QWP all stainless steel submersible sewage pump

QWP all stainless steel submersible sewage pumpProduct Overview:

QWP stainless steel submersible sewage pump is a type of submersible sewage pump designed specifically for transporting solid particles, fiber materials, and corrosive media. It is widely used in chemical, petroleum, municipal sewage treatment, construction sites, and other fields.

The pump is made of 304/316 stainless steel material, which has the characteristics of corrosion resistance, wear resistance, and compact structure. It supports continuous operation underwater without the need to build a pump room and is easy to install. Its core advantages include:

Large channel anti clogging design: The impeller adopts a single or double channel structure, which can effectively pass solid particles with a diameter of 50% of the pump diameter and fibers with a diameter of 5 times the diameter.

Double mechanical seal: Adopting double end tungsten carbide mechanical seal, combined with oil-water probe, it can automatically alarm and protect when the seal is damaged and water enters, ensuring the safety of the motor.

Long life operation: It can run continuously for over 8000 hours under reasonable working conditions, suitable for high load operating environments.

Intelligent control support: Optional fully automatic protection control cabinet can be equipped to achieve multiple monitoring of water leakage, electric leakage, overload, overheating, etc., ensuring operational reliability.

Flexible installation: Supports dual rail automatic coupling installation and mobile free installation for easy maintenance and emergency use.

Core technology and process characteristics

In addition to the basic stainless steel material, QWP pumps adopt multiple technologies in internal structure and protective processes to ensure long-term stable operation.

Hydraulic component design: Adopting a unique single blade or double blade impeller structure, the flow channel is wide and can effectively pass through fiber material with a length of 5 times the pump diameter and solid particles with a diameter of 50% of the pump diameter, with significant anti clogging performance. ‌‌‌

Sealing and protection system: The mechanical sealing surface is usually made of alloy to silicon carbide or hard wear-resistant tungsten carbide material. The dual channel series sealing design allows it to operate in the oil chamber for a long time, with a continuous operating life of over 8000 hours. ‌

Motor and insulation technology: The motor windings are mostly made of F-grade insulation materials, and the bearings are selected from imported brands (such as SKF or NSK). Some high-risk scenario models have passed MA safety mark certification or ExdIIBT4 explosion-proof qualification certificate, and are suitable for environments such as coal mines and petrochemicals. ‌‌‌

Intelligent monitoring and protection: The sealed oil chamber is equipped with high-precision anti-interference water leakage detection sensors, and thermal sensitive elements are embedded in the stator winding. Combined with a fully automatic control cabinet, it can achieve multiple protections for water leakage, electric leakage, overload, and overheating. ‌‌‌

Application scenarios and market references

This device plays a key role in fluid transportation in multiple industries due to its corrosion resistance and non clogging characteristics, and its market price is greatly affected by configuration.

Main application areas: Suitable for fields such as chemical, petroleum, pharmaceutical, mining, papermaking, and municipal engineering. Specific scenarios include urban sewage treatment plant drainage systems, construction site slurry discharge, livestock farm wastewater discharge, and rural farmland irrigation. ‌‌

Installation and maintenance: Provide a dual rail automatic coupling installation system, which eliminates the need for personnel to enter the sewage pit during maintenance; Mobile installation is suitable for temporary emergency situations, simply put on a rubber hose and place it underwater to start working. ‌‌

Price reference: The market quotation varies significantly depending on the model, material (304 or 316), and power. The reference price for small models is about 1000 yuan, while the price for large models can reach several thousand yuan to tens of thousands of yuan. The specific price depends on the manufacturer's real-time quotation. ‌‌
