Section 2.......................................................................Pump Construction
Heavy duty roller bearings:
This pump is fitted with heavy duty roller bearings running in oil lubricated housing with oil flinger.
Housing is fitted with breather and oil level plug and drain plugs. Available options include:
• Fitting deep groove grease nipple lubricated, regreasable bearings
• Oil coolers
• Labyrinth shaft seals
Positively located dual bearings:
These ISO-Pro Pumps are fitted with positively located dual bearings at motor end and with a roller
bearing at pump end. These bearings are oil lubricated. Available options include:
• Fitting deep groove grease lubricated bearings, either sealed for life or grease nipple lubricated
• Oil coolers
• Labyrinth shaft seals
3.6 Pump Shaft Seals
As a standard, ISO-PRO Pumps are fitted with single, unbalanced, on-shaft mechanical seal.
Other seal options are available but are not limited to:
• Single balanced Mechanical Seal
• Single Balanced cartridge seals
• Double Balanced cartridge seals
• Packed Gland Seals
External clean water flushing and cooling can be supplied for high temperature, abrasive or toxic
applications.
3.7 Driver
The driver is normally an electric motor. Different drive configurations may be fitted such as internal
combustion engines, turbines, hydraulic motors etc driving via couplings, belts, gearboxes etc.
Upon customer request, Southern Cross ISO-PRO pumps maybe supplied
with an empty shaft seal cavity to allow the dealer/customer to fit a seal to suit
a particular application. It is important that the shaft seal is fitted according
to the manufacturer's instructions. In the case of a packed gland, the gland
needs to be adjusted so a slow drip of water is evident when the pump is
operating. A drain hole is provided in the bearing housing (below the seal
cavity) for use with a packed gland.
If the gland in the pump is to be lubricated with water from the pump body,
ensure the plug (A) is fitted and the passage from the pump body to the seal
cavity is clear. If the pump gland is to be lubricated from an external water
supply, plug (B) must be fitted. Ensure passage from seal cavity to external
water supply is clear before connecting water supply line.
