Davey DT150KZN Dewatering Sump Pump 415V
WHY CHOOSE THE DAVEY KZN Sludge/Slurry sump pump?
Corrosion resistant 410 stainless steel shaft and stainless
steel shaft sleeve
• Long service life
• Impact resistant and long lasting
• Easily replaceable shaft sleeves save on shaft wear
Multivane, semi-open, wear resistant, high chrome impeller
• Ability to handle abrasive solid concentrations up to 70%
by weight
Pumps have a heavy duty high chrome agitator
• Keeps the flow chamber and impeller clear by causing the
solids to move in suspension, preventing the pump from
clogging
Double silicon carbide mechanical seals
• Abrasion resistant
• Located in separate oil chamber to protect the motor
• Added protection of a heavy duty lip seal
Top discharge with a motor water jacket
• Slimline design reduces the chance of damage to the
outlet in transit
• Allows for pumping within inches of the bottom, without
risk of overheating
Hardened ductile iron volute
• Cast with extra thick walls (300 Brinnell hardness) is twice
as abrasive resistant as standard ductile cast iron, which
ensures greater durability
Replaceable wear plate
• Hardened surface on suction side inhibits the occurrence
of erosion that could cause a reduction in pump
performance
Large open strainer
• Protects from larger solids entering the pump
Lifting rings
• For easy lifting and transportation of the pump.
Dimensions (mm): 565L x 485W x 1100H
Weight: 245Kg
Suitable Fluids
Water containing soft solids and/or hard solids in suspension,
up to 70% by weight. Some wear should be expected with
hard solid pumping. Not suitable for explosive or flammable
materials or fluids.
APPLICATIONS
• Ground & nuisance water removal
• Drainage from dams, sewer systems, tunnels, river
improvement projects & construction sites
