Side channel pumps Self-priming, segmental type AOH Sizes 1101 … 3603 Technical data Capacity: Delivery head: Speed: Temperature: Casing pressure: Shaft sealing: Flange connection: Direction of rotation: max. 7.5 m³/h max. 98 m max. 1800 1/min max. 120 °C PN 10 Stuffing box British standard pipe thread (BSP) in counter flanges Clockwise (When seen form the drive end) The SIHI AOH pump is a self-priming side channel pump capable of handling gas along with the medium and operates at a low noise level. The AOH is used when clear or turbid liquids without any abrasive particles are to be handled reliably and trouble-free. Casing pressure Maximum 10 bar from 0 °C up to + 120 °C The performance curve steepness admits a precise regulation of the pressure with a small change in capacity. The AOH is used in domestic plants and agriculture for: Irrigation Drainage Sprinkling Please observe Technical rules and safety regulations. Casing pressure = inlet pressure + delivery head at minimum pump capacity Position of branches Suction and delivery branch point radially upwards. The AOH is well known in domestic plants and agriculture for: Boosting pressure Cooling water Water circulation Boiler feeding Condensate Cleaning plants Ship yards Flanges The oval flanges correspond to SIHI standard PN 10. Counter flanges are provided with female pipe thread. They are supplied together with the pump including joints, screws and nuts. Direction of rotation Clockwise, when looking at the pump from the drive end. Anti-clockwise is possible. Pumps of the series AOH have a segmental type construction with open vane wheel impellers. The program comprises 4 sizes with up to 4 stages for the sizes 1100/1200 and up to 3 stages for the sizes 3100/3600. The performance curves of the AOH are identical for all material designs. Bearing One grease lubricated ball bearing according to DIN 625 and one liquid surrounded sleeve bearing (design A). The first grease filling is done in the factory. Shaft sealing The shaft is sealed by a stuffing box. Mechanical seal design upon request. The applied hydraulic components are from our Modular Side Channel system (interchangeability of parts).
