Elite Construction Painting Horizontal, single stage, end suction with vertical Prior to painting, the pump is thoroughly cleaned of scale, discharge, complying with the requirements of EN 733 weld splatter and any other foreign material. The pump is (DIN 24255). Most models are suitable for 1600kPa (16 then painted with a high quality industrial enamel paint. bar) pressure except for larger pumps that are rated for 1000kPa (10 bar). The pull back out design allows for the Accessories maintenance of the pump without disturbing the pipework Drive connected to the casing, or the pump alignment.

3 The pump is only recommended for direct drive via a flexible spacer coupling. Spacer couplings enable the Flanges utilisation of the back pull out feature. Pump flanges have raised faces and are to standards Where belt drives are necessary a separate jack AS/NZS , ISO 16 bar. Gauge tappings are (intermediate) shaft with bearings to carry the belt loads provided on suction and discharge flanges as standard. may be required. Impellers All drive systems, where supplied by KSB Ajax, are The shrouded impellers have front seals and, either back appropriately protected by suitable guards. vanes or rear seals with balance holes to provide hydraulic balance. Impellers are dynamically balanced, are keyed to Baseplate the shaft and are located axially between the sleeve and Baseplates for electric drives are available in a variety of impeller nut.

Bearings Pump Selection For pump selection the hydraulic performance curves Grease Lubrication Standard should be used.

5 These curves are based on water at Oil Lubrication for high speed models (EH). 15oC and SG equal to Max. Pump Temperature 95oC. NPSH values are indicated on the performance curves. The Bearing arrangement consists of two identical single At least should be added as a safety margin. row deep groove ball bearings which are grease lubricated To overcome variations between actual and design through grease nipples located in each bearing cover. system requirements it is recommended that the driver power exceeds the absorbed pump shaft power. Shaft Seal The shaft sealing is carried out by means of mechanical seal with the option of packed gland. Mechanical Seal - A single mechanical seal, with a ceramic stationary face and carbon rotating face is fitted as Absorbed Pump Driver Power standard. The standard seal elastomer is nitrile and is Shaft [kW] Reserve suitable for up to 95oC temperature applications.

6 The other seal components are AISI 304 stainless steel. Up to Approx. 20%. Options: Balanced seal option M1. - 40 Approx. 15%. Cyclone separator option S1. Gland Packing - Fitted with removable lantern ring and Above 40 Approx. 10%. square plaited packing. Packing is fitted over the sleeve to prevent shaft wear. 3.
