E SERIES

A TurbulenceTM filter is built in
This is a YTH High-Spec Series.

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.
