Tsurumi Replacement Diaphragms for 2″ & 3″ Trash Pumps

A worn-out Tsurumi replacement diaphragm is the fastest way to lose pumping power on a job site, and a cracked one can shut down dewatering work in minutes. Ken’s Distributing Company stocks diaphragms for the Tsurumi TD5-200 and TD5-300 mud and trash pumps in both rubber and neoprene. This page helps you match the right part number to your pump so you can order with confidence.

A diaphragm is the heart of these pumps. As the engine drives the diaphragm up and down, it pulls slurry, mud, and debris-filled water through the suction port and pushes it out the discharge. When that diaphragm hardens, tears, or stretches, suction drops off.

We supply parts for diaphragm-type trash and dewatering pumps used across construction, municipal, industrial, and agricultural work. Bulk and blanket orders qualify for volume pricing.

Available Materials

We stock the Tsurumi TD5 diaphragm in two compounds. Pick the material that fits your work.

Neoprene

A chloroprene compound resistant to abrasion, weathering, and moderate oil exposure, and well suited to rough outdoor environments.

Rubber

An abrasion-resistant compound for muddy, sandy, and grit-filled water.

If you are unsure which compound fits your application, call a pump specialist at (303) 699‑7845.

Signs It’s Time to Replace the Diaphragm

Swap the diaphragm when you notice any of the following:

  • Suction is weak or the pump loses prime
  • The discharge flow drops below normal
  • You see cracking, stiffening, or a tear on the diaphragm face

Keeping a spare on the truck means a quick swap instead of a lost afternoon.

Tsurumi TD5-300 Diaphragm — 3-Inch Pump

The TD5-300 is the 3″ model in the Tsurumi line. Both compounds share the same fit, so you only need to pick the material.

Part # Pump Model Size Material
2132-000-00-R TD5-300 3″ Rubber
2132-000-00-N TD5-300 3″ Neoprene

The base part number for the 2″ diaphragm is 3360-300-00. Add the -R suffix for rubber or the -N suffix for neoprene when you place your order.

If your crew runs both the 2″ and 3″ pumps, ordering matched spares for each keeps downtime low. We also stock a full range of diaphragm pump parts for other brands and sizes.

Tsurumi TD5-200 Diaphragm — 2-Inch Pump

The TD5-200 is the 2″ model. We stock its diaphragm in the same rubber and neoprene compounds.

Part # Pump Model Size Material
3360-300-00-R TD5-200 2″ Rubber
3360-300-00-N TD5-200 2″ Neoprene

Choosing Between Rubber and Neoprene

The right compound comes down to what you pump and where you work.

Neoprene

  • Water with light oil traces
  • Rough outdoor and weather-exposed settings

See our neoprene diaphragms to confirm the right part.

Rubber

  • Mud, clay, and sand-heavy slurry
  • Abrasive construction runoff
  • Grit-filled water

Where Tsurumi TD5 Pumps Are Used

These pumps handle thick, debris-laden water across:

  • Construction site dewatering
  • Mud, slurry, and sludge removal
  • Agricultural and irrigation water transfer
  • Municipal and utility maintenance

Because they move debris-laden water, the diaphragm takes real wear, so planning replacements before failure keeps projects on schedule.

Replacement & Maintenance Tips

A few simple habits extend diaphragm life.

  1. Inspect before each big job. Look for cracks, stiffness, and thin spots on the diaphragm face.
  2. Match the compound to the work. Choose rubber for abrasive grit and neoprene for weather and light-oil exposure.
  3. Keep a spare on hand. A truck-stocked diaphragm turns a failure into a quick swap.
  4. Clean the pump chamber. Flush grit and debris during every diaphragm change.
