Side Channel Pumps Series AKH, 35 m³/h, 144 m, 120 °C - 1

Side Channel Pumps Self-priming, segmental type AKH 1101 … 6103 Technical data Capacity: Casing pressure: Shaft sealing: stuffing box or mechanical seal Flange connections: clockwise (when seen from the drive end) The Sterling SIHI AKH 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 is suitable for trouble free handling of clean or turbid liquids without any abrasive particles. Casing pressure The performance curve steepness admits a precise regulation of the pressure with a small change in capacity. The AKH pump has been developed for a broad range of medium duty applications in: • Chemical industry, • Petro-Chemical industry, • Oil industry, • Machinery and automobile industry , • Food industry, • Building trades, • Plastic and rubber industry, • Surface treatment, • Ship yards. Maximum 16 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 The flanges correspond to DIN EN 1092-2 / PN 16. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. Design Pumps of the series AKH have a segmental type construction with open vane wheel impellers. The pump construction is either with one liquid surrounded slide bearing and one ball bearing or in a more industrial construction by using a double ball bearing design. The program comprises 6 sizes with up to 4 stages (an extension with 5 or 6 stages is possible for certain sizes). The performance curves of the AKH are identical for all the material designs. The applied hydraulic components are from our Modular Side Channel system (interchangeability of parts). Either by one grease lubricated ball bearing and one liquid surrouned sleeve bearing (design A) or by two grease lubricated ball bearings (design B). The ball bearings are according to DIN 625. The first grease filling is done in the factory. Direction of rotation Clockwise, when looking at the pump from the drive end. Anti-clockwise is possible. Shaft sealing The shaft can be sealed by either a stuffing box or a standard mechanical seal. Sterling Fluid Systems Pumping Technology AKH-00 2003
