Temperature
The life of the impeller depends on the
temperature of liquid being pumped.
Temperatures b5
°
C and +60
°
C
give normal life. Higher or lower tempera-
ture will reduce the life.
Freezing weather
Drain unit by loosening the endcover.
Glycol based anti-freezes can be used but do
not use petroleum based anti-freeze
compounds.
Endcover gasket
Use standard gasket. A thicker gasket will
reduce priming ability. A thinner gasket will
cause impeller to bind.
