The Stainless Steel Sump Screw Pump is a new type of pump that operates according to the reciprocating meshing volumetric principle. Its main working components are the eccentric screw (rotor) and the fixed sleeve (stator). The working principle is that when the motor drives the pump shaft to rotate, the screw rotates around its own axis while also rolling along the inner surface of the sleeve, forming a sealed chamber within the pump. As the screw continues to rotate, the liquid is drawn in and enters the sealed space enclosed by the thread and the pump housing. Under the pressure of the screw, the liquid is then extruded out of the pump body.
Features and Applications
The stainless steel hopper screw pump features the following characteristics:
Simple structure, safe and reliable operation: Due to its compact design, minimal parts, and easy maintenance, it is suitable for various industrial environments.
Wide Range of Applications: Suitable for conveying various high-viscosity media (viscosity up to 37,000-200,000 centistokes) and media containing particles or fibers.
Pressure Stability: Due to the uniform rotational speed of the screw, the flow rate of the liquid discharge is even, ensuring stable pressure.
Material and applicable medium
The rotor material of the stainless steel hopper screw pump includes 40Cr, chrome-plated 45 steel, 38CrMoAl nitriding, and various other materials, while the stator material is selected based on the conveying medium, such as NR natural rubber, SBR styrene-butadiene rubber, and NBR nitrile rubber. This pump is suitable for conveying various media including clean water, wastewater, sludge, and organic coatings.
Parameters and Performance
Parameters of the stainless steel hopper screw pump include pressure 0.3-0.6MPa, flow rate 0-150m³/h, speed 500-960r/min, power 0.75-37kw, head 0-240m, and working temperature -15-200℃. These specifications make it suitable for food and other industries with high hygiene standards.
