Mechanical seal DY47,DY47F

Products Mode: Mechanical seal DY47,DY47F
wave spring mechanical seals: wave spring pump mechanical seals
DY47 series of mechanical seals are designed with wave springs which occupy smaller space than multipe springs,but special tooling must be made to reach the best manufacturing results, besides the tempering required on this design limits materials to the high grade stainless steel and Hastelloy groups.Thirdly, a greater change in loading for a given deflection must be tolerated. A great deal of force loss or force gain with comparatively small axial movement must be expected.

Working Conditions of pump mechanical seals DY47: handling fluids:Water, oil, acid, alkali, ,etc. temperature:-30oC~200oC, pressure: ≤1.2Mpa, speed: ≤ 18m/Sec. carbon,silicon cabide/sic,tungsten carbide/tc/sintered silicon carbide/ssic can work as mechanical seal faces/rings and NBR,FKM and epdm is operating as secondary sealing elements and SUS 304 and 316 can be made into wave springs and other metal parts.
