it is also necessary to consider the reputation of suppliers and product quality, and select professional suppliers and high-quality products.

When selecting the screw pump, the user can refer to the past experience and check the product manual and technical parameter table provided by the supplier. At the same time, you can also consult professionals or relevant departments to understand the performance and scope of application of this product.

In a word, the selection of a suitable screw pump mainly requires attention to technical indicators such as flow, discharge pressure, speed, cost-effectiveness, materials, sealing method and efficiency. A reasonable interpretation of these technical parameters can help users to purchase products that meet their needs ALL WEILER screw pump.
