APPLICATION

nnnn

The Sterling SIHI AEH-X pump is a self-priming side channel pump

nnnn

capable of handling gas along with the medium and operates at a

nnnn

low noise level.

nnnn

The AEH-X pumps, as per DIN EN 734, are used for problem-free

nnnn

pumping of clean liquids at unfavourable suction side conditions.

nnnn

(condensates, corrosive liquids, ...).

nnnn

Different material possibilities with uniform dimensions and

nnnn

performance characteristics as well as the standard exchangeable

nnnn

components are used for the construction. The AEH-X pumps are

nnnn

particularly recommendable in a wide application range in many

nnnn

sectors such as:

nnnn

• Chemical industry,

nnnn

• Petro-Chemical industry,

nnnn

• Pharmaceutical industry,

nnnn

• Oil industry,

nnnn

• Food industry,

nnnn

. OEM.

nnnn

DESIGN

nnnn

The pumps of the SIHIp"me range are side channel pumps having

nnnn

segmental type construction.

nnnn

The program comprises, currently, 3 sizes each with 1-8 stages.

nnnn

The existing material design allows an optimum rating for the

nnnn

respectively desired performance range and the pumping medium.

nnnn

The applied hydraulic components are from our modular side

nnnn

channel system (interchangeability of parts).

nnnn

CONSTRUCTION

nnnn

Casing pressure

nnnn

Maximum 40 bar from - 40 °C up to +120 °C.

nnnn

Maximum 32 bar from +120 °C up to +180 °C.

nnnn

Pressure stages for temperature as per DIN EN 1333.

nnnn

Please observe

nnnn

Technical rules and safety regulations:

nnnn

Casing pressure = inlet pressure + delivery head at minimum pump

nnnn

capacity.

nnnn

Position of branches

nnnn

Suction and discharge branch point radially upwards.

nnnn

Flanges

nnnn

Flanges in accordance with DIN EN 1092-2 / PN 40.

nnnn

Flange design as per DIN 2512 with groove or drilled according to

nnnn

ANSI 150 or 300 lbs is basically possible.

nnnn

Bearing

nnnn

Either by a ball bearing and a liquid surrounded sleeve bearing

nnnn

(design A) or by two ball bearings (design B). The ball bearings are

nnnn

according to DIN 625 and greased for life.

nnnn

Rotation direction

nnnn

Clockwise, when looking at the pump from the drive end.

nnnn

Anti-clockwise is possible.

nnnn

Shaft sealing

nnnn

The shaft is sealed by a mechanical seal according to DIN EN

nnnn

12756, with quench connection.

nnnn

The shaft sealing is also available in a design suitable for heating or

nnnn

cooling of the mechanical seal and a double mechanical seal (back-

nnnn

to-back as well as tandem) design is possible on request.
