PULERER BACK COVER: Hidden but vital protection in industrial pumps
In many mining and processing industries, there are components that are less visible, but they play a key role in extending the life of the equipment. Polyurethane butterfly or butterfly back cover is one of these components used in centrifugal pumps, especially slice pumps. This piece, also known as PU Wear Plate or Polyurethane Impeller Back Cover, is exclusively produced in the high -quality goldsmith industry.
What is the function of the butterfly in the pump?
Behind the butterfly, as its name implies, is installed behind the pump impeller and has several important tasks to discuss below.
Key Applications Behind Polyurethane Butterfly:
1. Preventing early abrasion of parts: In abrasive environments such as sand, mud, this piece prevents direct particle contact with the pump metal body and prevents severe erosion.
2. Increasing Pump Hydraulic Increase: The back of the polyurethane impeller with its own design reduces the flow turbulence behind the impeller, thereby enhancing the pump productivity.
3. Protecting bearings and mechanical floods: By preventing the penetration of suspended particles into the bearing and mechanical floods, it prevents their early failure and reduces the costs of repair.
4. Reducing the vibration and noise produced: The elasticity of the polyurethane helps absorb vibrations and reduces noise pollution and helps to live longer.
Why polyurethane? Benefits of the PUPP over other materials:
What pumps are used behind the PU impeller?
• Slurious pumps: Suitable for transferring slurry in the mineral, copper, iron and coal concentrate, gold, silica, sand and ... • Sewage pumps: To prevent clogging behind the impeller by suspended materials. • Industrial pumps: In chemical, food, cellulose and paper plants. • Salt water pumps: Due to high resistance to corrosion by saline and acidic water.
Restrictions on the back of polyurethane butterfly: Although the PU is very resistant and flexible, it may decrease performance at very high temperatures (over 80 to 100 degrees Celsius). In these cases, the use of cast iron or cast iron is recommended.
Why the goldsmiths of the goldsmith industry?
In the goldsmith's equipment collection, it is possible to produce different types of butterfly with various materials including cast iron, tires and polyurethane.
