Mechanical seals for Pedrollo pumps
Mechanical seal for Pedrollo pump
The design of the mechanical seal consists mainly of two parts: a movable part and a fixed part. The fixed part is usually a ring that is fixed in the pump housing. The movable part is mounted on the shaft and is pressed against the fixed part by means of a spring. Mechanical sealing is achieved using secondary seals (bellows, rubber rings) and a friction pair. When choosing a mechanical seal, it is important to choose the material of the secondary seals and friction pairs.
Pedrollo Mechanical Shaft Seal Materials
rubber material:
- NBR (nitrile butadiene rubber), temperature resistance -20 to +120C
- EPDM (ethylene-propylene rubber), temperature resistance -30 to +170C
- Viton (fluoroelastomer), temperature resistance -30 to +185C
- PTFE (fluoroplast), temperature resistance -260 to +260C
Friction pairs
- SUS - metal (stainless steel)
- CAR - graphite
- CER - ceramics
- SIC - silicon carbide
- TC - tungsten carbide
It is visually difficult to understand how these materials differ from each other (except for PTFE), so it is easier to choose a material based on the pumped medium and its temperature. Please contact us, we will help you determine the material and choose the mechanical seal you need for the Pedrollo pump.
In PEDROLLO pumps (Pedrolo), mechanical seals with a conical spring R-BT-FN and R-BT-AR are mainly installed. In order to buy a mechanical seal for PEDROLLO, you need to know the type designation "AR-12" or the pump part number. We select seals according to the sample, according to the PEDROLLO pump article or according to the markings of Burgmann, Roten, AESSEAL and other seal manufacturers.
