Features & Benefits

The KB Series combines durability, abrasion resistance, and high hydraulic performance to provide a reliable solution for handling abrasive slurries. The integrated agitator ensures consistent solids suspension, improving pump efficiency and reducing maintenance requirements.

Top discharge design improves cooling performance and allows the pump to operate at lower water levels, enhancing overall usability in dewatering applications.

Construction and Operational Design

KB pumps are constructed using a combination of cast iron, ductile iron, and high-chrome iron components. The impeller, wear plate, and agitator are made from abrasion-resistant hi-chrome material, which significantly reduces wear in slurry applications.

The pump is equipped with a double mechanical seal system. The lower seal uses silicon carbide faces for durability in abrasive conditions, while the upper seal utilizes carbon/ceramic faces. A heavy-duty lip seal provides additional protection against fluid intrusion.

Each unit is powered by a high-speed 2-pole motor operating at approximately 3450 RPM. Class H insulation ensures the motor can withstand demanding thermal conditions, while built-in thermal and amperage protection safeguards against overheating.

A cooling jacket circulates pumped liquid around the motor housing, maintaining proper operating temperatures during continuous duty operation.
