1 Side channel pumps ADH/CDH AEH TECHNICAL DATA Capacity: Head: Speed: max. 7,2 m³/h max. 400 m max rpm Temperature: max. 120 C Casing pressure: Shaft sealing: PN 25 for ADH/CDH PN 40 for AEH stuffing box or standard mechanical seal Flange connection sizes: DIN 2501 PN 25 and PN 40 Direction of rotation: clockwise when looking at the pump from the drive end APPLICATION Sterling SIHI side channel pumps - are self priming - can handle gas during normal liquid duty - are of noiseless operation The pumps of the ADH/AEH series are used when liquids and condensates without abrasive admixtures are to be handled trouble-free under high heads. The pumps of series CDH with NPSH-improving inducer stage are used when liquids are to be handled reliably and trouble-free under critical suction conditions. With these machines, a safe and efficient pumping service can be achieved, even if the net positive suction head available is low With regard to hydraulic design they have been staged as is customary in boiler construction. The pumps are used: in industries running boilers for the handling of condensate and boiler feed water for the construction of washing, cleaning and spraying plants in the construction of fire-extinguishing equipment BAUART The pumps of the ADH/AEH series are segmental type, horizontal side channel pumps self-priming and handling gases during normal liquid duty, operating with unshrouded vane wheel impellers. The pumps of the CDH series are horizontal, self-priming, segmental type, side channel pump, handling entrained gases, equipped with unshrouded impellers and a suction side centrifugal stage combination system) for attaining superior characteristics with respect to net positive suction head (NPSH). By pumps of the ADH/CDH/AEH series are side channel pumps of the high-speed type - maximum 3000 rpm - that have been designed with special regard to noiseless running. The steeply sloped curves offer considerable possibilities of pressure-dependent regulation. CONSTRUCTION Casing pressure: Max. 25 bar from 0 C to C (ADH/CDH) Max. 40 bar from 0 C to C (AEH) Please note: Casing pressure = inlet pressure + discharge head at min. flow rate Position of branches: Suction and discharge branches showing radially upwards. Flanges: The flanges comply with: DIN 2534 PN 25 (ADH/CDH) DIN 2535 PN 40 (AEH) Flanges drilled according to ANSI 150/300 can be supplied. Bearings: One grease-lubricated deep-groove ball bearing according to DIN 625. The first filling with grease is made in the factory. One sleeve bearing flushed by the liquid handled. Designation of this construction type: A. Direction of rotation: Clockwise when looking at the pump from the drive end. Designation of this construction type:. N Shaft sealing: The sealing of the shaft passage, according to choice, can be effected by a stuffing box or by standard mechanical seal. Designation 081: uncooled stuffing box with lantern ring and internal flushing. Temperature range: 0 C to 120 C Designation 135: Standard single-action mechanical seal, uncooled, unbalanced, with internal flushing Temperature range: 0 C to 105 C PUMP TECHNOLOGY ADH/CDH PII/ E 02/
