Radial shaft sealing ring - Import export

Pre-assembled pump kit for 99,98 % drum emptying. Due to integrated backflow stop less than 0.05 l residual amount in 200 l drum possible. For pumping thin media out of 200 l drums (immersion length 1000 mm) or IBCs (mmersion length 1200 mm). Comprising drum pump F 425 with mechanical seal, outer tube in stainless steel, commutator motor F 460, hose, hand nozzle and compression gland. Can also be used in hazardous areas. Product attributes: - Pump with mechanical seal - Switch lever to close the backflow valve / foot valve - Pulsation-free transfer - Transfer against closed valve (e.g. hand nozzle) possible - Radial shaft sealing ring prevents intrusion of vapours and liquids into the coupling area Benefits: - Less than 0.05 l residual amount left in 200 l drum - Universally and flexibly applicable - Reduction of cleaning and waste disposal costs - Optimal use of fluids - No loss of medium when taking the pump from drum to drum

Applications at high speed and low pressure. With O‑ring as secondary seal for sealing in the groove base. Hygienic design without undercuts. No sump formation in front of the seal. Reduced heat buildup due to special lip design. Pressureactivated seal energization. The integrated wedge prevents the sealing lip turning inside out. Very long seal life due to high abrasion resistance. Material only generates low frictional force. Sealing lip does not stick to the mating surface even after prolonged shutdown

With internally protected sealing lip. With O‑ring for sealing in the groove base. For high peripheral speed and increased chemical resistance

Types RWDR‑A, RWDRAS, RWDR‑B, RWDRBS, RWDR‑C, RWDRCS

High pressures at relatively low speed. For fluids over a wide viscosity range and for gases. Rotary unions at high pressure. Robot axes

Types 231 to 238 are used for lubricating fluids and to a limited degree also for dry running and purely rotary or oscillating motion. They are only partly suitable for helical motion.

Motor shafts. Gear and frive unit shafts. Fan shafts. Clamping tools. Applications at high speed and lo pressure.
