Features And Benefits
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
