Waterflo WF AKAY INDUSTRIES AKAY WATERFLO WF SERIES Akay WATERFLO WF Series range fully complies to both performance and dimensional standards to the international Standard DIN 24255 Stuffing Box Standard 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 housing Rugged iron construction with only three bearing housings covering complete range of pumps which gives many common inter changeable parts. 08 bearings and for this arrangement the housing includes an oil level sight glass and Bearings Bearings on sizes are grease lubricated sealed for life. 4 sizes have oil lubricated vent. Support Foot Each pump has a remove-able support foot fitted at drive and for greater rigidity. Shaft Sleeve Fully mechanical hook type shaft sleeve prevents shaft damage under the gland packing which substantially reduces maintenance costs. Wear Rings Replaceable wear-rings are fitted as standard to all casings and also to back covers on lager pumps which reduces maintenance time and costs.
Waterflo WF AKAY INDUSTRIES Casing The 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. Impeller Double shrouded type is hydraulically balanced and positively driven by shaft key and axially locked sleeve and impeller nut. Shaft A domed type locking nut seals the stainless steel shaft at the impeller. Only 4 shafts are required to cover whole 7 sizes and reduces inventory to a minimum. 08 Back pull out feature This design feature allows the complete rotating element to be removed for servicing 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.
