What This Pump Is Designed For

The Tsurumi TD6-200 is purpose-built for applications where abrasive solids, thick sludge, or intermittent water flow would damage or stall conventional pumps.

Common applications include:

• Construction site dewatering
• Seepage and groundwater control

• Septic tanks and sewage transfer
• Rental fleet and utility use

This pump is especially effective in high water table environments and areas with thick, debris-laden material.

Why Choose the Tsurumi TD6-200?

True Dry-Run Capability

The TD6-200 is engineered to operate continuously without water, making it ideal for unattended pumping, seepage dewatering, and fluctuating water levels. While short-term deadheading is tolerated, proper operation practices help extend diaphragm life.

High Solids Handling

With the ability to pass solids up to 1-5/8″, this pump handles sludge, sand, and debris that would clog centrifugal trash pumps.

Durable Construction

• Sand-cast aluminum pump body balances strength and portability
• 90° rotatable base allows flexible hose routing on tight jobsites
• Modular frame, handle, and wheel components for jobsite durability

Fully Serviceable Design for Long-Term Use

The TD6-200 is not a disposable pump. It is built for long-term professional use, with every major component individually serviceable, including:

• Replaceable thermoplastic rubber diaphragm and retaining plate
• Serviceable plunger and crank assembly
• Replaceable neoprene check valves and valve weights
• Fully enclosed, oil-filled gearbox and seals
• Engine mounting and drive components

This fully serviceable design simplifies routine maintenance, reduces downtime, and lowers total cost of ownership making the TD6-200 especially well suited for contractors, municipalities, and rental fleets operating in harsh environments.

What This Pump Is Not Intended For

For transparency and proper application:

• Not designed for clean water, irrigation, or high-volume transfer
• Not a replacement for high-flow centrifugal pumps
• Not intended for continuous high-pressure deadheading

Choosing the right pump for the job ensures best performance and service life.
