Features of EP

An All-in-one, High-to-medium Pressure Coolant Pump

All components of a coolant system are consolidated into a single YTH unit.
No line and suction filters are required. The use of a YTH unit reduces the required space to about 1/20th by volume of that occupied by a conventional coolant system.
The saved space expands the available plant space, resulting in a higher production efficiency.

• Maximum operating pressure: 7.0 MPa
• Maximum flow rate: 28.8ℓ/min
• No suction filter is required
• No line filter is required
• No clean tank is required
• No transfer pump is required on the coolant tank end
• No plumbing is required to interconnect various components

Plunger-type All-in-one High-pressure Pump

Turbulence™ filter With turbulence action, the sludge sticking to the filter is cleaned, rendering the filter clog-free.
Plunger pump / 7.0 MPa 〜 3.0 MPa Piston action pushes fluid at high to medium pressure.
Compatible with the TAZUNA™ fluid control system (software) TAZUNA reduces the electric power cost further by approximately 20%. The pressure and flow rate are automatically adjusted.

A sample configuration

Turbulence™ Filter

Our special Turbulence™ design generates turbulence around the surface of filter with 2 wing-shaped vanes rotating around filter and can wash away sludge from filter surface continuously.

Compatible types of chips

• ※ The use of any liquid containing abrasive stone/grain must be avoided.
• ※ Please contact us for the use of high hardness materials or Silumin (Silicon content of 6% or more).

Plunger Pump

Huge Energy Saving Effect Reduces Utility Costs

The use of YTH-EP results in huge energy savings over the conventional centrifugal pumps. The electric power cost is greatly reduced.
