Application

Construction

The SIHI AOH pump is a self-priming side channel pump
capable of handling gas along with the medium and
operates at a low noise level. The AOH is used when clear
or turbid liquids without any abrasive particles are to be
handled reliably and trouble-free.

Casing pressure
Maximum 10 bar from 0 °C up to + 120 °C

The performance curve steepness admits a precise
regulation of the pressure with a small change in capacity.
The AOH is used in domestic plants and agriculture for:
Irrigation
Drainage
Sprinkling

Please observe
Technical rules and safety regulations.
Casing pressure = inlet pressure + delivery head at
minimum pump capacity

Position of branches
Suction and delivery branch point radially upwards.

The AOH is well known in domestic plants and agriculture
for:
Boosting pressure
Cooling water
Water circulation
Boiler feeding
Condensate
Cleaning plants
Ship yards

Flanges
The oval flanges correspond to SIHI standard PN 10.
Counter flanges are provided with female pipe thread. They
are supplied together with the pump including joints, screws
and nuts.

Design

Direction of rotation
Clockwise, when looking at the pump from the drive end.
Anti-clockwise is possible.

Pumps of the series AOH have a segmental type
construction with open vane wheel impellers.
The program comprises 4 sizes with up to 4 stages for the
sizes 1100/1200 and up to 3 stages for the sizes
3100/3600. The performance curves of the AOH are
identical for all material designs.

Bearing
One grease lubricated ball bearing according to DIN 625
and one liquid surrounded sleeve bearing (design A). The
first grease filling is done in the factory.

Shaft sealing
The shaft is sealed by a stuffing box.
Mechanical seal design upon request.

The applied hydraulic components are from our Modular
Side Channel system (interchangeability of parts).
