What are the specifications of PET melt pumps?
The specifications of PET melt pumps are diverse, primarily depending on their designed purposes, processing capabilities, and specific process requirements. Below are some common specifications and parameters of PET melt pumps, but please note that specific specifications may vary based on manufacturers, models, and customization needs.
I. Model Specifications
Common PET melt pump models include, but are not limited to: 1200CC, 3200CC, 4000CC, 6100CC, 8500CC, and 12000CC. These models typically represent the displacement or capacity of the pump, with CC standing for cubic centimeters, indicating the volume of melt that can be delivered per revolution of the pump.
Zhengzhou BATTE Melt Pump Co., Ltd. offers a comprehensive range of PET melt pump specifications, ranging from 0.08CC to 20000CC, and can also provide non-standard customization according to user needs.
II. Technical Parameters
Viscosity Range of Conveyed Medium: PET melt pumps generally have a wide range of viscosities they can handle, such as 1 to 30,000 Pa•s (or expressed as 1,000 to 30,000,000 cP), and some products can even reach 1 to 200,000 Pa•s, like those from Zhengzhou Haike Melt Pump Co., Ltd.
Head and Flow Rate: Specific head and flow rates depend on the pump model and design. For instance, a certain model of PET melt pressure-boosting gear pump can achieve a head of up to 3m and a flow rate of up to 3m³/h.
Power and Rotational Speed: The power and rotational speed of the pump are also crucial technical parameters. For example, a certain model of PET melt pressure-boosting pump has a power of 7Kw and a rotational speed of 30r/min.
III. Materials and Structure
Pump Body Materials: Common materials for pump bodies include high-temperature tool steel, stainless steel, chromium-nickel alloy steel, among others, which exhibit excellent heat resistance and corrosion resistance.
Gear Materials: Gears are typically made of nitrided steel or stainless steel to enhance wear resistance and prolong service life.
Seal and Heating System: Seals often adopt mechanical seals made of hard alloy, which are wear-resistant and provide excellent sealing effects. The heating system mostly utilizes thermal oil heating to maintain an appropriate temperature for the melt during transportation.
IV. Application Scenarios
PET melt pumps are widely used in production lines for PET plastic films, sheets, plates, and other products. Particularly when producing highly oriented and high-quality PET products, the stability and precision of the melt pump become particularly crucial.
In conclusion, the specification parameters of PET melt pumps are diverse, and the specific choice should be made comprehensively considering actual production process requirements and equipment performance. When purchasing, it is recommended to consult professional manufacturers or suppliers for more detailed technical information and product recommendations.
