Netzsch Progressive Cavity Pump packing seal

Screw Pump Packing Seal: Functions, Application Scenarios, Advantages and Disadvantages

1. Main Functions

Shaft end sealing: Seal the gap between the drive shaft and pump housing of the screw pump to prevent medium leakage.

Air intake prevention: Block outside air from entering the pump cavity to avoid pump dry running, flow reduction and cavitation.

Dust and impurity prevention: Prevent external dust and particulate impurities from entering bearings and the pump interior, protecting the rotor, stator and bearings.

Vibration damping and buffering: Provide certain buffering and compensation for slight shaft eccentricity and pump vibration.

2. Application Scenarios

Suitable for clean water, sewage, sludge and general low-corrosive chemical media.

Applicable to low-speed single screw pumps / triple screw pumps under normal temperature and medium-low pressure.

Ideal for working conditions allowing slight dripping (minor leakage is permitted for lubrication in normal operation of packing seals).

Widely used in water supply and drainage, sewage treatment, papermaking, food slurry and general industrial conveying conditions.

Suitable for equipment with limited budget, simple maintenance requirements and on-site quick replacement demands.

3. Advantages

Simple structure, low cost and affordable spare parts.

Easy installation and maintenance; no professional tools required. The packing can be compressed or replaced on site at any time.

Strong adaptability to slight shaft wear, eccentricity and coaxiality deviation.

High temperature resistance; compatible with multiple materials (graphite, PTFE, aramid, asbestos-free alternative packing, etc.).

Good resistance to particles and dirty media, not easy to be stuck by fine particles.

4. Disadvantages

Ordinary sealing performance, unable to achieve zero leakage; slight dripping is inevitable during normal operation.

High friction power consumption, causing wear on the pump shaft and shaft sleeve after long-term operation.

Regular manual compression and packing replacement are required, leading to high maintenance frequency.

Not suitable for high pressure, high vacuum, flammable, explosive and high-value media (leakage may cause safety hazards or material loss).

Available in aramid, PTFE, graphite and more materials for different application scenarios.

Screw Pump for High Viscosity Fluid – Sludge/Grease/Melt Transfer, Stable Non-Pulsating Flow

-Engineered for Thick Media, Solving Centrifugal Pump Clogging & Unstable Flow Issues, Ideal for Food/Chemical/Oil Industries

Looking for an efficient solution for high viscosity fluid transfer? Our screw pump is your top choice. Designed for thick media like sludge, grease, polymer melt and heavy oil, it adopts advanced stator-rotor meshing technology to deliver continuous non-pulsating flow. It completely solves the problems of low efficiency and frequent clogging of centrifugal pumps in high viscosity working conditions. Its gentle transfer method maximizes the integrity of shear-sensitive fluids, making it widely used in food processing, chemical manufacturing, oil & gas and other fields.

1.Continuous Non-Pulsating Flow, Preserving Fluid Integrity

The progressive cavity stator and rotor mesh precisely, ensuring smooth and gentle transfer. It avoids damaging the properties of shear-sensitive fluids such as food sauces and polymer solutions, and ensures stable product quality.

2.Clog-Resistant Structure, Adapting to Complex Thick Materials

The wide flow channel design combined with spiral propulsion structure can easily handle high viscosity fluids with particles, eliminating the need for frequent cleaning and maintenance and reducing downtime costs.

3.Durable & Stable Operation in Harsh Conditions

The pump body is made of high-strength cast iron, the stator can be selected with wear-resistant rubber or corrosion-resistant FEP lining, and the rotor is equipped with stainless steel coating. It can withstand high pressure and strong corrosion conditions and extend the service life of the equipment.

4.Flexible Multi-Industry Adaptation, Meeting Customization Needs

It supports flow and pressure customization, and parameters can be adjusted according to the transfer requirements of different industries, adapting to diversified scenarios such as food-grade sanitary transfer, chemical medium transfer and oil heavy oil transfer.

The stator materials is rubber. Because it needs to form a closed meshing cavity with the rotor, it is an interference fit with the rotor. When the rotor (main shaft) rotates and causes continuous friction, it will wear naturally.

The Progressive cavity pump rotor (also known as the main shaft) is mostly made of stainless steel, and can be selectively plated with chrome;

Due to its meshing relationship with the characteristic geometry of the stator, in addition to natural wear, it is also whether the conveyed medium contains solid particles and corrosive.

The rotor materials include: 304 stainless steel, 316L stainless steel, and 2cr13 stainless steel.

The stator materials include:NBR,EPDM,FKM,HNBR

100% compatible with the original ,Made in China,quality guarantee,high performance cost ratio
