Material selection
We provide a wide range of materials to choose, these materials can ensure high quality performance and wear and corrosion resistance. MAH uses 27% Chrome resistant material, which has excellent wear resistance to composite medium containing solid particles. The MAHR series adopts natural rubber lining and have good corrosion resistance, they can handle the abrasive fluid whose Ph is 1 to 12 and temperature is 80 degrees Celsius below.
Product features
1. Multi stage series technology for the combination of pumps can be used to meet long distance transportation requirements.
2. The overflow parts have many materials to choose.
3. MAH horizontal centrifugal slurry pump adopts a Variety of speed and driving methods to make the pump run under the best operating conditions.
4. The pump is made of high performance materials and has the advantages of wear resistance and corrosion resistance. It can work in a variety of poor transportation conditions and can treat slurry whose Ph is 1 to 12 and temperature is 80 degrees Celsius below.
5. Drive arrangements: CV drive, ZV drive and parallel drive.
The most common driving devices are parallel drives and CV drives. The installation of CV drive is usually the most economical, and the motor is lifted from the floor, so the maintenance can be greatly simplified.
The impeller diameter of slurry pump cannot be easily changed, so the change of performance needs to be achieved through the change of speed.
Through the V belt drive configuration, you can change one or two pulleys to operate to get close to the required working point, which makes the pump speed changes.
When the pump speed is too low or the power is too high, the V belt is not appropriate. In these cases, it uses a gear box or a gear (gear toothed) belt. Gear belt drives are becoming more and more popular because they have V belt driven dynamic flexibility while having lower tension.
