Sewage sludge rotary pump-Qinping Machinery (Shanghai) Co., Ltd

Qinping rubber rotor pump is a non-contact volumetric pump with advantages such as low speed, strong self suction, high efficiency, wear resistance, and forward and reverse rotation. It is particularly suitable for conveying high viscosity, high solid content, and particulate media. According to the medium selection, the material of the rubber rotor includes fluororubber, nitrile rubber, EPDM, and chloroprene rubber. Especially in the fields of environmental protection and sewage treatment, it has broad application prospects.

Advantages Overview:
The Qin Ping rotor pump series is complete and accurately matches customer needs.
A regular and spacious entrance allows viscous or solid particle containing media to pass smoothly. The medium runs for a short distance within the pump body, causing minimal shear and pulsation of the medium, resulting in smooth transportation. Even if it contains fibers or strip-shaped objects, blockage will not occur.
Provide full lining protection on all four sides inside the pump, with only the pump casing, rotor, shaft seal in contact with the conveying medium. The other parts of the pump (including the shaft) are completely out of contact with the medium, and any wear and tear can be repaired by replacing the lining plate.
Compact structure, small space occupation, and multiple installation methods can be used in limited site conditions.
The quick opening design of the pump cover and the single-sided bearing support design of the rotor enable online maintenance of the pump (i.e., replacement of accessories and maintenance do not require disassembly of the pump or pipeline).

Application scope:
→ Sewage treatment plant sludge, residual sludge, reflux sludge, sludge feed, papermaking sludge, fecal wastewater, water oil mixture.
Ship sewage, leakage liquid, waste oil, mine sludge, cement slurry, lime slurry, flotation liquid.
Finished oil unloading, gasoline and diesel, heavy oil sludge, methanol, ethanol.

Comparison between Qinping rotor pump and gear pump:
1. Good airtightness, strong self suction ability, with a self suction height of 9 meters and a maximum working pressure difference of 1.2 Mpa.
2. The spiral cam rotor body covered with elastic rubber has high efficiency, corrosion resistance, low pulsation, forward and reverse rotation, and can rotate dry (idle).
3. Transporting high viscosity and solid particle containing media, it is non clogging, has good performance, and the particle throughput can reach up to 85MM.
4. The rotor cavity and rotor profile curve are relatively smooth, with large space, no dead corners, and easy to clean.
5. A cam pump is a low shear rotor pump that acts gently on the fluid medium without rigid shear compression. For fluids containing corrosive particles, only the lining plates around the pump need to be replaced.
