screw pump for metering and dosing in the chemical industry

Metering and dosing screw pump is a kind of efficient and precise liquid conveying equipment, which is widely used in environmental protection, chemical industry, food and other industries for precise material conveying and metering dosing.
It is characterized by low pulsation, low noise, high precision, easy maintenance, etc. It is suitable for processes requiring high precision metering. The compact design and installation without independent base provide customers with an economical and easy-to-operate solution.

screw pump Main features:

1. Continuous low-pulsation delivery: metering dosing pump provides continuous, low-pulsation delivery to ensure stable flow without adverse effects on the material, suitable for applications requiring high-precision flow control.
2. Low mechanical vibration, low noise: the use of precision-designed pump body and internal components to ensure that the mechanical vibration is small, low noise, suitable for use in noise-sensitive working environments, and at the same time extend the service life of the equipment.
3. The flow rate is proportional to the rotational speed, suitable for metering: the flow rate of the pump is proportional to the rotational speed, which can accurately control the flow rate, and is suitable for the metering and dosing of pharmaceuticals or other materials.
4. Conveying accuracy up to ± 1%: metering and dosing pumps have high precision conveying ability, conveying accuracy up to ± 1%, to ensure that in a variety of applications can be realized in the precise dosage of pharmaceuticals, to avoid waste.
5. No independent base, reducer foot foundation fixed: the use of reducer foot as a foundation fixed, the pump body does not need an independent base, simplifying the installation process, saving space and cost, while facilitating routine maintenance.

screw pump Technical parameters:

• Flow rate: Minimum up to 2L/h, adapt to different flow requirements, suitable for small flow accurate dosing.
• Pressure: up to 12 bar, to meet the needs of high-pressure working conditions.
• Rotor: The rotor is coated with anti-wear, corrosion-resistant design, providing a variety of materials to choose from, including 420, 304, 316, 316L, 2205, Cr12mov, etc., to adapt to the needs of different fluid transportation.
• Stator: NBR, EPDM, FPM, wear-resistant NBR and other materials to ensure the corrosion resistance and durability of the pump body.
• Shaft seal: standard single end mechanical seal, low friction resistance, low temperature, high temperature, corrosion resistance, wear resistance, sealing effect is stable and reliable. According to the actual working conditions, other types of single/double end mechanical seals, assembled or other types of machine seals can also be selected, and even improve the packing seal.
• Reducer: Standard with R series helical gear hardened gear reducer, with high load carrying capacity, high efficiency and long service life, suitable for high load conditions, reducer brand can be selected according to customer needs.
• Motor: Provide a variety of motor options, including three-phase AC motors, three-phase frequency conversion motors, three-phase explosion-proof motors and three-phase frequency conversion explosion-proof motors, etc., to adapt to different working environments and needs. The motors can be selected according to the brand specified by the customer, and provide high energy-efficiency motor options.

screw pump Main uses:

1. Environmental protection industry: used in sewage treatment, waste gas treatment and other environmental protection projects, precise injection of chemicals.
2. Chemical industry: used in the production process of the chemical reaction of raw materials added accurately.
3. Water treatment industry: can be used in the water treatment process, the precise addition of chemicals to ensure that the water quality treatment effect.
4. Food industry: can be used for food additives, flavorings and other substances added accurately.
5. Other industries: applicable to any liquid materials that need to be accurately metered and transported.
