Pumped Media Seals

The optimum primary seal can be chosen to match the pumped media and duty conditions. Single or double mechanical seals include flushed or aseptic variants. For arduous duties hard faced seal materials such as tungsten carbide or silicon carbide can be used. A wide variety of commercially available mechanical seal options including single and double cartridge seals are available for sludge and other difficult applications. Packed glands offer a simple, low cost, and easy to maintain controlled leakage sealing arrangement. Pumped media wetted elastomers are EPDM, NBR, FPM all FDA conforming or PTFE for chemical applications.

Rotor Materials

For increased abrasion resistance pumps may be supplied with NBR covered (models A7-0550-H07 & A8-0745-H10).

Surface Finish & Coatings

For abrasive applications the pumphead and rotors may be supplied with a tungsten carbide coating or other surface hardening treatment to increase wear resistance.

Increased Pressure Rating

Alternative higher strength shaft materials will enhance pressure ratings.
