Permanent installation
1. Submersible slurry pump
2. Overflow alarm
3. Level control equipment with float switches
4. Hose
5. Non-return valve
6. Lifting tackle
• The pump must not be submerged to more
than 20 metres/65 feet. IP-68.
• The temperature of the medium must not
exceed 40°C/103°F.
• The pH-value should be between 4 and 10.
• The voltage drop in operation must not exceed
5 %.
• Maximum numbers of starts per hour:
15 evenly spread.
• Maximum cable lengths.
Excessively long cables cause voltage drops
that can result in malfunctions.
• By using a cable of greater conductor cross-
section you reduce the voltage drop and can
therefore increase the cable length.
• Pressure losses.
Long or unnecessarily small-bore hoses give
substantial pressure losses.
Respect limitations
In order to decide what pump would be best for
a permanent installation you will need to know
the following:
• Type of medium (sludge, abrasive, corrosive, etc.)
• Inflow of liquid
• Head
• Desired pump capacity
• Size of the pump sump
• Size and length of discharge pipe, number
of bends and valves, etc., for calculation of
WARNING!
The pump should not be used in explosive or
fire-risk conditions or for pumping inflammable
liquids.
WARNING!
Don’t go near rotating parts of the pump.
