APPLICATION
The Sterling SIHI AKH-X 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-X pumps are used for problem-free pumping of clean
liquids at unfavourable suction side conditions.
Their Head-Flow curves are allowing an accurate pressure
regulation for a small flow variation.
Different material possibilities with uniform dimensions and
performance characteristics as well as the standard exchangeable
components are used for the construction. The AKH-X pumps are
particularly recommendable in a wide application range in many
sectors such as:
č Chemical industry,
č Petro-Chemical industry,
č Oil industry,
č Machines and automotive industries,
č Food industry,
č Building construction,
č Plastic and rubber industry,
č Surface treatment,
č Shipyards
DESIGN
The pumps of the SIHIprime range are side channel pumps having
segmental type construction.
The program comprises, currently, 3 sizes each with 1-6 stages.
The existing material design allows an optimum rating for the
respectively desired performance range and the pumping medium.
The applied hydraulic components are from our modular Side
Channel system (interchangeability of parts).
CONSTRUCTION
Casing pressure
Maximum 25 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
Flanges in accordance with DIN EN 1092-2 / PN 25.
Flange design as per DIN 2512 with groove or drilled according to
ANSI 150 or 300 lbs is basically possible.
Bearing
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.
Rotation direction
Clockwise, when looking at the pump from the drive end.
Anti-clockwise is possible.
Shaft sealing
The shaft is sealed by a mechanical seal according to DIN EN
12756 or by stuffing box.
