Hydroman^® offers the TBZ series and TBS series submersible pumps as direct, high-performance alternatives to the industry-standard KBZ and KBS pump lines — the TBZ is a fully interchangeable replacement for KBZ, and the TBS is a 100% compatible substitute for KBS, matching dimensions, mounting, and performance specs for easy drop-in replacement.

What Are They?

TBZ Series
A heavy-duty submersible dewatering pump built with a rugged cast-iron housing and a high-chrome alloy semi-open impeller for superior wear resistance. Its top-discharge, slim-profile design keeps the motor cool via a water-jacket cooling system, making it ideal for clean water, rainwater, and slightly sandy or muddy water applications.

TBS Series
A robust submersible slurry pump built on the same reliable TBZ frame, but fitted with an integrated high-chrome agitator beneath the suction inlet to break up and re-suspend settled solids. Powered by a 4-pole motor for extra torque and extended service life, the TBS is engineered to handle thick mud, sludge, and high-density sediment.

Why Choose Them?

TBZ Advantages

• High-head performance for strong pressure lift
• Wear-resistant high-chrome impeller with dual mechanical seals
• Reliable continuous cooling, even under partial-exposure conditions

TBS Advantages

• Anti-clogging agitator mixes settled mud and sand back into liquid form
• Extreme erosion resistance with high-chrome alloy wet-end parts (58+ HRC)
• Prevents solids buildup around the pump base for uninterrupted operation

Where to Use Them?

TBZ Applications: construction dewatering, deep excavation drainage, civil engineering projects, and mine/quarry dewatering with minimal abrasive solids.

TBS Applications: foundation and piling works with bentonite mud, settling basins and sumps with thick sludge, and industrial/municipal wastewater sites with heavy sand and sediment loads.

Whether you're upgrading from a KBZ/KBS setup or specifying new equipment, the Hydroman^® TBZ and TBS submersible pump series deliver equivalent — or superior — dewatering and slurry-handling performance with full compatibility.
