D 65328 10 2000-08 L entrifugal ump pplication he L pump is a highly efficient and economical centrifugal pump, which meets the requirements of sanitary and gentle product treatment and chemical resistance. L is available in twelve sizes, L-5, -10, -15, -20, -25, -35, -40, -45, -50, -60, -70 and -80. tandard design he L pump consists of a standard motor, stub shaft, mechanical compression coupling (L-5 with pin bolts), adaptor, back plate, impeller, pump casing and shaft seal. (L-5 has clamp connection between pump casing and back plate). he L pump is designed for I with emphasis on large internal roundings and cleanable seals. he sanitary version of L has a stainless steel shroud for protection of the motor, and the complete unit is supported on four adjustable stainless steel legs. he industrial version of L has no shroud. haft seals he L pump is equipped with either an external single or a flushed shaft seal. oth have stationary seal rings in acid-resistant steel II 329 with sealing surface in silicon carbide and rotating seal rings in carbon. he secondary seal of the flushed seal is a long lasting lip seal. he pump may also be equipped with a double mechanical shaft seal. Materials roduct wetted steel parts: cid-resistant steel II 316L.
