WYT’s NM Type Stainless Steel Screw Pump is a heavy‑duty positive‑displacement unit built with high‑grade stainless steel. It delivers outstanding performance when handling high‑viscosity, abrasive, or shear‑sensitive fluids — including sludge, chemicals, and solids‑laden streams. The corrosion‑resistant stainless body ensures rugged durability in aggressive service conditions, while the progressive‑cavity geometry guarantees smooth, non‑pulsating flow and excellent self‑priming ability. As a result, this pump offers a dependable, low‑maintenance solution that integrates seamlessly into any sewage pump system, proves equally capable in a sewage grinder pump system, and is designed to simplify sewage pump installation — making it a versatile choice for wastewater treatment, food processing, and chemical engineering applications.
Material and Structure
- Material
The pump body and primary wetted parts are manufactured from cast iron or stainless steel, with stainless steel grades (e.g., 304/316) specifically intended for applications demanding superior corrosion resistance. This material selection philosophy is broadly applicable to all types of sewage pump systems, and is especially critical for sewage grinder pump systems where durable materials ensure long‑term reliability. Furthermore, during sewage pump installation, the appropriate material should be chosen based on the actual fluid characteristics to guarantee overall system integrity.
- Structure
Adopting a single screw design, the main working components include the eccentric spiral screw (rotor) and the screw bushing (stator) with a double helix surface on the inner surface. This structure enables the pump to form a sealed chamber, achieving continuous and uniform delivery of liquid.
Product Features
- Strong self-priming ability
This pump has good self-priming performance and can be started without pumping, making it suitable for situations that require self-priming.
- Wide range of conveying media
Capable of conveying various media, including sludge, chemicals, adhesives, petroleum or yogurt, and even media containing solid particles or fibers.
- Stable operation and low noise
Owing to the minimal inertial forces generated by the pump’s internal rotating elements, the unit can operate at elevated rotational speeds while still delivering smooth performance and subdued acoustic emissions. This inherent advantage applies equally to a standard sewage pump system, a heavy‑duty sewage grinder pump system, and even simplifies the overall sewage pump installation process by reducing vibration‑related constraints.
Application Scenarios
Environmental Protection and Sewage Treatment
- High concentration wastewater: Treating papermaking wastewater and food processing wastewater containing fibers and plastic fragments, the single screw structure can stably pass through particulate matter.
- Medication dosing: Transporting chemical agents such as coagulants and disinfectants, with low pulsation characteristics to ensure accurate measurement.
Food and pharmaceutical industry
- High viscosity food: Convey chocolate, syrup, jam, honey, etc., with low shear force to maintain the original characteristics of the material.
- Liquid delivery: Processing ointments and suspensions containing particles to avoid shear damage to materials caused by traditional pumps.
