Features of EP

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

Features of EP

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).

Filtering performance

Suction strainer3mm (Solids larger than this must be removed in the tank)

High efficiency plunger pump

  1. ■ Compatible types of fluid
    • Water-soluble coolant fluids
    • Not for lubricant oil or fuel oil
    • Not for clear water, purified water, aqueous solutions and viscous fluids without rust-preventive property, corrosive liquid, solvents, and oils
  2. ■ Relief valve is built into the unit
