SIHIprime - Side Channel Pumps Self-priming, segmental type TECHICAL DATA Capacity: Delivery head: max. 120 °C (higher temperatures on request) Casing pressure: Shaft sealing: mechanical seal or stuffing box Flange connections: clockwise (when seen from the drive end) Protection classification: The Sterling SIHI AKH-X pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. The AKH-X pumps are used for problem-free pumping of clean liquids at unfavourable suction side conditions. Their Head-Flow curves are allowing an accurate pressure regulation for a small flow variation. Different material possibilities with uniform dimensions and performance characteristics as well as the standard exchangeable components are used for the construction. The AKH-X pumps are particularly recommendable in a wide application range in many sectors such as: Chemical industry, Petro-Chemical industry, Oil industry, Machines and automotive industries, Food industry, Building construction, Plastic and rubber industry, Surface treatment, Shipyards Casing pressure Maximum 25 bar from -40 °C up to +120 °C. Please observe Technical rules and safety regulations: Casing pressure = inlet pressure + delivery head at minimum pump capacity. Position of branches Suction and discharge branch point radially upwards. Flanges Flanges in accordance with DIN EN 1092-2 / PN 25. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. Bearing 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 The pumps of the SIHI range are side channel pumps having segmental type construction. The program comprises, currently, 3 sizes each with 1-6 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). Clockwise, when looking at the pump from the drive end. Anti-clockwise is possible. Shaft sealing The shaft is sealed by a mechanical seal according to DIN EN 12756 or by stuffing box. PUMP TECHNOLOGY AKH-X PII/3 07/2009

AKH-X Operating principle The AKH-X pump is a Side Channel system, self priming, segmental type. 1 A Side Channel stage consists of: A suction intermediate part (1), A discharge intermediate part including the Side Channel (2), A vane wheel impeller located between the 2 intermediate parts (3). 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...
