3 PUMP DESCRIPTION

3.1 Configuration
The PHL type pump is a heavy duty, single stage,
horizontal centrifugal pump, designed for the
Petrochemical Industry, chemical plants, general
service and circulating applications.

3.2 Name nomenclature

The pump size will be engraved on the nameplate
typically as below:
Configuration – see 3.1 above.
Max. impeller size (cm)
Nominal suction branch size (cm)
Nominal discharge branch size (cm)
Specific hydraulic design
The typical nomenclature above is the general guide
to the PHL configuration description. Identify the actual
pump size and serial number from the pump
nameplate. Check that this agrees with the applicable
certification provided.

3.3 Design of major parts

3.3.1 Pump casing
The pump has its main casing gasket axial to the shaft
allowing maintenance to the rotating element by
removing the back pull out unit. Suction and discharge
branches are at the casing and therefore its piping
remain undisturbed at maintenance.
3.3.2 Impeller
The impeller is fully shrouded and is fitted with
impeller wear rings.
3.3.3 Diffuser
The diffuser is tuned to the impeller and the multi
channel diffuser is concentric aligned around the
impeller
3.3.4 Pump Shaft
The pump is of the dry shaft design and has a keyed
drive end.
