LPG – Side channel pumps For handling gas along with the medium SC Sizes 2001 … 2004 Technical data Capacity: Differential pressure: Speed: Temperature: Casing pressure: Shaft sealing: Flange connections: Direction of rotation: max. 65 l/min max. 14.5 bar max. 2900 1/min max. 80 °C PN 25 Mechanical seal DIN 2501 / PN 25 Anti-clockwise (when viewed form the drive end) The SIHI SC 2000 pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. Casing pressure Maximum 25 bar from - 25 °C up to + 80 °C The SC 2000 is, due to its special design, very suitable for problem-free pumping of clean liquids at unfavourable suction side conditions. The SC 2000 can also be used for NPSHA of 0.4 – 0.65 m. Please observe Technical rules and safety regulations. Casing pressure = inlet pressure + delivery head at minimum pump capacity The SC 2000 is especially developed for: LPG-plants for the pumping of propane / butane Bottom off-loading Position of branches Axial suction branch, discharge branch points radially upwards. Flanges The flanges correspond to DIN EN 1092-2 / PN 25. Design Pumps of the series SC have a segmental type construction with open vane wheel impellers. The construction of the SC pump is a so-called centrifugal combined system. This combination pump is suited with a centrifugal stage in serial connection before the side channel stages to obtain a more favourable NPSH. The SC 2000 pump has 1 - 4 stages and is available in cast iron EN-GJL-250 or Nodular iron EN-GJS-400-18-LT. The applied hydraulic components are from our Modular Side Channel system (interchangeability of parts). Bearing One grease lubricated ball bearing according to DIN 625 and one liquid surrounded sleeve bearing (design A). The ball bearing is greased for life Direction of rotation Anti-clockwise, when looking form the drive end. Shaft sealing The shaft is sealed with a mechanical seal suitable for LPG. Casing seal The casing is sealed by paper ring. Drive By electrical motor, type of construction IM B3, explosion proof.
