SIHIpr/me- Side Channel Pumps Self-priming, segmental type TECHICAL DATA Delivery head: Casing pressure: Shaft sealing: Flange connections: max. 180 °C for high temperature design (higher temperatures on request) mechanical seal (when seen from the drive end) Protection classification: The Sterling SIHI AEH-X pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a The AEH-X pumps, as per DIN EN 734, are used for problem-free pumping of clean liquids at unfavourable suction side conditions. (condensates, corrosive liquids, ...). Different material possibilities with uniform dimensions and performance characteristics as well as the standard exchangeable components are used for the construction. The AEH-X pumps are particularly recommendable in a wide application range in many • Chemical industry, • Petro-Chemical industry, • Pharmaceutical industry, • Food industry, The pumps of the SIHIp"me range are side channel pumps having segmental type construction. The program comprises, currently, 3 sizes each with 1-8 stages. The existing material design allows an optimum rating for the respectively desired performance range and the pumping medium. The applied hydraulic components are from our modular side channel system (interchangeability of parts). Casing pressure Pressure stages for temperature as per DIN EN 1333. Please observe Technical rules and safety regulations: Casing pressure = inlet pressure + delivery head at minimum pump Suction and discharge branch point radially upwards. Flanges in accordance with DIN EN 1092-2 / PN 40. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. Either by a ball bearing and a liquid surrounded sleeve bearing (design A) or by two ball bearings (design B). The ball bearings are according to DIN 625 and greased for life. Rotation direction Clockwise, when looking at the pump from the drive end. Shaft sealing The shaft is sealed by a mechanical seal according to DIN EN 12756, with quench connection. The shaft sealing is also available in a design suitable for heating or cooling of the mechanical seal and a double mechanical seal (back- to-back as well as tandem) design is possible on request.

Operating principle The AEH-X pump is a side channel system, self priming, and segmental type. A side channel stage consists of: • A suction intermediate part (1 ), • A discharge intermediate part including the side • A vane wheel impeller located between the 2 The fluid entrance goes through the suction hole (4). The turning of the vane wheel impeller creates an under pressure at the beginning of the side channel and the liquid (with or without gas) is drawn in. The pressure generating is obtained by the repetitive re-entering of the liquid in the side channel (5). The liquid goes then to...
