Application The Sterling SIHI ADHL/AEHL and CDHL pumps are selfpriming side channel pumps capable of handling gas along with the medium and operates at a low noise level. The ADHL/AEHL series are used to handle clear or turbid liquids, under high heads and without any abrasive particles, reliably and trouble-free. The CDHL with NPSH-improving inducer stage are used when liquids under critical suction conditions have to be handled reliably and trouble-free. With these pumps a safe and efficient pumping service can be achieved even if the net positive suction head available is low. The number of hydraulic stages are as is customary in the boiler industry. The performance curve steepness admits a precise regulation of the pressure with a small change in capacity. The pumps are used in; • Boiler industry for condensate and boiler feed water handling, • Washing, cleaning and spraying plants, • Dry cleaning. Design The pumps of the ADHL/AEHL and the CDHL series have a segmental construction with open vane wheel impellers. The CDHL pumps (combination pumps) are equipped with open impellers as well as a suction side centrifugal stage for attaining superior characteristics with respect to the Net Positive Suction Head (NPSH). The pumps of the ADHL/CDHL/AEHL series are side channel pumps of the high-speed type that have been designed with special regard to noiseless running. The program comprises 6 sizes. Construction Casing pressure Maximum 25 bar from 0 °C up to +120 °C for ADHL/CDHL Maximum 40 bar from 0 °C up to +120 °C for AEHL 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 The flanges correspond to DIN EN 1092-2, PN 25 for ADHL/ CDHL and PN 40 for AEHL. Flanges drilled according to ANSI 150 or 300 lbs are basically possible. 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. Direction of rotation Clockwise, when looking at the pump from the drive end. Shaft sealing The shaft can be sealed by a stuffing box or a standard mechanical seal. Technical data Capacity: from 0,3 up to 7,2 m³/h Head: from 20 up to 400 m Speed: 2900 rpm (max. 3400 rpm for ADH 0800/0900) Temperature: max. 120 °C Casing pressure: PN 25 for ADHL/CDHL PN 40 for AEHL Shaft sealing: stuffing box or standard mechanical seal Flange connections: DIN 2501 / PN 25 and PN 40 Direction of rotation: clockwise (when seen from the drive end) Side Channel pumps Self-priming, segmental type ADHL/CDHL 0801 ... 2504 AEHL 0805 ... 0808 Sterling Fluid Systems Pumping Technology ADHL/CDHL/AEHL-00 / 2003
