MAXIMUM FLOW RATE
- The maximum flow rate is determined by the minimum differential pressure of the pump. The minimum pressure should
never be less than that indicated on the pump label. (Fig.4)
MINIMUM FLOW RATE
- The pump should not work against a closed discharge valve, as this would cause an increase in temperature which could
damage parts of the pump and shorten its useful life.
- The continuous minimum flow rate must be at least 10% of the nominal flow rate indicated on the pump label. (Fig.4).
9. MAINTENANCE
- For regular control:
• Check that the mechanical parts are tightly secured and check the condition of the screws supporting the machine.
• Clean the pre-filter basket regularly to avoid drops in pressure. To prevent the basket from breaking, do not hit it
during the cleaning process.
• The pump should be checked every 100 hours of operation or less, depending on the level of cleanliness of the water.
• Check the temperature of the machine and the electric motor. In the event of a fault, stop the machine immediately and
contact the nearest Technical Assistance Service.
• Check for machine vibrations. In the event of a fault, stop the machine immediately and contact the nearest Technical
Assistance Service.
- Should the pump stop, check that consumption of the running motor in amperes is equal to or below that indicated on
the manufacturer's characteristics plate. If this information is available, contact the nearest Technical Assistance Service.
- Empty the pump if it is to remain at a standstill for a certain length of time, especially in cold countries where there is a
risk of freezing.
- Remove the purge cap to empty the pump.
- Every time the pre-filter is opened, clean the seal and its seating of any impurities to ensure airtightness when the cap
is closed.
- Pump components that, due to their normal use, suffer wear and/or tear must be regularly replaced to ensure good pump
performance. The following table shows the perishables and/or consumables used in the pump and their estimated
working life.
COMPONENT DESCRIPTION
