Side Channel pumps Self-priming, segmental type Technical data Delivery head: Casing pressure: Shaft sealing: Flange connections: max. 180 °C for high temperature design (higher temperatures upon request) stuffing box or mechanical seal (when seen from the drive end) The Sterling SI HI AEH pump is a self-priming side channel pump capable of handling gas along with the medium. The AEH is a Side Channel pump as per DIN EN 734 and operates The AEH pumps were especially developed for difficult applications in all industry sectors and are thus applied when pure, turbid or aggressive media have to be pumped under difficult conditions without any problems. The different material possibilities with uniform dimensions and performance characteristics as well as the standard exchangeable components, make the AEH particularly recommendable as universal pump for all possible pumping problems. This results in a wide application range in many Chemical industry, Petro-Chemical industry, Pharmaceutical industry, Food industry. Pumps of the series AEH have a segmental type construction with open vane wheel impellers. The pumps is available in a normal industrial design with one liquid surrounded slide bearing and one ball bearing or in a heavy-duty construction with a double ball bearing design. The program comprises 6 sizes each with 1-8 stages. The existing material design allows an optimum rating for the respectively desired performance range and the pumping The applied hydraulic components are from our Modular Side Channel system (interchangeability of parts). Casing pressure Pressure stages for temperature as per DIN EN 1333. Please observe Technical rules and safety regulations: Casing pressure = inlet pressure + delivery head at minimum pump capacity. Suction and discharge branch point radially upwards. Flange design as per DIN 2512 with groove or drilled according to ANSI 150 or 300 lbs is basically possible. 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. Clockwise, when looking at the pump from the drive end. Shaft sealing The shaft can be sealed by a stuffing box or a mechanical The shaft sealing is also available in a design suitable for heating or cooling of the stuffing box or the mechanical seal. Double mechanical seal (back-to-back as well as tandem) or a quench design with throttle bush are available upon The AEH can also be supplied with a magnetic coupling (for information see the separate catalogue).
