Application

nnnn

The Sterling SI HI AEH pump is a self-priming side channel

nnnn

pump capable of handling gas along with the medium. The

nnnn

AEH is a Side Channel pump as per DIN EN 734 and operates

nnnn

at a low noise level.

nnnn

The AEH pumps were especially developed for difficult

nnnn

applications in all industry sectors and are thus applied when

nnnn

pure, turbid or aggressive media have to be pumped under

nnnn

difficult conditions without any problems.

nnnn

The different material possibilities with uniform dimensions

nnnn

and performance characteristics as well as the standard

nnnn

exchangeable components, make the AEH particularly

nnnn

recommendable as universal pump for all possible pumping

nnnn

problems. This results in a wide application range in many

nnnn

sectors such as;

nnnn

Chemical industry,

nnnn

Petro-Chemical industry,

nnnn

Pharmaceutical industry,

nnnn

OEM,

nnnn

Oil industry,

nnnn

Food industry.

nnnn

Design

nnnn

Pumps of the series AEH have a segmental type construction

nnnn

with open vane wheel impellers. The pumps is available in a

nnnn

normal industrial design with one liquid surrounded slide

nnnn

bearing and one ball bearing or in a heavy-duty construction

nnnn

with a double ball bearing design.

nnnn

The program comprises 6 sizes each with 1-8 stages. The

nnnn

existing material design allows an optimum rating for the

nnnn

respectively desired performance range and the pumping

nnnn

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

nnnn

pump capacity.

nnnn

Position of branches

nnnn

Suction and discharge branch point radially upwards.

nnnn

Flanges

nnnn

The flanges correspond to DIN EN 1092-2 / PN 40.

nnnn

Flange design as per DIN 2512 with groove or drilled

nnnn

according to ANSI 150 or 300 lbs is basically possible.

nnnn

Bearing

nnnn

Either by a ball bearing and a liquid surrounded sleeve

nnnn

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

nnnn

ball bearings are according to DIN 625 and greased for life.

nnnn

Direction of rotation

nnnn

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

nnnn

Anti-clockwise is possible.

nnnn

Shaft sealing

nnnn

The shaft can be sealed by a stuffing box or a mechanical

nnnn

seal conform DIN EN 12756.

nnnn

The shaft sealing is also available in a design suitable for

nnnn

heating or cooling of the stuffing box or the mechanical seal.

nnnn

Double mechanical seal (back-to-back as well as tandem)

nnnn

or a quench design with throttle bush are available upon

nnnn

request.

nnnn

The AEH can also be supplied with a magnetic coupling (for

nnnn

information see the separate catalogue).
