**Applications:**
This pump is widely used in the following industries:
1. **Petro-industry:** Thickened oil transfer, oil and gas mix transfer, oil and water separation, waste oil recovery systems, sewage treatment, and polymer transfer.
2. **Chemical Industry & Pharmacy:** Handling pastes, suspensions, emulsions, and liquids containing gas or solid particles.
3. **Environmental Engineering:** Sewage delivery, sludge dewatering, flocculent input, oil-water separation, and desulfurization.
4. **Mineral Products Engineering:** Water gas equipment, titanium white production, kaolin processing, chemical input, grouting, and electrolyte treatment.
5. **Food Industry:** Dairy products, juices, purees, vegetable sauces, meat pastes, condiments, beer, and brewing.
6. **Papermaking Industry:** Raw material equipment, coating processes, chemical dosing, and sludge/wastewater treatment.
**Working Principle:**
The pump operates using an elastic stator with a special helical surface and a rotor with a large lead and deep tooth mesh. This creates a continuous seal line within the stator cavity, allowing the suction chamber to move towards the discharge direction continuously. As a result, the liquid is drawn in and discharged smoothly without pulsation.
**Features:**
1. **Wide Application:** Suitable for transferring all types of flowing and non-flowing materials.
2. **Steady Flow and Pressure:** No pulsation ensures smooth operation.
3. **Adjustable Speed:** Output flow changes with speed.
4. **Strong Suction Power:** Low noise, no leakage, and minimal temperature rise.
**Structure:**
The general-purpose design is ideal for transferring liquids with varying viscosity and concentration across different industries.
**Selection Information:**
To ensure optimal performance, it's essential to provide accurate operational data. Our professional team will recommend the best model based on the medium's properties and operating conditions. Please provide the following details:
- **Medium:** Name, corrosivity, abrasiveness, viscosity, solid content, and working temperature.
- **Operation Data:** Flow rate or range, maximum pressure, and whether the operation is continuous or intermittent.
- **Installation Environment:** Horizontal or vertical installation, fixed or mobile, pipe connection requirements, and explosion-proof needs.
