AKAY WATERFLO WF SERIES
Akay WATERFLO WF Series range fully complies to both performance and dimensional standards to the international Standard DIN 24255
Stuffing BoxStandard stuffing box includes gland packing with a lantern ring incorporating high pressure internal flushing. External flush can be fitted and pump can be supplied with a mechanical seal. Conversion from packed box to mechanical seal and back to packing is easy. All pumps that can operate at 2 pole speed have a close tolerance stuffing box bush fitted.
Bearing housingRugged iron construction with only three bearing housings covering complete range of pumps which gives many common inter changeable parts.
BearingsBearings on 33 sizes are grease lubricated sealed for life. 4 sizes have oil lubricated bearings and for this arrangement the housing includes an oil level sight glass and vent.
Support FootEach pump has a remove-able support foot fitted at drive and for greater rigidity.
Shaft SleeveFully mechanical hook type shaft sleeve prevents shaft damage under the gland pac-king which substantially reduces maintenance costs.
Wear RingsReplaceable wear-rings are fitted as standard to all casings and also to back covers on lager pumps which reduces maintenance time and costs.

CasingThe cast iron volute casing is of robust design with integrally cast feed, vertical top centreline discharge with axial suction incorporating cast inlet vane to give best flow to impeller eye.
ImpellerDouble shrouded type is hydraulically balanced and positively driven by shaft key and axially locked sleeve and impeller nut.
ShaftA domed type locking nut seals the stainless steel shaft at the impeller. Only 4 shafts are required to cover whole 37 sizes and reduces inventory to a minimum.
Back pull out featureThis design feature allows the complete rotating element to be removed for servi-cing without disconnecting pipework. If a spacer coupling is fitted than motor does not have to be moved. On re-assembly of pump coupling re-alignment problems are completely eliminated.
