Abrasive Mechanical Seal x

Conventional chemical stripping processes, very common in steel and metal, in most cases with the use of hydrochloric acid as a pickling agent, They are a critical point for the companies that use them.
The reactions that occur during the process result in the formation of chlorides (ferric and ferrous, in the case of carbon steel), and solid particulate, iron oxide (carepa), that emerges from the plates, wires or rods by the effect of acid attack. This acid mixture + chlorides + mill scale is extremely corrosive and abrasive also.
In these situations the mechanical seal is the component most "sacrificed" the pump and, for its high purchase price or repair, It is an important part in the drive maintenance costs.

In order to provide customers with dedicated pumps stripping processes, minimizing downtime for maintenance, a PH BOMBAS developed mechanical seal Model L, with the following characteristics:

• Lanes on Silicon Carbide, for maximum resistance to abrasion and corrosion conditions.
• No metal parts in contact with the pumped liquid.
• Possibility of continuous or intermittent cleaning of the external springs, preventing fouling by crystallization.
• affordable cost.

  A PH BOMBAS It offers L Model label as a component of the pumps of the series BCNH, BCH e CFRA, which, in its turn, also they are made of materials resistant to the conditions of the etching processes, designed with internal recirculation system which maintains the temperature lubrication and seal, and always operating at low revs, maximizing its life.
