Section 1: Advantages of Sanitary Screw Pumps:
1) Sanitary-grade standards, fully polished stainless steel, customizable cart funnel available.
2) Wide range of liquid types and viscosity; offers customizable variable speed drives, including electromagnetic speed control.
3) Even flow with minimal vibration and low noise.
4) Less sensitive to incoming gases and debris compared to other centrifugal pumps.
5) Solid structure, easy installation and maintenance.
II. Working Principle:
The Sanitary Screw Pump is a new type of pump operating on the reciprocating meshing volumetric principle. Its main working components are the eccentric screw (rotor) and the fixed sleeve (stator).
Due to the unique geometric shapes of the two components, they individually form separate sealed cavities. The medium flows uniformly in the axial direction, with low internal velocity, constant volume, and stable pressure, thus preventing the formation of eddies and disturbances. Each stage of the pump outputs a pressure of 0.6 MPa and a head of 60m (clean water), suitable for transporting media with temperatures below 80℃ (special requirements can reach 150℃).
Due to the stator being made from various elastic materials, this pump possesses unique features for handling high-viscosity fluids, as well as transporting media containing hard suspended particles or fibrous materials, which are not typically handled by standard pumps. Its flow rate is directly proportional to its rotational speed.
Transmission can be achieved through a coupling for direct drive, or by using a variable-speed motor, V-belt, transmission box, and other devices for speed variation.
This pump features few parts, a compact structure, a small size, easy maintenance, and its rotor and stator are the components prone to wear, with a simple design for easy assembly and disassembly.
III. Product Advantages:
Comparison with Advantages of Other Pump Types
1. Compared to centrifugal pumps, single screw pumps do not require valves, offering a stable linear flow rate.
2. Compared to diaphragm pumps, single screw pumps can handle various media containing mixed impurities, gases, solid particles, or fibers, as well as various corrosive substances.
3. Compared to gear pumps, single screw pumps can handle high-viscosity materials.
4. Unlike plunger pumps, diaphragm pumps, and gear pumps, screw pumps are suitable for medication filling and metering.
